Depression Head when Discharge from Open Well is Considered Solution

STEP 0: Pre-Calculation Summary

Formula Used

Depression Head = Yield from an open well/(Specific Capacity*Area of the Well)
H = Q_Y/(K_s*A)
This formula uses 4 Variables

Variables Used

Depression Head - (Measured in Meter) - Depression Head is the height of the bottom of a well above the datum.
Yield from an open well - (Measured in Cubic Meter per Second) - Yield from an open well is the flow discharge into well under a depression head H.
Specific Capacity - Specific Capacity is the amount of water furnished under a standard unit head.
Area of the Well - (Measured in Square Meter) - Area of the Well is denoted by A symbol.

STEP 1: Convert Input(s) to Base Unit

Yield from an open well: 105 Cubic Meter per Second --> 105 Cubic Meter per Second No Conversion Required
Specific Capacity: 0.75 --> No Conversion Required
Area of the Well: 20 Square Meter --> 20 Square Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

H = Q_Y/(K_s*A) --> 105/(0.75*20)

Evaluating ... ...

H = 7

STEP 3: Convert Result to Output's Unit

7 Meter --> No Conversion Required

FINAL ANSWER

7 Meter <-- Depression Head

(Calculation completed in 00.004 seconds)

Proportionality constant per unit well area of aquifer

Go Proportionality Constant = Area of the Well*((1/Time Interval)*ln(Drawdown at the Start of Recuperation/Drawdown at a Time))

Equation for Time Interval

Go Time Interval = (Area of the Well/Proportionality Constant)*ln(Drawdown at the Start of Recuperation/Drawdown at a Time)

Area of well given time interval

Go Area of the Well = Proportionality Constant*Time Interval/ln(Drawdown at the Start of Recuperation/Drawdown at a Time)

Depression Head when Discharge from Open Well is Considered

Go Depression Head = Yield from an open well/(Specific Capacity*Area of the Well)

Area of well when discharged from open well is considered

Go Area of the Well = Yield from an open well/(Specific Capacity*Depression Head)

Discharge from Open Well under Depression Head

Go Yield from an open well = Specific Capacity*Area of the Well*Depression Head

Specific Capacity per unit Well Area for Discharge from Open Well

Go Specific Capacity = Flow Discharge/(Area of the Well*Depression Head)

Proportionality constant given specific capacity per unit well area of aquifer

Go Proportionality Constant = Area of the Well*Specific Capacity

Area of well given specific capacity per unit well area of aquifer

Go Area of the Well = Proportionality Constant/Specific Capacity

Depression Head when Discharge from Open Well is Considered Formula

Depression Head = Yield from an open well/(Specific Capacity*Area of the Well)
H = Q_Y/(K_s*A)

What is Discharge In Hydrology?

Discharge is the volumetric flow rate of water that is transported through a given cross-sectional area. It includes any suspended solids, dissolved chemicals, or biologic material in addition to the water itself.
