Change in Sediment Supply (Load) - increased sediment supply => deposition - example: downstream from a construction site - example: - decreased sediment supply => erosion, more erosion along banks - example: downstream from a dam (no sediment below the dam) - example: Change in Base Level - elevated base level: decreases gradient => deposition - example: upstream from a dam/reservoir on a stream - example: - dropping base level: increased gradient => erosion - example: Kentucky River, Grand Canyon - example: Change in Discharge - increase discharge =
