小型水库的调洪计算,一般用分时段调洪法计算,但很繁琐和费时,用Д、И高切林公式的为数也不少,对于小集雨面积的水库误差一般为大40％以上,大的可达69％,尤其是小二型水库,一般都用Д、И高切林公式计算,误差更大。为了解决这些问题,在保证精度要求的前提下,研究出新的简捷调洪计算方法。
The calculation of flood regulation of small reservoirs is usually calculated by time-sharing flood regulation method, but it is very tedious and time-consuming. There are also a large number of Д and И high-cutin formula, and the reservoir error for small rain catchment area is more than 40% , Up to 69% of the large, especially small two reservoirs, are generally calculated with Д, И high cutlin formula, the error greater. In order to solve these problems, under the premise of ensuring accuracy requirements, a new simple method of flood control calculation is developed.
