ground water table and wells

Unit 15

Groundwater storage, flow, discharge and recharge

This unit covers the role of ground water recharge in hydrometeorology with respect to precipitation, evaporation and runoff as well as the regional water balance.

Goals

The goal of this unit is to quantify groundwater recharge and its relation to other components of the hydrological cycle in the lithosphere.

After successful completion of this unit students will be able to

  1. Explain the groundwater and surface water relations including rivers, lakes and wetlands
  2. Discuss the different stream types
  3. Apply the basic water-balance equation for ground water in the regional water balance
  4. Evaluate ground-water balance components
  5. Explain the role of capillary rise

Students’ tasks

  1. Read  Dingman’s Chapter  Chapter 9.3 to 9.5.4 (included)
  2. Fill out the  questionnaire  prior to Thursday 2359 Alaska time
  3. Work on these Unit 15 Applications  and submit your scanned solutions by  Thursday 2359 Alaska time

Just for fun

Three wells are drilled in form of a triangle with 60 degree angles on each side. The sides are 160 m long. Two wells are oriented north-south direction. The third is east of them. At the northern, southern and eastern most well the piezometric heads are 60, 70, and 80 m, respectively. In which direction does the ground water flow?
