WebGeotechnical engineers are often contracted to evaluate the ability of subsurface soils to support in-ground disposal of concentrated storm water via infiltration. Infiltration analysis typically consists of exploratory site evaluation, in situ permeability testing, and laboratory analysis of soil samples collected from relevant soil horizons. WebInfiltration practices operate by capturing and temporarily storing stormwater, before allowing it to infiltrate into the underlying soil. The infiltrated water is then partitioned into groundwater recharge, discharge through an underdrain (if applicable), and transpiration. By performing this process, these practices provide two fundamental ...

This test identifies a percolation rate that should be converted to an infiltration rate using the Porchet method. Webtrenches, infiltration basins and underground infiltration systems. Subgrade infiltration tests often are part of a broader geotechnical investigation to evaluate soil characteristics and soil layering at locations proposed for infiltrating stormwater practices that will help the designer understand site and soil suitability or limitations.
