Western District (Victoria) : ウィキペディア英語版 | Western District (Victoria)
The Western District is an illdefined district, sometimes incorrectly referred to as an economic region, of the Australian state of Victoria. The district is located within parts of the Barwon South West and the Grampians regions; extending from the south-west corner of the state to Ballarat in the east and as far north as Ararat. The district is bounded by the Wimmera district in the north, by the Goldfields district in the east, by Bass Strait and the Southern Ocean in the south, and by the South Australian border in the west. The district is well known for the production of wool. The principal centres of the district are: Warrnambool, Hamilton, Colac, Portland, Casterton, Port Fairy, Camperdown, and Terang. Other cities and towns in or on the edge of the district include: Coleraine, Merino, Heywood, Dunkeld, Penshurst, Macarthur, Koroit, Allansford, Ararat, Willaura, Beaufort, Learmonth, Ballarat, Snake Valley, Skipton, Moyston, Linton, Derrinallum, Lismore, Mortlake, Noorat, Cobden, Timboon, Beeac, Cororooke, Birregurra, Apollo Bay, and Lorne. ==Geology== It consists of a nearly flat volcanic plain created by a number of quite recently active volcanoes, the best known being Mount Eccles, Mount Richmond and Mount Gambier. Whilst some of them (e.g. Mount Richmond) have given rise to cemented pyroclastic rocks that do not produce fertile soils, others have given rise to fertile Andisols that make the district the best grazing land in Australia, as well as highly suitable for the production of vegetable crops. Away from the volcanoes, soils are of moderate to low fertility and many are sandy, supporting heathland flora like the Grampians. Drainage is very poor and most rivers flow only after prolonged periods of steady rain, resulting in remarkably variable flow when the low variability of the climate is taken into account. The major mountain range is the Otway Ranges, which straddle the boundary between the Western District and Port Phillip District.
