The Godzareh depression (also Gowd-e Zereh) is the lowest part of an inland drainage basin covering large parts of southern Afghanistan and Iran known as the Sistan Basin. The Sistan Basin is as endorheic basin and encompasses a complex system of rivers, shallow lakes, marshes and wetlands as its watershed. At the basin's terminus is the Godzareh depression in Afghanistan and a very small part of Pakistan. The depression is flat and very shallow with fine textured sediment at its bottom. The lowest section of the Godzareh depression is 467 m above sea level. The depression is separated from the main basin by a land barrier so it receives runoff water only when the main tributaries are overflowing.12
In general, a geological depression is a landform that is sunken or lower than the surrounding area. The Godzareh depression is the lowest point in the Sistan Basin in Afghanistan and therefore is the terminus to which all the water flows.3
