The flow is then directed against the opposite bank of the river, which will erode into a more concave shape to accommodate the flow. The bank will still block the flow, causing it to reflect in the other direction. Thus, a bend in the river is created. [7] Rivers may run through low, flat regions on their way to the sea. [12]
The profile of the river water column is made up of three primary actions: erosion, transport, and deposition. Rivers have been described as "the gutters down which run the ruins of continents". [9] Rivers are continuously eroding, transporting, and depositing substrate, sediment, and organic material.
An interdisciplinary unit on rivers is appropriate for elementary or middle school Language Arts, Science and Social Studies. The local river system would be the unifying idea, but the English teacher would link it to Language Arts by studying river vocabulary and teaching students how to do a research report.
Of the 3.5 million miles of rivers in the U.S., 50% are too polluted for fishing, boating or swimming, according to American Rivers, a group focused on protecting and restoring rivers.
Freshwater's primary sources are precipitation and mountain snowmelt. However, rivers typically originate in the highlands, and are slowly created by the erosion of mountain snowmelt into lakes or rivers. Rivers usually flow from their source topographically, and erode as they pass until they reach the base stage of erosion.

Stream gradient may change along the stream course. An average gradient can be defined, known as the relief ratio, which gives the average drop in elevation per unit length of river. [4] The calculation is the difference in elevation between the river's source and the river terminus (confluence or mouth) divided by the total length of the river ...
