Variables Used
Radius of Influence - (Measured in Meter) - The radius of influence is the distance from a pumping well to the point where the drawdown, or lowering of the water table, becomes negligible.
Radius of Well - (Measured in Meter) - The radius of well refers to the horizontal distance from the center of the well to its inner wall, essentially the well’s radius.
Discharge by Spherical Flow - (Measured in Cubic Meter per Second) - Discharge by Spherical Flow refers to when water moves radially towards the well in a three-dimensional pattern, typical in confined aquifers or near partially penetrating wells.
Discharge for Fully Penetrating Gravity Well - (Measured in Cubic Meter per Second) - Discharge for Fully Penetrating Gravity Well refers to the volume of water extracted from an unconfined aquifer where the well reaches the entire thickness of the aquifer.
Aquifer Thickness - (Measured in Meter) - Aquifer Thickness (at Midpoint between Equipotential lines) or otherwise is the thickness of aquifer in which the pore spaces of rock forming the aquifer may or may not be with water.
STEP 1: Convert Input(s) to Base Unit

What is Discharge due to Spherical Flow in Well?

Discharge due to spherical flow in a well occurs when water moves radially towards the well in a three-dimensional pattern, typical in confined aquifers or near partially penetrating wells. It is influenced by factors like aquifer properties, well radius, drawdown, and the radius of influence. The discharge rate is determined using equations that account for the changing cross-sectional area of flow and the variation in hydraulic gradient with distance from the well. This flow pattern results in a more complex relationship between discharge and drawdown compared to linear or radial flow.
