Method and system for calculating river networks model

Abstract

The invention provides a method and a system for calculating a river networks model. The method and the system are used for carrying out numerical simulation analysis on water flow movement of rivers based on a hydraulic principle so as to accurately master and forecast water regime of the rivers. The method and the system have the advantages of high calculation speed, capability of supporting various types and the like.

Description

technical field [0001] The invention relates to the field of calculation of river network models. Background technique [0002] The existing water level simulation calculation software, including the British ISIS commercial software platform, cannot calculate the geometrically complex river network structure, including the topological connection of any internal loop loop, and cannot reflect the relationship between the tidal reach and the loop. The reciprocating flow in the shape of the river, can not handle the dry bed and alternating wet and dry conditions well, can not deal with barrage gates, poor fault tolerance to basic data, can not deal with random cross-section shape, poor stability and speed , poor scalability and other issues. [0003] This makes it impossible for builders who need to build riverside buildings and river facilities to simulate the relationship between these building facilities and the water level boundary and water level flow of the corresponding ...

[0002] The existing water level simulation calculation software, including the British ISIS commercial software platform, cannot calculate the geometrically complex river network structure, including the topological connection of any internal loop loop, and cannot reflect the relationship between the tidal reach and the loop. The reciprocating flow in the shape of the river, can not handle the dry bed and alternating wet and dry conditions well, can not deal with barrage gates, poor fault tolerance to basic data, can not deal with random cross-section shape, poor stability and speed , poor scalability and other issues

[0003] This makes it impossible for builders who need to build riverside buildings and river facilities to simulate the relationship between these building facilities and the water level boundary and water level flow of the corresponding river when the facilities they will build exist around any actual river, and through multiple simulations , to analyze where the construction can achieve the least construction resistance, the least impact by river movement, the least erosion and corrosion caused by river movement, and the least damage caused by extreme river conditions, so it is impossible to scientifically and accurately analyze the engineering buildings around any river Feasibility and plan the most reasonable building location
