Discussion of theory and methods for building a distributed hydrologic model;

One arithmetic of the grids conflux order in the distributed hydrologic model based on Muskingum method

Studying the needed catchment information of model based on study of distributed hydrologic model,in order to obtain the needed parameter information for designing the procedure to extract the catchment information,giving a serial number for each drainage system according to the water chain and obtaining the subcatchement based on water chain,some programms were developed.

However,after dividing vertical layers and horizontal grids to the watershed,a distributed hydrology model established based on the physical foundation and runoff producing theory could analyse the mutual effect and coupling simulation about surface water and ground water with considering hydraulic connection of different runoff components.

Studies on mountain flood warning system based on distributed hydrological model and its application;

An application study of distributed hydrological model based on the effect of grid aspect;

An application study on distributed hydrological model based on aspect estimation;

Based on the researches about distributed hydrological models in the past two decades, this paper reviews the progress in the following five aspects: 1) the common structure of distributed hydrological models; 2) the relation between distributed hydrological models and GIS and RS.

With the development of Information Technology and Remote Sensing Technology, Distributed Hydrological Models are becoming the trend of Hydrological Models due to their abilities to incarnate the spatial variation of hydrological factors and parameters.

River network and related watershed information directly derived from DEM, is the basis of development and application of distributed hydrological models.

This paper introduces Wetspa model for the flood simulation of Liuxihe River reservoir basin.
