Question
Chapter 9.5, Problem 8A
Summary Introduction
To describe:
The way by which features labeled B on the map can be used to determine the direction of ice flow in a glaciated area.
Introduction:
The word glacier is derived from “glace,” in French the meaning of glace is ice. A huge mass of the ice makes a glacier which moves over land at a very slow rate. Sometimes these are also known as rivers of ice.

44) In periglacial environments, the layer of ground that thaws every summer and freezes every winter is called
A) frost layer
B) permafrost
C) active layer
D) discontinuous permafrost
Use the attached piezometer map to make your own, clean version of the map, and indicate the elevation of the water table at all piezometer locations.
Draw equipotential lines (lines of equal water table elevation) using regular intervals – creating a contoured map of the water table.
Determine the direction of groundwater flow based on the horizontal gradient. Label the areas of recharge and discharge directly on your map.
Flow lines: Draw flow lines on your water table map. The lines should be at right angles to the equipotential lines and extend from the recharge area to the discharge area.
Hydraulic Gradient, Specific Discharge (Darcy Flux), Average Linear Velocity:
Using your water table map, estimate an average hydraulic gradient between two locations, call them locations A and B, one at the eastern-most and a second at the western-most extent of your dataset (note the north arrow on the map).
Calculate the specific discharge, q, between the two locations. For this calculation…
Calculate all the values of table 1:
Q in (L/day)
Q out (L/day)
Residence time (days)
