Exercise 4
Two piezometers located near an inland saline lake are screened 60 mbls and are 200 m apart as shown in the image below. The land surface is at 100 masl and the aquifer has a hydraulic conductivity of 10 m d–1.
Measured hydraulic heads and densities are shown in the following table.
| Piezometer | Hydraulic head (masl) | Density (kg/m3) |
| 1 | 100.4 | 1010 |
| 2 | 100 | 1020 |
Questions:
- What is the direction of groundwater flow?
- What is the specific discharge?
