Daily Groundwater Inflow Solution

Follow our step by step solution on how to calculate Daily Groundwater Inflow?

FIRST Step Consider the formula
Vig=Vos+Vog+EL+ΔSL+TL-P-Vis
Next Step Substitute values of Variables
Vig=2m³/s+4m³/s+1958mm+70mm+22mm-50mm-3m³/s
Next Step Convert Units
Vig=2m³/s+4m³/s+1.958m+0.07m+0.022m-0.05m-3m³/s
Next Step Prepare to Evaluate
Vig=2+4+1.958+0.07+0.022-0.05-3
LAST Step Evaluate
Vig=5m³/s

Daily Groundwater Inflow Formula Elements

Variables
Daily Groundwater Inflow
The Daily Groundwater Inflow refers to the amount of groundwater that enters a specific system, such as a sewer system or a water body, on a daily basis.
Symbol: Vig
Measurement: Volumetric Flow RateUnit: m³/s

Daily Surface Outflow
The Daily Surface Outflow refers to the amount of water that exits a system, such as a reservoir, lake, or river, through surface channels on a daily basis.
Symbol: Vos
Measurement: Volumetric Flow RateUnit: m³/s
Note: Value should be greater than 0.
Daily Seepage Outflow
The Daily Seepage Outflow refers to the amount of water that escapes from a system, such as a dam, canal, or reservoir, through porous materials like soil or rock, on a daily basis.
Symbol: Vog
Measurement: Volumetric Flow RateUnit: m³/s
Note: Value should be greater than 0.
Daily Lake Evaporation
The Daily Lake Evaporation refers to the amount of water that evaporates from the surface of a lake over the course of a single day.
