Background
The hydrological measurement station is a basic hydrological mechanism for observing and collecting hydrological and meteorological data of water bodies such as rivers, lakes, reservoirs and the like. The content of the hydrological measurements is closely related to the environmental impact prediction method to be employed. When the mathematical model is adopted, the contents of the mathematical model are determined according to the requirements of the selected prediction model, the environmental hydrological characteristic value and the environmental hydraulics parameter which are required to be input.
The hydrological measurement station refers to a measurement point which is positioned beside water bodies such as rivers, canals, reservoirs and the like, and the system observes water level and flow. From the continuous records from these stations, the hydrologist can forecast water levels, flood activity, decision controls, shipping, and the like. The observation instrument has a scale and a self-metering water meter. The scale is inserted into water and read by observing the position of water surface contacting with it. The self-metering water meter continuously monitors the water level, automatically detects the water level by a detector or a buoy, and records the water level on a movable paper sheet by a pen or a printer.
