河道洪水演算很复杂,但如果用“调蓄经验单位线”方法,将会有许多好处:参数可以从洪水过程线上直读,不限制演算时段的长度,不限制演算河段的长短,无S曲线或汇流系数表。输入、运算和打印仅17行程序。实例表明,洪水预报精度改善,同时有0.5Δt的预见期。 River flood calculation is complicated, but there are many benefits to using the “unit-of-experience” method: parameters can be read directly from the flood process, without limiting the length of the calculation period, without limiting the length of the calculation channel, without S curve or bus coefficient table. Enter, calculate and print only 17 lines of program. The example shows that the accuracy of flood forecasting is improved with a 0.5t forecast period.
