# Work of a River - **Transportation** refers to the movement of material loosened by erosion and transported to the other place by the action of wind or water. - **Deposition** refers to the laying down of material that has been weathered, eroded and transported by natural processes such as water, wind and ice. ## Agents of Denudation - Erode, transport and deposit sediments at the earth’s surface to produce erosional and depositional landforms. - The four active agents of denudation are **water, wind, waves and glacial ice.** ## Factors Affecting Work of a River - **Speed of Water:** Erosion and transportation are both maximum when velocity is high. - **Volume of Water:** The larger the volume of water, the greater is the power of erosion and transportation. - **Load**: The load of a river, does all the work of erosion and deposition. - **Velocity:** Water carries and deposits sediments and is one of the primary causes of denudation by rivers. - **Angle of Inclination:** The higher the angle of inclination of the river, the greater the force of erosion and the faster the velocity of water. - **Volume of Water:** The larger the volume of water, the greater the force of erosion and the higher the velocity of water. - **Discharge:** The volume of water flowing through a river, is important because it determines the amount of sediment that the river can carry. # Action of a River - **Erosion:** The process of wearing away and transporting rock and soil by natural forces, carried out by a river along its course. - **Transportation:** The process of moving eroded material, such as rocks and soil, downstream by a river. - **Deposition:** The process of dropping eroded material, such as rocks and soil, carried by a river, as the river slows down, especially on the inside bends of the river, forming deposits of sediment.
