城镇圩区排涝模数计算方法及其与河道调蓄库容关系研究

Study on Drainage-modulus-calculation Method and Its Correlation with the Regulation Storage in Urban Diked Area

农业圩区原有的排涝模数计算方法已不适用于城镇圩区。针对城镇圩区的排涝特殊性,通过分析排涝计算的原理,充分考虑圩区内河道的调蓄能力,得到适应城镇圩区排涝计算的方法。以南京市江宁区为例,对城镇圩区的排涝模数进行计算,得到排涝模数与调蓄库容之间的定量关系。

The calculation method of drainage modulus in agricultural diked area is inapplicable in urban diked area. Aiming at the drainage specialties of urban diked area, we analyze the principle of drainage calculation and obtain a drainage-modulus-calculation method for the urban diked area with full consideration of river-storage capacity. Taking Jiangning District in Nanjing City as an example, the drainage modulus of its urban diked area is calculated, then the correlation between drainage modulus and regulation storage is educed.
