exorheic

Endorheic regions, in contrast to exorheic regions which flow to the ocean in geologically defined patterns, are closed hydrologic systems.

The drainage from an open lake, like that from ordinary rivers, is referred to as exorheic (from the Greek exos, outside and rhein, to flow).

The Ter follows a course of 208 kilometers and drains an area of approximately 3010 km; its basin is described by a dendritic and exorheic drainage pattern.

Apart from the Murray River, it is economically the most important river in Australia, and has the fourth-largest watershed of any exorheic drainage system in Australia.

Even within exorheic basins, there can be "non-contributing", low-lying areas that trap runoff and prevent it from contributing to flows downstream during years of average or below-average runoff.

The Wuqiaoling Range (乌鞘岭), in Tenzhu Tibetan Autonomous County, forms the dividing ridge between the endorheic Shiyang River catchment in the north and the exorheic Yellow River catchment in the south.
