Well Parameter Solution

STEP 0: Pre-Calculation Summary

Formula Used

Well Parameter = (Distance from Pumping Well^2*Storage Coefficient)/(4*Transmissivity*Time Period)
u = (r^2*S)/(4*T*t)
This formula uses 5 Variables

Variables Used

Well Parameter - Well Parameter is the characteristics and property that govern how water levels in a well change over time when water is being pumped.
Distance from Pumping Well - (Measured in Meter) - Distance from Pumping Well is the horizontal distance between a specific point in an aquifer and the location of a pumping well. It influences the behavior of groundwater flow.
Storage Coefficient - Storage Coefficient is the volume of water released from storage per unit decline in hydraulic head in the aquifer, per unit area of the aquifer.
Transmissivity - (Measured in Square Meter per Second) - Transmissivity is the rate at which groundwater flows horizontally through an aquifer or the degree to which a medium allows something, in particular electromagnetic radiation, to pass through it.
Time Period - (Measured in Second) - Time Period is the duration over which groundwater observations, measurements, or modeling simulations are conducted. It can vary from short-term periods to long-term periods.

STEP 1: Convert Input(s) to Base Unit

Distance from Pumping Well: 3 Meter --> 3 Meter No Conversion Required

Well Parameter Formula

LaTeX Go

Well Parameter = (Distance from Pumping Well^2*Storage Coefficient)/(4*Transmissivity*Time Period)
u = (r^2*S)/(4*T*t)

What is Drawdown in Hydrology?

Drawdown is a change in groundwater level due to an applied stress, caused by events such as: Pumping from a well. Pumping from a neighboring well. Intensive water taking from local area. Seasonal declines as recharge rates lower.
