Date of Defense 2009-11-18 Availability unrestricted AbstractStormwater management facility design is a branch of engineering that demands a full understanding of soil and permeability and how water infiltrates into the ground. With new residential and commercial developments, holding facilities for rainwater are required. Due to the cost associated with purchasing land for holding water, the idea is to make the pond dimensions as small as possible. With this idea, the engineer will need a precise way to determine the rate at which water will infiltrate into the soil.
This research centers on determining how permeability most accurately predicts a stormwater pondís actual infiltration rate. Several estimations for permeability have been evaluated: grain-size correlations, falling head permeameters, double ring infiltrometer tests and single ring infiltrometer tests.
For this research, an existing stormwater facility was chosen. At this location, the field tests were conducted and subsurface samples were taken for laboratory analysis. In addition, to measure the actual field infiltration rate, a staff gage was installed and monitored after a precipitation event. The program MODRET was utilized to determine which of the various estimations of permeability yield an infiltration that most closely resembles that of monitored existing conditions.
