simple FORTRAN 77 program has implemented three published limit equilibrium slope stability analysis methods for post landslide investigation.

Unsoda v2.0 is a database of unsaturated soil hydraulic properties completed by the U.S. geotechnical office in 1999. It collects the data of soil physical properties such as water characteristic curve, hydraulic conductivity and soil water dispersion, particle size distribution, bulk density and organic matter content of 11 different texture soils from sandy soil to clay.

Saysmosd is a computer program used to predict soil moisture, salinity of groundwater and drainage, depth of groundwater table, and drainage flow in irrigated farmland, using different hydrogeological and aquifer conditions to send different water management options, including groundwater for irrigation, and some crop rotation schedules, where spatial changes are explained by polygonal networks 。
