28*Know the practice diagram of water tables and aquifers we did in class* (she asked five questions on it on this quiz)
- AVerdadero
- BFalso
29Darcy's Law represents discharge of groundwater and has the equation Q=KA/(difference in hydraulic head(h)/distance between two wells(l)) What is the discharge of groundwater in a highly dissolved limestone squifer with the following properties
K = 1 m/s
A = 40 m^3
h = 2 m
l = 40 m- Aq = 20 m^3/s
- Bq = 2 m^3/s
- Cq = 40 m^3/s
- Dq = 4 m^3/s
30Groundwater flows from areas of high hydraulic head to areas of low hydraulic head. The greater the difference between hydraulic head elevations, the greater the hydraulic gradient will be between two areas
- AVerdadero

42what is NOT TRUE about sediment pollution
- Afarmlands contribute the most to sediment pollution in water bodies
- Bsediments in a water body reduce the amount of sunlight that can penetrate the water body and reach bottom dwelling plants
- Cif sunlight cannot reach bottom dwelling plants because of high sediment load, photosynthesis cannot occur, and plant populations are reduced
- Dsediment containment ponds increase the amount of sediment runoff into streams
43Which method would NOT reduce surface water pollution?
