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 flow rate
|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|
|radius point 1 (r1)||=||0||=||0||meter|
|radius point 2 (r2)||=||0||=||0||meter|
|flow rate (Q)||=||HAS NOT BEEN CALCULATED|
|extraction flow rate|
|pressure head at point 1|
|pressure head at point 2|
|radius at point 1|
|radius at point 2|
