Analysis of trunk stream and tributary flood encounter for Hongshui River and Qingshui River
Qingshui River is one of the tributaries of Hongshui River and they merged at Qianjiang Town. Taking the river section at Qianjiang Town as example, flood synthesis was analyzed, the design flood level at estuary sec?tion of Qingshui River was calculated taking into account the backwater effect from Hongshui River. The water sur?face profile of design flood is the major basis of dike design. For the river section influenced by backwater of trunk stream and tributary, flood synthesis and encounter rule shall be analyzed, water surface profiles corresponding to various synthesis conditions shall be calculated, with the envelope curve as design basis.
