Depression Head in Well given Pumping Stopped with Discharge Solution

STEP 0: Pre-Calculation Summary

Formula Used

Depression Head = Depression Head in Well 2*10^((Discharge in Well*Time Interval)/(Cross Sectional Area*Constant Depression Head*2.303))
h_d = h_w2*10^((Q*Δ_t)/(A_cs*H'*2.303))
This formula uses 6 Variables

Variables Used

Depression Head - (Measured in Meter) - Depression Head is the difference of level of waters table and the water level in the well when pumping stopped.
Depression Head in Well 2 - (Measured in Meter) - Depression Head in Well 2 is depression head in the well at a time T after the pumping stopped.
Discharge in Well - (Measured in Cubic Meter per Second) - Discharge in Well is the rate of flow of a liquid in well.
Time Interval - (Measured in Second) - Time Interval is the amount of time required for the total change in concentration.
Cross Sectional Area - (Measured in Square Meter) - Cross Sectional Area is the area of a two-dimensional shape that is obtained when a three-dimensional shape is sliced perpendicular to some specified axis at a point.
Constant Depression Head - Constant Depression Head is the constant value of head in the well.

STEP 1: Convert Input(s) to Base Unit

Depression Head in Well 2: 10 Meter --> 10 Meter No Conversion Required
Discharge in Well: 0.99 Cubic Meter per Second --> 0.99 Cubic Meter per Second No Conversion Required
Time Interval: 1.01 Second --> 1.01 Second No Conversion Required
Cross Sectional Area: 20 Square Meter --> 20 Square Meter No Conversion Required
Constant Depression Head: 0.038 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

h_d = h_w2*10^((Q*Δ_t)/(A_cs*H'*2.303)) --> 10*10^((0.99*1.01)/(20*0.038*2.303))

Evaluating ... ...

h_d = 37.2631893865673

STEP 3: Convert Result to Output's Unit

37.2631893865673 Meter --> No Conversion Required

FINAL ANSWER

37.2631893865673 ≈ 37.26319 Meter <-- Depression Head

What is Discharge?

Discharge in the context of wells, rivers, or any hydraulic system refers to the volume of water flowing out of a particular source over a given period of time. It’s often used to describe the amount of water being produced or released from a well, river, or drainage system. Discharge is a critical factor in evaluating the capacity of a well or river to provide water. For example, higher discharge rates in a well indicate higher water yield, which is important for assessing its productivity and sustainability.
