Description
Technical field
The utility model relates to hydraulic engineering technical fields, pre- more particularly, to a kind of riverbed water level monitoring unit and mountain torrents
Alert system.
Background technique
Mountain torrents generally refer to occur in the Mountain Area small area (within usual several hundred km2), risen urgency by the urgency that heavy rainfall induces
Fall the flood of (dozens of minutes to a few houres).The harmfulness of mountain torrents is mainly shown as that sudden, water is concentrated and flow velocity is big, washes away
Power is strong, and a large amount of silts, stone etc. is usually swept along to form mud-rock flow and landslide, has powerful destructiveness.In recent years, due to the whole world
The reason of climate change, causes extreme weather to continuously emerge, and extramalization trend is presented in the variation of rainfall, therefore causes global mountain
The frequent generation of disaster, coverage increase year by year.
Currently, both at home and abroad there are two types of common mountain torrents early alarming and forecasting methods, first is that the mountain torrents based on hydrological distribution model
Forecast, as the organization development of Henan Department of Water Resources of Shanxi Province " the mountain flood early-warning and predicting system based on hydrological distribution model " in take
Be exactly this technological approaches；Secondly being the mountain torrents early warning based on dynamic critical rainfall, as U.S. hydrologic research center is researched and developed
Mountain torrents instruct (FFG method) method.In addition, empirical method can be used to the small watershed with certain series of hydrological data, such as foundation
This basin observational data establishes quantum of rainfall forecasting and warning scheme relevant to flood peak.
Mountain torrents early alarming and forecasting method based on hydrological distribution model, basic ideas are to utilize high accuracy number elevation mould
Type (DEM) generates Digital Valley, inquires into diameter using existing hydrological model on each small sub-basin (or DEM grid)
Stream, then confluence calculation (instantaneous landforms unit hydrograph method, area-time method etc.) is carried out, finally acquire each sub-basin (or grid)
The flood forecastings data such as discharge process, peak flow and the peak flow time of occurrence of mouth section；According to the hydrology of real-time monitoring
Data, in conjunction with the rainfall runoff situation for calculating resulting each small watershed.Once reaching early warning limit value, pass through network system and flood control
Short message platform sends warning information to related responsibility personnel.
The difficult point that this method is applied is: 1) mountain torrents easily send out ground often hydrological data shortage, modeling and verifying difficulty；2) every
The determination of the mountain torrents warning index (water level, flow) of a sub-basin；3) it must be set up the flood information mechanism for being suitable for mountain torrents forecast, add
The secret report flood frequency；4) current rainfall network lays the requirement for being difficult to meet mountain torrents forecast, it is necessary to easily send out zone encryption rain in mountain torrents
Amount station net；5) it needs that the following rainfall forecast is combined to carry out hydrological simulation calculating, to improve the leading time of mountain torrents forecast.
FFG method based on dynamic critical rainfall, thinking are the rainfalls to have occurred on small watershed, pass through hydrological model
Analysis is calculated, the real-time soil moisture in basin is obtained, anti-basin Outlet Section crest discharge of releasing will reach preset early warning
Rainfall needed for flow value, this rainfall are referred to as " FFG value " or dynamic " Critical Rainfall value ".When real-time or forecast drop
When rainfall reaches " FFG value ", i.e. publication mountain torrents early warning or warning.In general, when analyzing current soil moisture, because of the time
Allow, has used hydrological model, obtained FFG value；When issuing predictions for future or early warning, because of time is pressing, the hydrology is not run
Model, only comparison is when whether point (or small-scale face) rainfall reaches and more than FFG value, decides whether to issue early warning.
Difficult point of this method in practice: 1) for the basin of non-avaible or data shortage, the parameter of hydrological model
Acquisition be also very difficult；2) how by region correlation analysis to determine that river cross-section parameter is a critical issue；3)
It must be set up perfecting mountain torrents historical data base to verify mountain torrents early warning.
In summary, distinct issues the most existing for current mountain torrents method for early warning common both at home and abroad are exactly for data
The basin of shortage, establishes reasonable hydrological model and actual parameter is extremely difficult, and this problem is distributed China's middle and small river
There is biggish operating difficulties for the real features such as numerous, watershed unit is complicated and changeable, the effective daily management of shortage.Especially
It is, for across level-one administrative region, the middle and small river across totally different geology and geomorphology, to face abnormal rainfall risk, weather is pre- in short-term
In the case where standard of reporting lost property to the authorities, mountain torrents early warning problem just seems especially prominent, if not can effectively solve the technical problem, it will generates
The unexpected storms that can not be estimated.For example, summer in 2012, occurs to make in the extra torrential rain in Beijing and Hebei boundary kinfe rest river valley
At mountain flood, just there is this typical category feature.
Moreover for numerous middle and small rivers, river topography landforms are complicated, using existing common mountain torrents alarm mode,
Excessively complicated and cumbersome operating difficulties will be brought, and not used.Therefore, there is an urgent need to a kind of simple and practical technologies and operation
System, to across level-one administrative region, the middle and small river across totally different geology and geomorphology carry out timely mountain torrents early-warning and predicting or conduct
To a kind of supplement of existing mountain torrents method for early warning system.
