Detailed explanation-1: -Factors that influence sediment supply Human activities can affect the discharge of water and sediment from a river to the coastal environment in many ways. Deforestation and agriculture, as well as urbanization can increase the erosion of a river basin by as much as an order of magnitude.
Detailed explanation-2: -A sediment budget is the balance between changes in the volume of sediment held within the system and the volume of sediment entering or leaving the system. A positive budget is when there are more inputs than outputs to the system and a negative budget is when outputs are higher than inputs.
Detailed explanation-3: -The impacts from changing levels of erosion and sedimentation threaten fish, invertebrates and aquatic vegetation, in particular. Increased sediment and erosion in rivers, lakes and streams can also affect water quality and availability of drinking water sources.
