erosion
the removal and transport of rock and soil
recharge zone
the ground zone where water enters an aquifer
old rivers
low gradient and low erosive power; it deposits sediment along its banks
the process by which material is dropped or settled
deposition
rock and soil deposited by streams
alluvium
pollution which comes from one particular point such as a sewer pipe or factory drain
point-source pollution
- Youthful rivers; 2. Mature rivers; 3. Old rivers; 4. rejuvenated rivers
4 river stages
mature rivers
erodes it channel wider than deeper
a rock layer that stores and allows the flow of ground water
aquifer
deposition
the process by which material is dropped or settled
smaller streams or rivers that flow into larger ones
tributaries
the land that is flooded when rivers flood
flood plain
watershed
(drainage basin) land drained by a river system , which includes that main river and its tributaries
point-source pollution
pollution which comes from one particular point such as a sewer pipe or factory drain
the ground zone where water enters an aquifer
recharge zone
water table
where the zone of aeration and saturation meet
erodes it channel wider than deeper
mature rivers
where the zone of aeration and saturation meet
water table
a human-made hole that is deeper than the level of water table; therefore wells fill with groundwater
well
erodes its channel deeper than wide
youthful rivers
when the water table is lower than the level of a cave, the cave is no longer supported by the water underneath; the roof of the cave can hen collapse leaving a circular depression
sinkhole
