侵蝕控制
用法
侵蝕控制用於自然區域,農業設施或城市環境。在城市地區,侵蝕控制通常是地方政府要求的暴雨徑流管理計劃的一部分。控制通常涉及形成物理屏障,例如植被或岩石,以吸收引起侵蝕的風或水的一些能量。
土壤侵蝕是一個自然的過程:沒有它,河流不會曲折和改變過程。然而,改變水文或植被覆蓋的土地管理模式可以增加或減少通道遷移率。在許多地方,無論土地是否由於人類活動而不穩定,人們試圖在一個地方保持一條河。這可以用於環境再生或防止河流改變為人們正在使用的土地。這樣做的一種方法是沿著土地放置亂石或石笼。
數學建模
自20世紀20年代和30年代[1]科學家一直在創造數學模型來理解土壤侵蝕和所產生的沉積物地表徑流的機制,包括阿爾伯特·愛因斯坦應用貝爾定律的早期文章。[2] These models have addressed both gully and sheet erosion. Earliest models were a simple set of linked equations which could be employed by manual calculation. By the 1970s the models had expanded to complex computer models addressing nonpoint source pollution with thousands of lines of computer code.[3] 更複雜的模型能夠解決微觀,土壤粒度分佈和微地形變化的細微差別。
