WebThe soil type is particularly relevant when it comes to erosion, and stormwater runoff as cohesive soils are less likely to or harder to erode. Hence, cohesive soil particles stick to each other. These soils can be a mix of grain sizes, but are usually primarily fine-grained. WebIt may contain fractions of other types of soils, which will affect its compaction properties. In pure silt or mixed with coarse-grained fractions, there is little cohesion. With a higher clay content, the cohesion will increase. As with all fine-grained soils, silt compaction is extremely dependent on water content. chris crocker and andre marhold
