| Abstract: | The new numerical method and advance in one-dimension river modeling are resumed in this paper, in which two parts for the numerical method and application in engineering are described in detail. The first part principally contains the numerical difficulty and difficulty of modelisation, as well as validity approaching the actual condition, and it describes and introduces the basic principles that are used to resolve those difficulties. The second part principally contains the demand in engineering for the numerical modelisation and treatment of actual boundary condition, it describes the recent advance of the mathematical models of rivers and their actual application in engineering. |
