Interaction of the Saturated and Unsaturated Soil Moisture Zones. 1. Analytical Solution of the Linearized Richards Equation. 2. The Role of Climate in Shaping the Phreatic Surface

摘要

For agricultural planning, it is useful to know what factors affect the shape and depth of the water table in swampy areas. This study presents a linear model of interactions between the water table and the unsaturated soil moisture zone (which links the saturated water table zone to the land surface). The effects of climate on the water table are also modeled.
