The document defines several hydrology terms including: toe, weir, reservoir, river, bank and channel stabilization, and channel stabilization. It explains that a toe is a low dam built across a river, a weir diverts or controls water flow, a reservoir is an artificial lake used to store water often created by a dam, and a river is a natural freshwater watercourse. It also defines river banks and the channel as the stream bed and discusses how channel stabilization can address issues like standing water through regrading and erosion control blankets.
3. A low dam that is built across a river to raise the water level, divert the water, or control its flowWeir
4. Reservoir A reservoir is an artificial lake used to store water. Reservoirs are often created by building reinforced dam, usually out of concrete, earth, rock or a mixture across a river or stream. Once the dam is completed, the stream fills the reservoir.
6. Bank and channel stabilization river banks (stream banks) are channel margins or lateral confines.
7. They are in 2 sides of a stream bed is the channel bottom of a stream, river; the physical confine of the normal water flow.Channel stabilizationBefore: this channel was not graded properly and accumulated standing water. The unattractive rip rap and standing water were major concerns for the neighborhood association. After: the channel was re-graded to proper grade specifications to eliminate standing water. Two types of erosion control blankets were used to stabilize the channel eliminating the need for rip rap.
