洪峰流量模数 meaning in English

peak flow modulus

In harnessed watershed , a is smaller and b is bigger , but they are contrary in no - harnessed watershed . the flood peak volume modulus and sediment transport modulus is also power function relationship . but parameter a and b is different largely in different watershed and the relativity is not well than relationship between runoff depth and sediment transport modulus
参数a 、 b可以反映流域有无治理的差异，参数a在有治理或部分治理的流域内均小于无治理流域；参数b在有治理流域内则较无治理流域偏大；流域次降雨洪峰流量模数与输沙模数也为幂函数关系，但参数a 、 b在不同流域之间差别较大，其相关性不如径流深与输沙模数关系好。
