In the Thiessen polygon method, the drainage basin is divided into polygons with the rain gauge in the middle of each polygon assumed to be representative for the rainfall on the area of land included in its polygon. The isohyetal method involves contours of equal precipitation are drawn over the gauges on a map. Management of shared drainage basins is also seen as a way to build lasting peaceful relationships among countries.[14]. Some of these, such as the Great Basin, are not single drainage basins but collections of separate, adjacent closed basins. In hydrology, the drainage basin is a logical unit of focus for studying the movement of water within the hydrological cycle, because the majority of water that discharges from the basin outlet originated as precipitation falling on the basin.
