Define the terms transport, deposition and erosion as used in fluvial processes. With the aid of diagrams explain the formation of levees, waterfall and trellis drainage pattern. How can man manage water resources properly?

a)
Transport: The movement of eroded material (sediment) by a river or stream from one location to another. This can occur through processes like solution, suspension, saltation, and traction.
Deposition: The process by which a river or stream lays down or drops the sediment it has been carrying. This typically happens when the river's energy or velocity decreases, such as in slower-moving sections or when it enters a larger body of water.
Erosion: The process by which a river or stream wears away and removes rock and soil from its bed and banks. This occurs through hydraulic action, abrasion, attrition, and solution.
