Numerical Simulation for 1-D Water Movement in Unsaturated Soil;

Experimental study on water movement of latosol under drip irrigation;

Under different rainfall intensities,water movement in seashore saline soil was basically similar, and the whole process of water movement was divided into two phases,namely rapidly decreasing phase of water suction and slowly rising phase of water suction.

The characteristic finite element method is applied to discretize the model of 1-Dwater flow in unsaturated soils with variable θ during infiltration and evaporation ,and the characteristic finte element model is obtained.

Rock fragments in the soil may affect the soil structure and the tortuosity of water flow paths, which may further influence the hydrological process, soil water movement and its validity.

Hence,it is awfully necessitated to construct a hydrological model applicable to Hotan Oasis with which,the moisture movement mode can be easier to find and the precious water resour.

In order to study the moisture movement in unsaturated zone,a improved finite element numerical method for solving Richard equation is built and compared with the results in presented literature.

In order to acquire more accuracy of numerical simulation of soil water movement under subsurface irrigation with porous pipe,a two dimension soil-water movement model with boundary of third type was built in this paper.

On the basis of soil-water dynamics, soil-water movement rules in upland field with rainfall are researched, and a one-dimensional vertical unsaturated soil-water movement mathematic model is established.

The rules of the soil-water movement are the base of the development and using for every irrigation technique.
