翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Ravine ： ウィキペディア英語版 Ravine A ravine is a landform narrower than a canyon and is often the product of streamcutting erosion.〔(Definition of "ravine" ) at Merriam-Webster〕 Ravines are typically classified as larger in scale than gullies, although smaller than valleys.〔 ==Definition== A ravine is generally a fluvial slope landform of relatively steep (cross-sectional) sides, on the order of twenty to seventy percent in gradient. Ravines may or may not have active streams flowing along the downslope channel which originally formed them; moreover, often they are characterized by intermittent streams, since their geographic scale may not be sufficiently large to support a perennial watercourse. 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「Ravine」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
