Abstract
AbstractInfiltration basins are commonly utilized to reduce or eliminate stormwater runoff and are commonly located on coarse soils due to relatively high infiltration rates. Forty infiltration basins in Florida were included in this field study to evaluate whether basin infiltration rates varied significantly from their designed infiltration rates. Basins were located among Leon, Alachua, and Marion counties in Florida, while watershed land uses were equally divided between Florida Department of Transportation and residential developments. Generally, six test sites within each basin were selected for infiltration rate measurement by double-ring infiltrometer (DRI). Also, a soil boring was collected from each test site for analyses, including soil texture, bulk density, and organic matter content. Infiltration rates were log-transformed and statistical analysis was used to determine if DRI measurements were significantly different from design rates. Basin soil textures were well distributed between sand, ...
