Evaluation and Forecasting Model for State of Drought in the Irrigation Reservoir

관개저수지의 한발평가 및 예측모형(관개배수 \circled2)

The severity of drought could be evaluated by the accumulative rainfall method, soil moisture condition method, storage ratio method, and water supply restriction intensity method, etc. The pattern of drought could be forecast with the most similar pattern of accumulative rainfall out of the file of past rainfall history. The information that how much rainfall should be expected to overcome the present drought could be obtained from the reservoir storage ratio and soil moisture condition.
