Scour and erosion resistance in cohesive soils

点击翻译按钮获取中文摘要

The proposed work consists of a number of studies that investigate erosion in cohesive soils. Cohesive soils are those that contain clay and are prevalent in nature. Study of erosion is important because it can affect people in many ways. Bridges can fail if water flows around bridge piers erode away the soil on which they are founded. Dams, culverts, and weirs can be destabilized by erosion of riverbeds downstream of the structures. Erosion of riverbanks can result in loss of property. To predict erosion and attempt to mitigate its negative impacts, engineers must be able to assess under what conditions a particular soil will erode and by how much. For cohesive soils, there are currently no reliable methods to make these assessments.
