自20世纪20年代和30年代[1]科学家一直在创造数学模型来理解土壤侵蚀和所产生的沉积物地表径流的机制,包括阿尔伯特·爱因斯坦应用贝尔定律的早期文章。[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] 更复杂的模型能够解决微观,土壤粒度分布和微地形变化的细微差别。
