Discharge at Downstream Water Body of Catchment Solution

Follow our step by step solution on how to calculate Discharge at Downstream Water Body of Catchment?

FIRST Step Consider the formula

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

Next Step Substitute values of Variables

∴

q 1 = (\frac{16m³/s \cdot 4.09m}{2}) + ((\frac{9cm/s}{2 \cdot 4.09m}) \cdot ({12m}^{2} - {5m}^{2}))

Next Step Convert Units

∴

q 1 = (\frac{16m³/s \cdot 4.09m}{2}) + ((\frac{0.09m/s}{2 \cdot 4.09m}) \cdot ({12m}^{2} - {5m}^{2}))

Next Step Prepare to Evaluate

∴

q 1 = (\frac{16 \cdot 4.09}{2}) + ((\frac{0.09}{2 \cdot 4.09}) \cdot (12^{2} - 5^{2}))

Next Step Evaluate

∴

q 1 = 34.0292909535452m³/s

LAST Step Rounding Answer

∴

q 1 = 34.0293m³/s

Natural Recharge

The Natural Recharge is a process by which groundwater is replenished naturally when precipitation infiltrates the ground, moving through the soil and rock layers until it reaches the water table.

Symbol: R

Measurement: Volumetric Flow RateUnit: m³/s

Note: Value can be positive or negative.

Length between Upstream and Downstream

The Length between Upstream and Downstream refers to the horizontal base with a difference in surface elevations.

Symbol: L_stream

Measurement: LengthUnit: m

Note: Value should be greater than 0.

Coefficient of Permeability

The Coefficient of Permeability of soil describes how easily a liquid will move through the soil.

Symbol: K

Measurement: SpeedUnit: cm/s

Note: Value should be greater than 0.

Piezometric Head at Upstream End

The Piezometric Head at Upstream End refers to the specific measurement of liquid pressure above a vertical datum.
