WebThe floodplain is the area that a river floods onto when it exceeds bank-full capacity. Increased friction as the river breaks its banks reduces the river’s efficiency to transport material resulting in increased levels of deposition. The deposited load on the floodplain is known as alluvium. WebFour major factors that can cause a flood are large amounts of precipitation (or melting) across a region, sudden pulses of precipitation in areas of high runoff, temporary dams made of floating ice (which then break up, releasing impounded water), and failure of human-built dams, causing the sudden escape of water from a reservoir. dead by daylight text chat

WebMeanders reflect the laws of physics. Streams provide a classic case of an open system – allowing mass and energy to flow through and refine its boundaries. For streams managing the flow of water downslope, the opposing needs of minimizing work and uniform distribution of work, or energy, result in compromise.
