How does Levees happen

-So the Sediment that has been Eroded upstream is taken down here via Transportation -When the River floods, the Sediment is Split across the Floodplain -When a Flood happens, the River Loses energy. Large Materials is Deposited first on the Sides of the River Banks, with Smaller Materials Further away -After a number of floods, the Sediment builds to add on to the Height of the River Bank. Bigger height equals More Water Capacity, and flooding can be less Likely to happen
