Web77 4. INFILTRATION. Infiltration is the process of water entry into a soil from rainfall, or irrigation. Soil water movement (percolation) is the process of water flow from one point to another point within the soil. Infiltration rate is the rate at which the water actually infiltrates through the soil during a storm and it must be equal the infiltration capacities or the … http://www.aucklandcity.govt.nz/council/documents/technicalpublications/TP10%20Design%20guideline%20manual%20stormwater%20treatment%20devices%20Chapter%208%20-%202403.pdf

If two rain drops of total volume 2 mm 3 = 0.000002 m 3 fall per day on one m 2 of soil and are absorbed into the soil, the infiltration rate is 0.000002 m/day. Water entry into soil is caused by matric and gravitational forces.
WebApr 12, 2024 · In total, 486 soil samples were taken from A, B, and C horizons at 174 sampling points and analyzed for soil properties of wilting point, organic matter content, electrical conductivity, pH, and CaCO3 content. Saturated hydraulic conductivity (Ks) and infiltration rate were measured in the field during the sampling. WebThe effectiveness of infiltration systems for nutrient removal is dependent upon the vegetation used in landscaping the system and the phosphorus retention index (PRI) of the soil or infiltration medium. Soil amendment may be necessary to achieve a high rate of phosphorus removal, due to the low PRI of most naturally occurring sands in WA. Table 1.
