WebThe hydraulic gradient is the driving force that causes groundwater to move in the direction of maximum decreasing total head. It is generally expressed in consistent units, such as feet per foot. For example, if the difference in water level in two wells 1000 feet apart is 2 feet, the gradient is 2/1000 or 0.002 ( Fig. 3-12 ).

These stresses are larger for larger velocity gradients. The development of a boundary layer in a fluid passing over a stationary flat plate is illustrated below.

WebMar 2, 2024 · The slope (gradient) of the energy line is a measure of the friction slope or rate of energy head loss due to friction. Under uniform flow, the energy line is parallel to the water surface and to the streambed. For flow to occur in a channel, the total head or energy line must slope negatively (downward) in the direction of flow.
