Influence of Soil Texture, Precipitation Intensity, and Soil Moisture On Stormwater Runoff and Leachate

Soil texture, soil moisture, and precipitation intensity have the potential to influence stormwater runoff and leachate.  To examine these relationships, eighteen lysimeters were constructed  which contain six replications each of three sandy soil compositions representative of those found in newly constructed residential communities in Central Florida.  Three precipitation intensities, ranging from 6.2 to 18.7 mm in 15 min, were chosen to simulate local historical weather data.  The relationships between precipitation rates, soil moisture, and soil texture as they influenced partitioning between stormwater runoff and leachate will be discussed.
