Interceptor drainage modelling to manage high groundwater table on the Abyek Plain, Iran

High groundwater tables and soil salinity are a serious threat to agricultural areas, especially on the Abyek Plain, Iran. An interceptor drainage system was installed to lower the groundwater head and control soil salinity. Simulation is an appropriate approach to investigate possible groundwater b...
