The EnDrain computer program calculates the drainage discharge, hydraulic head, or spacing between parallel subsurface (sub-surface) drains: pipe/tile drains or open ditches, with or without entrance resistance and shows the curve of the watertable (water-table).
The computations are needed for the design of subsurface drainage systems of rainfed or irrigated agricultural land for waterlogging (water logging), watertable (water table) and soil salinity control.
EnDrain can be used for the reclamation (remediation, rehabilitation, restoration) of saline (salty) soils.
