Australia's Drainage Basins |
Drainage Basin InformationDrainage Basins form part of the hydrological cycle, (water cycle), but it is an open system. There are twelve drainage basins which can each be sub divided into a total of seventy-seven water regions. These water regions can be divided into two-hundred and forty-five river basins. The Drainage basins are:
· Indian Ocean · Western Plateau · Southwest Coast · Timor Sea · Lake Eyre Basin · South Australian Gulf · Gulf of Carpentaria · Murray-Darling Basin · Tasmania · Northeast Coast · Southeast Coast · Bulloo-Banncannia A drainage basin is an area of land drained by a main river and its tributaries. The reason that a drainage basin is called an open system is because the following process takes place: INPUTS → FLOWS → STORES → FLOWS → STORES → FLOWS → OUTPUTS · Storage is a place such as a lake or pond on the surface or in lakes or rocks underground. · A flow is how and when water is moved around through the system, such as in creeks and rivers. · Tributaries are small channels which drain areas of land. |
