Salinity Management Model: II. 1‐ and 2‐D Applications

A finite element model to simulate salt flow and underdrainage for shallow water table conditions (presented in Part 1) is used to simulate two illustrative cases. The first case involves a one‐dimensional problem in which cotton is growing under conditions typical of the San Joaquin Valley of California. The second case involves a two‐dimensional problem with a tile drain collecting excess water and salts from the root zone. The latter case evaluates the quantity of salts leached from the field through several drain diameters. The model is capable of handling a wide variety of problems that often need scientific assessment, including salinity control and drainage.
