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]
Passau, Germany, sometimes called the Dreiflüssestadt (City of Three Rivers), is the site of a triple confluence, described thus in a guidebook: "from the north the little Ilz sluices brackish water down from the peat-rich Bavarian Forest, meeting the cloudy brown of the Danube as it flows from the west and the pale snow-melt jade of the Inn ...
Gully – Landform created by running water and/or mass movement eroding sharply into soil; Island – Piece of subcontinental land surrounded by water; Levee § Natural levees; Meander – One of a series of curves in a channel of a matured stream; Oxbow lake – U-shaped lake or pool left by an ancient river meander
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.
In geography and geology, fluvial sediment processes or fluvial sediment transport are associated with rivers and streams and the deposits and landforms created by sediments. It can result in the formation of ripples and dunes , in fractal -shaped patterns of erosion, in complex patterns of natural river systems, and in the development of ...
The basin of a river is the expanse of country bounded by a watershed (called a "divide" in North America) over which rainfall flows down towards the river traversing the lowest part of the valley, whereas the rain falling on the far slope of the watershed flows away to another river draining an adjacent basin. River basins vary in extent ...

The dead zone at the outlet of the Mississippi River is a consequence of nitrates from fertilizer being carried off agricultural fields and funnelled down the river system to the Gulf of Mexico. Runoff also plays a part in the carbon cycle , again through the transport of eroded rock and soil.
