Flow net hydraulic gradient at a point
WebWater does not flow if two points in the water have the same energy or have inadequate head difference. Water may flow even against the gravity if point A is at higher hydraulic head than that of point B. ... Hydraulic gradient throughout the soil is constant so effective stress at that depth z can be given as this. σ’ = zγ’ + iz ... WebThe hydraulic head is measured by determination of the vertical position of the water table in a well relative to a reference surface. Darcy's law says that the discharge rate q is proportional to the gradient in hydrauolic head and the hydraulic conductivity (q = Q/A = …
