采用数理模型通过电子计算机进行模拟，计算，分析大面积排水，已在各国广范应用．作者利用这一方法，对挠力河流域进行了1981年洪水演算，证明这一方法可以在实际工程中加以推广和应用．除此之外，还可以求出排水渠道的糙率，及流域的径流系数（排水模数）；还可以验证排水渠的排水流量、水位、流速，用多大的泵能解除洪涝，哪一段排水渠需要加宽等等，可作多种方案的比较和优选．
Using mathematical models to simulate, calculate and analyze large-area drainage through electronic computers has been widely applied in various countries. Using this method, the author carried out the 1981 flood calculation to the Naoli River Basin, which proves that this method can be popularized and applied in practical engineering. In addition, the roughness of drainage channels and the runoff coefficient (drainage modulus) can also be calculated. It can also verify drainage flow, water level and flow rate of drains, how big the pumps can dispel floods and which drainage Drainage need to be widened, etc., for a variety of options for comparison and optimization.
