Meanders are a bend in the river that begin to occur in the ____ course of the river but are often fully established in the lower course of the river, on the flat floodplain. On the ____ bend of a meander, the river is always flowing fastest and so there is ____ energy. This results in erosion, particularly ____, as the river crashes into the riverbanks and bed, making the channel deeper and the sides steeper. This creates a ____ On the ____ bend of a meander, the river is always flowing slowly as there is increased ____ with the riverbed and banks, reducing the river’s energy. This results in increased deposition creating a slip-off slope. Due to the processes operating on the inside and outside of the bends, the position of the meander will ____ This is referred to as meander migration. Fast flowing water on the outside of the bend causes the neck of the meander to become increasingly ____ In times of ____ the river’s energy levels will be highest. At this point the river will completely cut through the meander neck. ____ occurs on the inside of the bend, due to slower flow and increased ____ with the riverbed. This deposition clogs the channel, cutting off and isolating the meander loop, creating an oxbow lake. Over time the water in the oxbow lake will ____ leaving behind an a meander scar.
