- Human illness
The pollution sensitivity of leeches
what is tolerant?
Thermocline
What is the middle layer of stratified lake – water
temp can fluctuate as much as 1 degree C per meter?
pH
What is power of hydrogen or potential of hydrogen?
When crops are planted and tilled along the contours of a hill instead of being plowed straight up and down.
What is contour farming?
According to scientists, stormwater runoff has become the largest source of pollution in
the Bays/Rivers/rivers. list 4 places it comes from.
- city streets
- farms/ag land
- pastures
- suburban parking lots
- lawns & gardens
- golf courses
The pollution sensitivity of caddisflies
What is sensitive?
Percolation
What is the downward movement of water through
the soil profiles?
TMDL
What is total daily maximum load?
A conservation practice that lessens the impact of falling rain and helps hold topsoil, soil or nutrients onto the land.
What is crop residue?
List at least three ways that increased impervious surfaces of urban areas threaten aquatic
resoources
- Rainwater gets prevented from recharging ground water supplies.
- Stormwater runs off in higher amounts and velocities, which scour and erode stream
banks.
- More pollution is washed into waterways.
- Thermal shock to fish can result when summer thunderstorms fall on hot surfaces and
wash into nearby streams

What is less sensitive
Eutrophication
What is the natural aging of a body of water?
SCWQP
What is Soil Conservation Water Quality Plans?
potentiometric surface
What is the imaginary plane where a given reservoir of fluid will "equalize out to" if allowed to flow?
What are six benefits of establishing riparian buffers along stream banks
- To stabilize stream banks and prevent erosion
- To filter runoff from surrounding lands
- To shade streams and control water temperatures
- To provide sources of food and nutrients to aquatic organisms
- To provide habitat for aquatic organisms
- To provide natural travel corridors for wildlife

What is the volumetric flow rate of water in an open channel?
Non-tidal wetlands are inland, freshwater areas not subject to tidal influence. They perform similar ecological functions which are of value to humans. List 5 of these functions
- Fish and wildlife habitat
- Habitat for endangered/rare species
- Erosion control
- Water quality improvement
- Storm water/flood control
- Contribution of organic (plant) material to the food chain
- water reservoirs during dry periods - Recreational opportunities and scenic beauty
