Renaturalized River Channel: Let It Curve Again

A section of a stream that has been restored to its meandering form. The original concrete three-sided channel has been removed, and the waterway has regained its curves: the outer side of the bends is deep and fast-flowing, with deep pools scoured out at the bottom, while the inner side is shallow and slow-flowing, accumulating a sandbar and gravel beach; straight sections have riffles, with fine ripples and sounds on the water surface. The banks on both sides are gently sloped, with varying extents of inundation during water level fluctuations. Avoid: making the waterway a curve of uniform width, having symmetrical depths and slopes on both banks, using concrete or neatly stacked stone revetments, or having a consistent water depth throughout.

一段被改回彎曲的溪流。原本的混凝土三面光渠道被打除,水道重新有了蜿蜒:彎道的外側水深流急、底部被沖刷出深潭,內側水淺流緩、堆積出一片沙洲與礫石灘;直段有淺瀨,水面有細碎的波紋與聲音。兩岸的坡度很緩,水位漲落時淹沒的範圍不同。避免:把水道做成等寬的曲線、讓兩岸的深度與坡度左右對稱、使用混凝土或整齊砌石的護岸、讓水深從頭到尾一致。
