What is transient storage?

Transient storage Transient storage is the part of the water that is moving slower than the most of the water. Things are then stored in the water for some time - in a transient state. It is imporrtant. The more time the water stays in the reach the longer processes like decomposition can occur. So more is decomposed in trannsient storage areas. Can be in pools, backwaters, hyporheric zone and mycrophyte beds
