Equation of Head for Unconfined Aquifer on Horizontal Impervious Base Solution

Follow our step by step solution on how to calculate Equation of Head for Unconfined Aquifer on Horizontal Impervious Base?

FIRST Step Consider the formula

h = \sqrt{(\frac{- R \cdot x^{2}}{K}) - ((\frac{{h o}^{2} - {h 1}^{2} - (\frac{R \cdot {L stream}^{2}}{K})}{L stream}) \cdot x) + {h o}^{2}}

Next Step Substitute values of Variables

∴

h = \sqrt{(\frac{- 16m³/s \cdot {2m³/s}^{2}}{9cm/s}) - ((\frac{{12m}^{2} - {5m}^{2} - (\frac{16m³/s \cdot {4.09m}^{2}}{9cm/s})}{4.09m}) \cdot 2m³/s) + {12m}^{2}}

Next Step Convert Units

∴

h = \sqrt{(\frac{- 16m³/s \cdot {2m³/s}^{2}}{0.09m/s}) - ((\frac{{12m}^{2} - {5m}^{2} - (\frac{16m³/s \cdot {4.09m}^{2}}{0.09m/s})}{4.09m}) \cdot 2m³/s) + {12m}^{2}}

Next Step Prepare to Evaluate

∴

h = \sqrt{(\frac{- 16 \cdot 2^{2}}{0.09}) - ((\frac{12^{2} - 5^{2} - (\frac{16 \cdot {4.09}^{2}}{0.09})}{4.09}) \cdot 2) + 12^{2}}

Next Step Evaluate

∴

h = 28.790977789312m

LAST Step Rounding Answer

∴

h = 28.791m
