What is Confined Aquifer?

A confined aquifer is an aquifer below the land surface that is saturated with water. Layers of impermeable material are both above and below the aquifer, causing it to be under pressure so that when the aquifer is penetrated by a well, the water will rise above the top of the aquifer.

How to Calculate Confined Aquifer Discharge given Coefficient of Transmissibility and Depth of Water?

Confined Aquifer Discharge given Coefficient of Transmissibility and Depth of Water calculator uses Discharge = (2.72*Coefficient of Transmissibility in Enviro. Eng.*(Depth of Water 2-Depth of Water 1))/(log((Radial Distance at Observation Well 2/Radial Distance at Observation Well 1),10)) to calculate the Discharge, The Confined Aquifer Discharge given Coefficient of Transmissibility and Depth of Water formula is defined as the value of confined aquifer discharge when we have prior information of coefficient of transmissibility and depth of water. Discharge is denoted by Q symbol.

How to calculate Confined Aquifer Discharge given Coefficient of Transmissibility and Depth of Water using this online calculator? To use this online calculator for Confined Aquifer Discharge given Coefficient of Transmissibility and Depth of Water, enter Coefficient of Transmissibility in Enviro. Eng. (T_w), Depth of Water 2 (h₂), Depth of Water 1 (h₁), Radial Distance at Observation Well 2 (r₂) & Radial Distance at Observation Well 1 (r₁) and hit the calculate button. Here is how the Confined Aquifer Discharge given Coefficient of Transmissibility and Depth of Water calculation can be explained with given input values -> 1.02266 = (2.72*26.9*(17.8644-17.85))/(log((10/1.07),10)).
