State four factors that facilitate deposition in rivers
Answer:
-Reduction of stream gradient: this causes reduction in velocity, thus
the kinetic energy of the river also reduces. The river then deposits some of its load
-Decrease in the volume of water in the river:The capacity to transport its load
reduces hence some of the load is dropped.
-Nature and amount of load: when the velocity of the water is reduced, the river
begins to drop its load in an assorted manner.
-Presence of obstacles in the river channel: the obstacles like rocks, tree trunks may
also act as filters, trapping some of the load being transported.
-Widening of the river channel: when the river bed becomes wider, water spreads out over large surface area. The volume of water per surface area is reduced.
-A river emptying into a calm water body: This causes the velocity of the river to be reduced abruptly hence deposition.
