Recharge when Maximum Height of Water Table Solution

STEP 0: Pre-Calculation Summary

Formula Used

Natural Recharge = (Maximum Height of Water Table/(Length between tile drain/2))^2*Coefficient of Permeability
R = (h_m/(L/2))^2*K
This formula uses 4 Variables

Variables Used

Natural Recharge - (Measured in Cubic Meter per Second) - Natural Recharge is the replenishment of infiltrating groundwater.
Maximum Height of Water Table - (Measured in Meter) - Maximum Height of Water Table observed.
Length between tile drain - (Measured in Meter) - Length between tile drain considered to establish an approximate expression to the water table profile on a horizontal impervious boundary.
Coefficient of Permeability - (Measured in Meter per Second) - The Coefficient of Permeability of soil describes how easily a liquid will move through the soil.

STEP 1: Convert Input(s) to Base Unit

Maximum Height of Water Table: 40 Meter --> 40 Meter No Conversion Required
Length between tile drain: 6 Meter --> 6 Meter No Conversion Required
Coefficient of Permeability: 9 Centimeter per Second --> 0.09 Meter per Second (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

R = (h_m/(L/2))^2*K --> (40/(6/2))^2*0.09

Evaluating ... ...

R = 16

STEP 3: Convert Result to Output's Unit

16 Cubic Meter per Second --> No Conversion Required

FINAL ANSWER

16 Cubic Meter per Second <-- Natural Recharge

(Calculation completed in 00.004 seconds)

Water table profile neglecting depths of water in drains

Go Water Table Profile = sqrt((Natural Recharge/Coefficient of Permeability)*(Length between tile drain-Flow in 'x' Direction)*Flow in 'x' Direction)

Change in Drawdown given Discharge

Go Change in Drawdown = Discharge*ln(Radial Distance at Observation Well 2/Radial Distance at Observation Well 1)/2*pi*Transmissivity

Natural Recharge given total head

Go Natural Recharge = (Water Table Profile^2*Coefficient of Permeability)/((Length between tile drain-Flow in 'x' Direction)*Flow in 'x' Direction)

Length about discharge per unit width of aquifer

Go Length between upstream and downstream = (Piezometric Head at Upstream End^2-Piezometric Head at Downstream End^2)*Coefficient of Permeability/(2*Discharge)

Discharge per unit width of aquifer is

Go Discharge = ((Piezometric Head at Upstream End^2-Piezometric Head at Downstream End^2)*Coefficient of Permeability)/2*Length between upstream and downstream

Maximum Height of Water Table

Go Maximum Height of Water Table = (Length between tile drain/2)*sqrt(Natural Recharge/Coefficient of Permeability)

Length when Maximum Height of Water Table is Considered

Go Length between tile drain = 2*Maximum Height of Water Table/sqrt(Natural Recharge/Coefficient of Permeability)

Mass Flux Entering Element

Go Mass Flux Entering the element = Water Density*Gross Velocity of Groundwater*Head*Change in 'y' Direction

Recharge when Maximum Height of Water Table

Go Natural Recharge = (Maximum Height of Water Table/(Length between tile drain/2))^2*Coefficient of Permeability

Length when discharge entering per unit length of drain is considered

Go Length between tile drain = Discharge/Natural Recharge

Recharge when Maximum Height of Water Table Formula

Natural Recharge = (Maximum Height of Water Table/(Length between tile drain/2))^2*Coefficient of Permeability
R = (h_m/(L/2))^2*K

What is Recharge?

Recharge is the primary method through which water enters an aquifer. This process usually occurs in the vadose zone below plant roots and, is often expressed as a flux to the water table surface. Groundwater recharge also encompasses water moving away from the water table farther into the saturated zone.

How to Calculate Recharge when Maximum Height of Water Table?

Recharge when Maximum Height of Water Table calculator uses Natural Recharge = (Maximum Height of Water Table/(Length between tile drain/2))^2*Coefficient of Permeability to calculate the Natural Recharge, The recharge when maximum height of water table is defined as the primary method through which water enters an aquifer. Natural Recharge is denoted by R symbol.

How to calculate Recharge when Maximum Height of Water Table using this online calculator? To use this online calculator for Recharge when Maximum Height of Water Table, enter Maximum Height of Water Table (h_m), Length between tile drain (L) & Coefficient of Permeability (K) and hit the calculate button. Here is how the Recharge when Maximum Height of Water Table calculation can be explained with given input values -> 16 = (40/(6/2))^2*0.09.

FAQ
