离散广义Nash汇流模型及其在河道洪水演算中的应用
The discrete generalized Nash Model and its application in the river flood routing
摘要
Abstract
Based on the generalized Nash flow routing theory,the calculation formula was simplified by the definition of S-curve or detention storage curve.The discrete generalized Nash model (DGNM) for river flow routing was derived.The outflow downstream can be expressed by a linear combination of the inflows at the beginning and end of the current time,and the outflows of the current time and several times before.The weight coefficients of the linear combination were obtained by the defined S-curve or detention storage curve.The DGNM,with a clear physical concept,also has a statistical significance.Its structure is very simple and its form is more intuitive,which facilitates its popularization and application in practice.The case study also suggested that the DGNM has a good forecasting ability.关键词
