Summary Introduction

The meaning of the term water table and whether its position remains fixed or not.

Introduction:

The water that precipitates from the atmosphere as rain and snow infiltrates the geosphere and becomes groundwater. The amount of precipitation that is soaked into the ground is influenced by climate, land slope, soil and rock type, and vegetation. The water get down into the ground through the soil and through cracks and pores in the rock by the pull of gravity.

Explanation of Solution

The water table is defined as the level of water inside a well of a saturated zone (all rock openings are filled with water) or a boundary that separates the saturated and unsaturated zones, where the saturated zone is present below the unsaturated zone.

The position of the water table is not fixed because the level drifts when water is either lost into the ground or collected into the well. The rise and fall of water table depend on the water emancipated to that of the water rejuvenated into the well

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…
