1. the reservoir inflow of reservoir is forecast and is painted on a figure with the relevant curve of reservoir routing by the present invention
On, it is possible to shorten the formulation time adjusting flood scheme, be effectively improved the ageing of small reservoir forecast.
2. achieve the excavation to historical summary and calibration.
3. it is that one calculates means fast and easily, small reservoir is managed and protected personnel ability less demanding.
Accompanying drawing explanation
Fig. 1 is that the four-quadrant that the present invention draws implements illustration.
Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment the present invention is described in further detail.
As it is shown in figure 1, Small Reservoir intelligence four-quadrant adjusts flood method, including:
