Erosion

Erosion along natural steam and riverbanks can increase sediment deposition in stormwater management systems. The accumulation of sediment overtime exerts a stress on stormwater systems, as their overall volume capacity for water becomes reduced.

Soil, sand and minerals washed from land into water, usually after rain. They pile up in reservoirs, rivers and harbors, destroying fish-nesting areas and holes of water animals and cloud the water so that needed sunlight might not reach aquatic plans. Careless farming, mining and building activities will expose sediment materials, allowing them to be washed off the land after rainfalls.
