11.2

11.2. Stream and River Deposits. Even though flooding along rivers is potentially harmful, many farms are located near rivers. Why do people build along rivers? Floodwaters bring fertile sediment deposits, which enrich the soil. Rivers supply a method of transportation for goods. Deposition.

Alluvial Fans

Alluvial Fans. Composition: siliciclastic , but all types of clasts are possible (usually compositionally immature). Texture : Immature (close to the sediment source), poorly sorted, large-sized clasts are common, clasts can range from angular to rounded.
