It is the height of the free surface of water above a given point beneath the surface. [4] Pumping level is the level of water in the well during pumping. [8] Specific capacity is the well yield per unit of drawdown. [8] Static level is the level of water in the well when no water is being removed from the well by pumping. [8]
[13] [14] [15] GSSHA is widely used in the U.S. for research and analysis by U.S. Army Corps of Engineers districts and larger consulting companies to compute flow, water levels, distributed erosion, and sediment delivery in complex engineering designs. A distributed nutrient and contaminant fate and transport component is undergoing testing.
It supports river hydraulic and storm drain models, lumped parameter, regression, 2D hydrologic modeling of watersheds, and can be used to model both water quantity and water quality. As of January 2017 [update] , supported models include HEC-1 , HEC-RAS , HEC-HMS , TR-20 , TR-55 , NFF , Rational , MODRAT , HSPF , CE-QUAL-W2 , GSSHA , SMPDBK ...

Dynamic wave routing can account for channel storage, backwater, entrance/exit losses, flow reversal, and pressurized flow. Because it couples together the solution for both water levels at nodes and flow in conduits it can be applied to any general network layout, even those containing multiple downstream diversions and loops.
In fluid dynamics, total dynamic head (TDH) is the work to be done by a pump, per unit weight, per unit volume of fluid.TDH is the total amount of system pressure, measured in feet, where water can flow through a system before gravity takes over, and is essential for pump specification.
Water level, also known as gauge height or stage, is the elevation of the free surface of a sea, stream, lake or reservoir relative to a specified vertical datum. [ 1 ] See also
