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.

Based on the adsorption-film moisture migration mechanism and the changing in the volume content of the coupled deformations of the phase mediums in saturated frozen soils,the new unfrozen moisture migrating force model in the frozen soil with high confine pressure and the deformation corresponding equations of each phase medium are firstly got with the mass .
