Endorheic basin:
An endorheic basin is a closed drainage that retains water and does not allow for overflow to other external bodies such as the rivers and or oceans. The endorheic basin may form either permanent or seasonal lakes or swamps that equilibrate only through evaporation. The basin is also commonly referred to as internal drainage system or a closed basin. However, under normal circumstances, the water that accumulates in the drainage basin flows out through rivers or streams or by underground diffusion through permeable rocks and finally ends up in the ocean. This scenario is not common in the endorheic Basin since water that flows into the basin cannot flow out and may only leave the drainage through evaporation or seep into the ground. [WorldAtlas]
