What influences water flow?
The volume of stream flow is determined by many factors. Precipitation is of course the primary factor- the more rain or snowmelt, the higher the flow. However, there is usually a lag period between the time a storm reaches it highest intensity and the time the stream reaches it peak flow.
What makes a river flow faster?
Generally a narrower, more circular river channel allows faster flow of water. Broader flat channels tend to slow a river down. 2. Smoother channels also allow faster flow of water; rougher channels slow water flow.
What is the greatest factor controlling streamflow?
Precipitation
Why are watersheds so closely monitored?
Watershed monitoring data can be used for many purposes, such as to determine source(s) of impairment, to provide input for management tools such as models, and to support scientifically-based decisions for preserving or improving the quality of a water resource (Figure 2).
Are healthy watersheds very common?
Are Healthy Watersheds Very Common? Unfortunately not. Healthy watersheds are uncommon, particularly in the eastern U.S. as well as in most other parts of the nation that are urbanized, farmed, or mined. Large tracts of protected wildlands, mostly in the western U.S., are where most healthy watersheds can be found.
What are three key features to a watershed?
The watershed area and the volume of water that drains from it relates directly to the size and flow of the primary stream or water body. Other factors that make each watershed distinctive include its mosaic of land uses, soil types, geology, topography, and climate.
Can watersheds be fed by groundwater?
The boundaries of a surface watershed and groundwater recharge area can, but do not always, coincide. Lakes that appear to have no major inlet are often fed by groundwater. Sometimes humans withdraw too much water from an aquifer, resulting in serious problems.
What is the slope of a watershed?
– Watershed slope reflects the rate of change of elevation with respect to distance along the principal flow path.
How are watersheds named?
The imaginary line that connects those high points is called the watershed divide. Precipitation that falls inside the watershed divide will flow down to the water body (like a river or lake) at the lowest point in that landscape. The watershed is usually named after that water body.
What is another name for watershed?
