Unconfined Aquifer Well Design Calculator
Fluid Mechanics Hydraulics Hydrology
The following equation uses Darcy's equation with pumping occurring at the center of a cylinder. This equation can be utilized to determine the cone of depression and well drawdown in an unconfined aquifer.
Solving for radius at point 2.
Inputs:
Conversions:
| radius point 1 (r1) | = | 0 | = | 0 | meter | |
| coefficient of permeability (K) | = | 0 | = | 0 | meter/day | |
| pressure head at point 1 (h1) | = | 0 | = | 0 | meter | |
| pressure head at point 2 (h2) | = | 0 | = | 0 | meter | |
| flow rate (Q) | = | 0 | = | 0 | meter^3/day |
Solution:
| radius point 2 (r2) | = | HAS NOT BEEN CALCULATED |
