Finding hydraulic gradient
WebThe hydraulic gradient for the flow field on the downstream end of the hydraulic structure is known as exit gradient. To prevent piping failure, the exit gradient should be less than the critical hydraulic gradient. Home ›› Soil Engineering ›› Seepage Analysis ›› Flow Net ›› Hydraulic Parameters WebNov 2, 2010 · The hydrostatic gradient between two points at the water table of an unconfined aquifer is typically defined relative to an elevation datum. The elevations of water levels relative to a datum are denoted zA and zB, while the difference in the elevation of two water levels is denoted zAB. (2.18)

Web(where V is the velocity of the groundwater flow, K is the hydraulic conductivity, and i is the hydraulic gradient). We can apply this equation to the scenario in Figure 14.5. If we assume that the permeability is 0.00001 m/s we get: V = 0.00001 * 0.08 = 0.0000008 m/s. That is equivalent to 0.000048 m/min, 0.0029 m/hour or 0.069 m/day.
Webpoints is the slope of the hydraulic head between those points. For the diagram to the right the difference in head between the two wells is 10 m, and the horizontal distance is 100 m, so the hydraulic gradient is 10/100 = 0.1 Hydraulic gradient is always expressed as a fraction (e.g. 0.1), not as a per cent, or as an angle.
