- Figure 4 represents a second variant of the water characterization and sampling process according to the invention.
- the invention relates to an airborne system for characterizing and sampling water from an aquatic environment (which can also be called an aqueous environment).
- the aquatic environment can be a lake, a pond, a river, a sea or an ocean and more particularly, it can be a source of water (more particularly fresh water) underwater or coastal which opens in a sea or an ocean.
- aqueous medium or “aquatic medium”, we mean a medium composed essentially of water, that is to say mainly water.
- the water surface can then be very strongly disturbed by waves, swell, current or the presence of the nearby coast so that the detection of the nearby fresh water source is made difficult as is the characterization. and the withdrawal of this water.
- the system includes an aerial drone equipped with various payloads, also called UAS (for “Unmanned Aerial System” in English, which means Unmanned Aerial System).
- UAS for “Unmanned Aerial System” in English, which means Unmanned Aerial System.
- an aerial drone is a drone capable of being moved by air, with a pilot not on board the drone (on the ground for example) or automatically controlled by a computer system (for example a computer, a server or a calculator).
- the drone is configured for automatic or manual radio-controlled piloting.
- the UAS can be brought into areas of difficult access such as near a coastal area at sea or in a particularly steep area in the mountains.
- This aerial drone may not include a system landing: it is therefore simpler, cheaper, less heavy and less complex than a drone with a landing system.
- the aerial drone includes an optical sensor in the visible light spectrum and/or an optical sensor in the infrared spectrum.
- These different sensors are an aid in determining potential study areas or “areas of interest”, based on the color of the water which is different between fresh water and sea water, thanks to the sensor. optical in the visible light spectrum, and/or from the water temperature (by the optical sensor in the infrared spectrum).
- optical in the visible light spectrum and/or from the water temperature (by the optical sensor in the infrared spectrum).
- the aerial drone is also equipped with data reception/transmission means (receiver/transmitter for example).
- the UAS can receive information (to control a winch and/or measuring probes for example), this information can for example come from a user.
- the aerial drone can also receive information from measurement data, for example from water measurement sensors. These data are then recorded (stored) in the data reception/transmission means (in a computer or electronic card for example).
- the aerial drone can also transmit data: for example, it can transmit measurement data either in real time to a user, or after their storage and retrieval by the user via the computer or electronic card for example.
- the UAS further comprises a geolocation means, which can advantageously be included in the data reception/transmission means (for example, the system known as GPS for “Global Positioning System” or GNSS for “Global Navigation Satellite System” meaning satellite positioning system in French, GNSS being able to capture GPS satellites or other constellations such as Galileo, the European system, Glonass, the Russian system, or even the Chinese system).
- GPS Global Positioning System
- GNSS Global Navigation Satellite System
- Galileo the European system
- Glonass the Russian system
- Chinese system the precise position of the drone can be known at the time of measurements and/or water sampling.
- the geolocation data from the geolocation means can be received in the data reception/transmission means (the computer or electronic card for example) and/or be transmitted to a user (via the computer or electronic card for example or by real time).
- the system comprises an instrumentation device comprising at least one means for sampling water from the aquatic environment, a first winch mounted on the aerial drone and capable of positioning the instrumentation device at a predetermined depth in the environment aquatic.
- an instrumentation device comprising at least one means for sampling water from the aquatic environment, a first winch mounted on the aerial drone and capable of positioning the instrumentation device at a predetermined depth in the environment aquatic.
- the drone can also be programmed so that it follows a sampling plan composed of several geolocation positions in the area of interest and one or more water depths for each geolocation position.
- the sampling means may comprise at least one open container, such as a reservoir or a bottle.
- it may include at least one instrument such as a syringe equipped with a piston. Moving the piston located inside the syringe in one direction to increase the internal volume of the syringe allows water to be drawn from the aquatic environment; moving the piston in the opposite direction allows the syringe to be emptied.
- the sampling means can advantageously be configured to be able to sink even when empty, so as to facilitate its immersion to the desired depth.
- the aerial drone is able to be maintained in an aerial position during the sampling and/or characterization of water (it therefore does not need to land to carry out the measurements and/or the water sampling and it may therefore not include a landing system) and the instrumentation device comprises a data acquisition means (probes or measurement sensors, for example autonomous data acquisition probes used for measurement and recording parameters such as level, temperature and electrical conductivity) to measure at least the pressure, temperature and/or conductivity of water within the aquatic environment.
- a data acquisition means probes or measurement sensors, for example autonomous data acquisition probes used for measurement and recording parameters such as level, temperature and electrical conductivity
- Autonomous data acquisition probes may in particular be probes known as Diver probes, to measure level, temperature and conductivity.
- the data acquisition means can be connected to the cable control means or be radio controlled.
- the data acquisition means can also include multi-parameter probes to measure both the level, the temperature and the electrical conductivity and at the same time other parameters such as pH, dissolved oxygen level and/or turbidity.
- the acquisition means may comprise at least one piezometric probe, in particular at least one autonomous piezometric probe with data acquisition.
- the drone can be moved away from the water surface and thus it is no longer or very little exposed (only through the cable of the first winch and a possible second winch) the impacts of disturbances to the water surface in particular linked to swell, current or presence of the coast nearby.
- the system can be used in areas where landing is impossible and/or where the water is strongly disturbed (for example, in a river) or too small.
- the data acquisition means allows measurements of pressure, temperature and/or conductivity of water in situ. It can thus include a sensor for measuring the pressure, temperature and/or conductivity of the water within the aquatic environment itself.
- the use of these in situ data makes it possible to predict or not a water withdrawal at this given location (from geolocation) and at the given depth (from the first winch). Indeed, if the measured pressure, temperature and/or conductivity data of the water are not satisfactory, water sampling is then not necessary.
- the data measured by the data acquisition means make it possible to establish a first selection of water to carry out or not a water sample. We can then reduce the number of samples to be taken. Sampling the water makes it possible to complete the characterization of the water which was made by the means of data acquisition by other complementary measurements of the water, these complementary measurements not being possible in situ and allowing to access additional water characterization characteristics.
- the combination of a sampling means with a data acquisition means thus makes it possible to make the characterization of water faster and more efficient and to target the area of interest more quickly, while being precise.
- Measuring pressure, temperature and/or conductivity makes it possible to evaluate the density and/or salinity of water.
- we can know thanks to these measurements if at the identified geolocation point and at the identified depth, the water corresponds to fresh water or not.
- 3D mapping which can be carried out on the area of interest and for different water depths, we can characterize the most interesting location for capturing drinking water, this location possibly depending on the outlet of the water. one or more sources, current, swell and the presence of the coast nearby for example.
- the data acquisition means can enable the transmission of data in real time by means of data reception/transmission.
- Real-time transmission of acquired measurement data accelerates characterization and reduces intervention time.
- the optical sensor may comprise an optical sensor in the visible light spectrum and/or an optical sensor in the infrared spectrum.
- the optical sensors can be cameras.
- a thermal camera also called an infrared camera, detects and measures light waves whose spectrum is in the infrared range. It makes it possible to determine the temperature of a body by the infrared radiation it emits.
- the viewing camera is an optical or digital camera that allows you to view the environment much like the human eye. It detects objects in the visible range between red (infrared excluded) and violet (ultraviolet excluded).
- the optical sensor is on the aerial drone, it is located above the surface of the water and makes it possible to detect variations in color and/or temperature to determine an area of interest in which it will be interesting to carry out measurements and/or taking water samples.
- the optical sensor By analyzing both the measurement of the optical sensor in the visible light spectrum and that of the optical sensor in the infrared spectrum, we can cross-reference the data and define a more precise area of interest. This makes it possible to accelerate the characterization of the water and to better target the area where it would be interesting to capture fresh water, for example.
- the data acquisition means may also include a means of measuring the pH, the level of oxygen dissolved in the water and/or the turbidity.
- the measured temperature and pH can in particular provide information on the origin of the water: these data can provide information on the original aquifer, the land drained by this aquifer, but also the very origin of the water, whether this either for example meteoric (rain) water infiltrated into the aquifer, sea water reinjected into the aquifer, or deep underground formation/hydrothermal water.
- Dissolved oxygen refers to the level of free, uncompounded oxygen present in water or other liquids. It is an important biological and chemical parameter in the assessment of water quality due to its influence on living organisms in a water body. Too high or too low dissolved oxygen levels can harm aquatic life and water quality. For example, a rate between 0 and 2 mg of dissolved oxygen per liter (1 liter corresponding to 0.001 m3) of water, the oxygen level is insufficient for the survival of most organisms. Between 2 and 4 mg of dissolved oxygen per liter of water, the oxygen level only allows certain species of fish and insects to survive. Between 4 to 7 mg of dissolved oxygen per liter of water, the oxygen level is acceptable for warm water fish species but it remains low for cold water fish species while a level between 7 to 11 mg of dissolved oxygen per liter of water is ideal for most cold water fish.
- Turbidity measurement makes it possible to identify the quality of the water and any suspended particles it contains. All these measurements can be integrated into a single sensor such as an autonomous data acquisition probe.
- turbidity refers to the content of water in suspended particles and colloidal particles which absorb, diffuse or reflect light and therefore cloud the water. It is therefore, as with dissolved oxygen, an indicator of water quality.
- turbidity is measured in nephelometric turbidity units (uTN) using a turbidimeter. For example, at 5 uTN, the water is visibly cloudy while at 25 uTN, it is blackish.
- the system can include a second winch mounted on the aerial drone and capable of emptying the sampling means.
- a second winch mounted on the aerial drone and capable of emptying the sampling means.
- This rinsing operation may in particular comprise at least one filling of the sampling means with water from the aquatic environment, followed by emptying of the sampling means, preferably at least three fillings, each filling being followed by emptying of the means. sampling.
- the sampling means is a tank
- one end of the tank can be attached to the first winch and thus allows filling
- the second end of the tank can then be attached to the second winch.
- the sampling means may comprise several sampling reservoirs and/or several instruments such as syringes.
- a specific point at a specific location
- a separate sampling reservoir or a separate syringe
- Water can also be taken from a sampling tank for different determined points (at different locations) for the same depth or for different water depths.
- the system is very flexible in terms of uses, and it is faster to take samples. When the sea is very rough, this also reduces intervention time and limits the risk of equipment damage.
- the system may include a means of processing images from the optical sensor, such as image processing software.
- image processing software can be faster than human processing, for example by establishing pre-established criteria indicated in the software and on the other hand, this image processing can be carried out in real time, which further shortens the intervention and water characterization time and facilitates decision-making as to to the definition of the area of interest.
- the water sampled can be analyzed in the laboratory. For example, a study of water isotopes and organic carbon measurements provide information on the residence time of water in the geological reservoir (an aquifer for example).
- the residence time of water in the aquifer provides information on the transfer duration and therefore indirectly on the permeability of the land.
- the residence time can be extremely short (from a few days to a few weeks), which is due to the presence of caverns and underground voids. These voids can act as temporary storage (buffers) which will delay the transfer of water between the recharge and the outlet.
- the residence time also gives an indication of the speed of water renewal in the aquifer. In the case of an exploited aquifer, this is therefore major information for estimating the sustainability of the resource, and improving its sustainable management by establishing hydrodynamic models. It is also an important parameter for estimating the sensitivity to pollution of the aquifer: an aquifer with a short renewal time will be very sensitive to the potential arrival of pollutants. It can nevertheless return to a good chemical state if the source of pollution is stopped. An aquifer with a long residence time, if contaminated, will not be able to quickly recover a good chemical state.
- the invention also relates to a method for characterizing and sampling water from a system as described above, for which at least the following steps are carried out: a) the aerial drone is moved by air above an aquatic environment. As a result, the system and the method can be used in areas of difficult access and/or in areas where water conditions (particularly on the surface) are strongly disturbed. The aerial drone does not require a landing system. b) the (at least one) optical sensors are used to determine a zone of interest in which the water is to be characterized. Using these optical sensors located beneath the aerial drone, one can view the water surface at an altitude of the drone above the surface.
- This aerial visualization allows you to visualize a difference in water color (optical sensor in the visible light spectrum) or a temperature difference (optical sensor in the infrared spectrum). This difference in color and/or temperature can then be used to identify an area of interest where the water will be characterized. By using both the optical sensor in the visible light spectrum and the optical sensor in the infrared spectrum, we can narrow the area of interest, that is to say limit the extent of this area and therefore improve its precision. . c) the aerial drone is stabilized in hover at a predetermined point above the determined area of interest. By remaining in hover, the aerial drone is not (or very little via the first winch) subject to water disturbances, and in particular to disturbances of the water surface. The aerial drone is therefore kept safely away from the water surface.
- the optical sensor can still be used simultaneously.
- a location measurement is acquired from the geolocation means so as to be able to precisely determine the location, then the first winch is used to lower said instrumentation device to a first predetermined depth. in the aquatic environment.
- the winch cable that is subject to the disturbance of the water surface. Consequently, it is little disturbed and the measurements remain precise (the measurements and samples taken are taken at the determined location).
- the first characteristics of the water such as the density and/or the salinity of the water and therefore identify, for example, whether or not it is drinking water (water is considered drinkable if its salinity is less than 0.2g/L according to WHO standards).
- the measurements can be acquired in real time. This allows for faster analysis and avoids unnecessary water sampling if the salinity is too high, for example.
- water is sampled in the aquatic environment at the first depth using the sampling means (a reservoir or a sampling syringe for example) and additional analyzes are carried out on the water sampled to carry out a second characterization some water.
- the water sampled allows additional analyzes in the laboratory, these additional analyzes not being possible directly in situ and making it possible to define second characteristics of the water or to refine the first characteristics of the water to make them more precise.
- water can be sampled in the aquatic environment at the first depth by the sampling means if the data acquired from pressure, temperature and conductivity, and possibly pH, dissolved oxygen level in the water and/or turbidity, check predetermined criteria, for example if the salinity of the water, determined from the measurements, is less than 10% of the salinity of the surrounding environment. Otherwise, we can move the aerial drone to another point in the determined area of interest and we continue from step c). If the predetermined criteria are not verified (if the salinity is too high), the point is deemed not of interest, sampling is then not necessary and the process consists of finding another point above the area of interest determined.
- a rinsing phase of the sampling means before carrying out each water sampling, this rinsing phase comprising at least three repetitions of the sequence in which the means of sampling are filled. sampling with water from the aquatic environment and the water is emptied from the sampling means, preferably using a second winch.
- the complementary analyzes of the water may include an analysis of water isotopes and/or chemical measurements preferably including measurements of organic carbon. These analyzes provide information on the residence time of water in its geological reservoir.
- different measurements can be acquired using the data acquisition means at different first predetermined depths and/or at different predetermined points above the determined area of interest.
- we can establish a map of the characterization of water in the area of interest and thus identify the most interesting place to capture fresh water, for example.
- the measurements can be acquired by means of data acquisition and preferably, water can be sampled by means of sampling, without having to reassemble the instrumentation device by the first winch.
- the characterization of the water is more precise and the mapping that can be established can also be more precise.
- intervention time is reduced.
- these samples and acquisitions can be carried out in real time to further accelerate the characterization of the water and possibly further gain in precision.
- the aerial drone, the optical sensor, the geolocation means, the first winch and the possible second winch can be controlled by several control means.
- the aerial drone, the optical sensor, the means of geolocation can be controlled by a first control means (control of a first user for example) and the control of the first winch, and the possible second winch, can be controlled by a second control means (control of a second user distinct from the first user for example).
- the first user can concentrate exclusively on piloting the aerial drone and the second user takes care of manipulating the instrumentation device to carry out the necessary measurements and/or samples (and the possible rinsing of the sampling means through the second winch).
- operations are secure and the risk of hardware loss of the system is reduced, each user having a unique function.
- the first user and the second user can be replaced by a computer.
- digital processing of the images from the optical sensor can be carried out to determine the area of interest.
- This digital processing can make it possible to narrow the area of interest by limiting its extent or obtain the area of interest more quickly or more efficiently.
