![]() k = coefficient of permeability, expressed in length per unit time If we define the hydraulic gradient asEquation 6-2: i = Dh L.Dh/L = the hydraulic gradient (dimensionless use of this as the hydraulic gradient is based on Bernoulli’s equation).The flow of water through a soil medium is assumed to follow Darcy’s law: For analysis of major seepage problems, determine permeability and piezometric levels by field observations.Ħ.1.1. For erosion analysis, the surface water flow characteristics, soil type, and slope are needed. In other situations, pressure relief must be incorporated in temporary and permanent structures. Frequently, drawdown of groundwater is necessary for construction. ![]() Seepage pressures are of primary importance in stability analysis and in foundation design and construction. Requirements are given for methods of drainage and pressure relief.Ĭontrol of soil erosion must be considered in all new construction projects. This section covers surface erosion, and analysis of flow quantity and groundwater pressures associated with underseepage. For a complete version of this document click here.
