According to largest quantity of free discharge and order of designing peak flow quantity in the flood discharge, flood regulation routing formula of general graph is computed.
根据涵洞最大自由泄洪流量和设计洪峰流量在泄洪运行中出现的前后顺序，推算出概化图形的调洪演算公式。
Through comparison between safety discharge and peak flow, building a model to determine the flood control capacity on river and reservoir.
通过对比安全泄量和洪峰流量，建立确定堤防、水库防洪能力大小的模型。
The total flood volume is reduced, the flood duration is prolonged, the peak flow is decreased dramatically, and the flood hydrograph is characterized by the rapid rise and mitigatory recession;
洪水总量减少，洪水历时延长，洪峰流量显著降低，洪水过程线表现为涨洪陡、落洪慢的特点；
