WebOct 16, 2024 · Some part of the precipitation that lands on the ground surface infiltrates into the subsurface. The part that continues downward through the soil until it reaches rock material that is saturated is groundwater recharge. Water in the saturated groundwater system moves slowly and may eventually discharge into streams, lakes, and oceans. Webequation for flow through soils becomes: (7.2) g p Total head Pressure head Elevation head z w = + = + ρ Neglect the velocity head in flow through soils. When water flows …
WebAssume that the soil is uniform in the horizontal direction. NOTES: H 2 > H 1, hence water is flowing from H 2 to H 1 (down).
