watertable

Residue separate horizon can effectively prevent groundwater and salt up in high watertable saline area.

The multicyclic tectonic movement, multiperiodic raising and falling of lake watertable have provided the basis of materials for the forming of each kind of lithologic gas pool.

Based on the natural flow character of groundwater and the principle of flow simulation, a digital watertable model was built by the method of inverse distance weights in the GIS environment.
