Wetted Perimeter Approach to Estimate Instream Flow Requirements: A Case Study in Luanhe Water System
湿周法估算河道内最小生态需水量——以滦河水系为例

Wetted perimeter approach estimates instream flow using wetted perimeter as an index to scale the habitat quality.It estimates minimum environmental flows via determining break point on curve of the relationship between wetted perimeter and discharge.This paper adopted logarithmic and power function methods respectively to simulate the relationship between wetted perimeter and discharge based on the foreign experience of research and application.The difference of determining breakpoint using slope equaling ...
