Two wells were drilled northwest (BS-NW) and southwest (BS-SW) of Big Springs in southern Snake Valley in October 2010. The map below shows the wells, the measured water-level elevation above mean sea level in the wells, and the land-surface elevation above mean sea level of Big Springs. Use the three-point method to determine the direction of groundwater flow (3 points) and the slope of the water-level surface or hydraulic gradient (3 points). Report your direction as a compass bearing (e.g., southwest is 225°) and the slope of the hydraulic gradient in feet per mile. 11.481ONAL

Transcribed Image Text:Two wells were drilled northwest (BS-NW) and southwest (BS-SW) of Big Springs in southern
Snake Valley in October 2010. The map below shows the wells, the measured water-level
elevation above mean sea level in the wells, and the land-surface elevation above mean sea level
of Big Springs. Use the three-point method to determine the direction of groundwater flow (3
points) and the slope of the water-level surface or hydraulic gradient (3 points). Report your
direction as a compass bearing (e.g., southwest is 225°) and the slope of the hydraulic gradient in
feet per mile.
