the slope of a stream or river expressed as a loss in elevation of the stream or river with distance downstream
the area of a river valley next to the channel, which is built of deposoted sediments and is covered with water when the river overflows its banks at flood stage
low ridges on the part of the floodplain inside the meander bend caused by deposition of sediment on the point bar during a flood
a crescent- shaped body of standing water situated in the abandoned channel (oxbow) of a meander after the stream formed a neck cutoff and the ends of the original bend were plugged up by fine sediment.
a major river, fed by a number of fairly large tributaries; the main stream in a river system
an outflowing branch of a river, such as what occurs characteristically on a delta
the area from which all of the rain that falls eventually flows to the same final destination, ussualy in the ocean
the constant circulation of water from sea, through the atmosphere, to the land, and its eventual return to the atmosphere by way of transpiration and eveaporation from the land and evaporation from the sea
a system which material moves from place to place but is not gained or lost from the system
the part of the water that travels over the ground surface without passing beneath the surface
the part of the subsurface water that is in the zone of sauration, including underground streams
the process by which water absorbed by plants, usually through the roots, is emitted into the atmosphere from the plant surface in the form of water vapor
Zone of Aeration
The upper zone which usually isn't completely filled with water, but with rocks and soil too. ( Is about Ground water)
Zone of Saturation
an area beneath the earth's surface which extends downward until all of the open spaces in sediment and rock are completely filled with water
a well drilled through impermeable strata into strata that receive water from a higher altitude so there is pressure to force the water to flow upward
A layer of permeable rock or soil in which the cracks & pores are COMPLETELY FILLED with water
loss of warter from a land area through transpiration of plants and evaporation from the soil and surface water
aquifer in which there is no impermeable layer restricting the upper surface of the zone of saturation
