Rawl infiltration rate
Webb) To analyse the concept of infiltration of water into soils. c) To determine the factors which influence the infiltration rates. 2 METHODOLOGY. The velocity or speed at which water penetrates the soil is referred to as the infiltration rate. The depth (in mm) of the water layer that can infiltrate the soil is commonly used to determine it. http://www.aucklandcity.govt.nz/council/documents/technicalpublications/TP10%20Design%20guideline%20manual%20stormwater%20treatment%20devices%20Chapter%208%20-%202403.pdf
