Abstract
Due to extreme arid conditions in Afghanistan, it is critical to conduct research by modeling groundwater features. The studies conducted in Nimroz province on the groundwater flow directions, aquifer types, inflow, outflow, evaporation, and geology of the region are presented. Samples were collected from each profile and transported to our laboratory for characterization. The objective was to identify parameters in different locations of Nimroz and Zarang, for potential use as a water resource, since no such data exists due to years of conflict in the region. From this study, we assess the features of lithology, such as silty sand, clay with gravel, sandy silt, gravel, boulder, and clay with gravel, in addition to the groundwater quality, which is saline, due to evaporation in this region. Generally, the thickness of aquifers is about 5-25m, and the groundwater has evaporated to 5-10m depth with an annual precipitation of about 50-100 mm. It is further observed that the groundwater direction is from east to west. The results suggest that the modeling can be used for other regions.
