Study on Flow Characteristics of Jingjiang River
摘要
Abstract
The Yangtze River Flood Protection Physical Model is employed to comprehensively measure the hydraulic elements for different flow discharges of Jingjiang river. Furthermore, the water sediment and topography data since the impoundment of Three Gorges Reservoir were taken to analyse the general laws and characteristics of flow movement. Based on the above analysis, different river regulation programs are studied and detailed solutions for different river regimes are offered. The study reveals the flow movement rules for Jingjiang River by clearly presenting the inherent laws of hydraulic elements variation including that of the water level, water surface longitudinal slope, breadth to depth ratio of cross section, flow velocity distribution and dynamicaxis of flow, and consequently provides scientific basis for river regulation.关键词
