弯滩河流域梯级开发中水文分析

Hydrological Analysis of Wantan River Valley for Cascade Development

在流域开发规划中，水文分析至关重要。本文对重庆市巫溪县弯滩河流域及其流域上拟建的五座电站的坝址处进行了径流分析和计算，并对盐渠水文站洪水分析和频率计算，得出了各梯级电站的设计洪峰流量及洪水过程线，为弯滩河流域梯级开发提供了水文依据。

Hydrological analysis is crucial for the valley development planning. The runoff was analyzed and calculated for the Wantan River watershed, located in Wuxi country, Chongqing city, and on the feet of dams which are planned to build in the valley. At the same time, the design flood peak discharge and hydrograph are calculated by analyzivg the flood of YanQu gauging station and the frequency of the flood. Therefore, it provides the hydrological characteristics for the cascade development on the Wantan River.
