The Frankland River is a river in the great southern region of Western Australia. The Frankland River is the largest river by volume in the region and the eighth largest in the state.〔(【引用サイトリンク】title= Waterways WA - Strategies for Management to WA waterways )〕 ==Location and features== Mt Frankland was named in December 1829 by naval ship's surgeon Thomas Braidwood Wilson after the Surveyor General of Van Dieman’s Land George Frankland. Wilson explored the area in company with the Noongar Mokare from King George Sound, John Kent (officer in charge of the Commissariat at Frederick Town, King George Sound), two convicts and Private William Gough of the 39th Regiment, while his ship the ''Governor Phillip'' was being repaired at King George Sound.〔 〕〔 〕 The river was sighted by Captain Thomas Bannister in January 1831, and was named by Governor James Stirling when Bannister reported its existence to him.〔 〕 Stirling's choice was influenced by Wilson's naming of Mt Frankland. The Frankland was apparently previously known by sealers as the Deep River.〔 The Gordon River, a tributary of the Frankland River has its source south-west of the town of Broomehill. The other two smaller tributaries are Towerlup Brook and Ornabullup Creek. The Walpole, the Deep and the Frankland all flow into the Nornalup Inlet west of Walpole. 85% of the Frankland River's catchment, mostly about the rainfall isohyet, is cleared for agriculture. The main land uses are cereal cropping and sheep grazing, with minor dairy farming, agroforestry, viticulture and olive farming. Salinity has increased in the river system with average values of 2 ppt in the 1970s to 1980s to 30 ppt since 2000. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Frankland River」の詳細全文を読む スポンサード リンク
