Drawdown given Chow's Function Solution

STEP 0: Pre-Calculation Summary

Formula Used

Total Drawdown in Well = Chow's Function*Change in Drawdown
s_t = F_u*Δd
This formula uses 3 Variables

Variables Used

Total Drawdown in Well - (Measured in Meter) - Total Drawdown in Well is defined as the reduction in hydraulic head observed at a well in an aquifer, typically due to pumping a well as part of an aquifer test or well test.
Chow's Function - Chow's Function is a constant given by chow.
Change in Drawdown - (Measured in Meter) - Change in Drawdown is defined as the difference at the two wells.

STEP 1: Convert Input(s) to Base Unit

Chow's Function: 3.83 --> No Conversion Required
Change in Drawdown: 0.23 Meter --> 0.23 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

s_t = F_u*Δd --> 3.83*0.23

Evaluating ... ...

s_t = 0.8809

What is Drawdown?

A drawdown is a peak-to-trough decline during a specific period for an investment, trading account, or fund. A drawdown is usually quoted as the percentage between the peak and the subsequent trough.
