4.4 Structure of a hydrological modeling system

The structure of hydrological modeling tool mainly consists of four structural parts： ①general GIS software for hydrological analysis; ②pre-processing module; ③ computational module; ④post-processing module.A hydrological modeling system contains many functions involving a lot of algorithmsand procedures.These functions are encapsulated into different modules.Besides，considering the language model developers used，the whole platformwill be organized as an integration of all functional components and algorithms，and the development languages includes C++，C#，VB.Net (programminglanguages suitable for interface development) and Fortran (a computationalefficient language for scientific research).System structure of hydrologicalmodeling system is shown in Figure 4-1.The main f ......     （共1040字）    [阅读本文]>>
