datum 2--2- 20m 30m 90m CONFINED AQUIFER K = 50 m/day 70m 0 m 15 m datum 1--1 I=400 m 1000m

  1. For datum 1, what are the pressure head, elevation head, and total hydraulic head at well A and well B?

  2. For datum 2, what are the pressure head, elevation head, and total hydraulic head at well A and well B?

Please explain.

Thank you for your help!

Answer #1

Note that pressure head remains constant irrespective of the chosen datum, because it is water column height measured w.r.t. to the chosen point A or B.

CHE) a) Datum I (Read from bottom de ALA, elevation head = 25m. Pressure head = 90-20-25 (Hp) = 45m. so, Total hydraulic head
