what is a pothole geography
Potholes. Potholes are cylindrical holes drilled into the bed of a river that vary in depth & diameter from a few centimetres to several metres. Theyâre found in the upper course of a river where it has enough potential energy to erode vertically and its flow is turbulent.In the upper course of a river, its load is large and mainly transported by traction along the river bed.eanders are bends in a river that form as a riverâs sinuosity increases. The sinuosity of a river is a measurement of how much a river varies from a straight line. Itâs a ratio between the channel length and displacement (straight line distance) between two points in the riverâs course:
