Evaluation Of Swale Design, David E. Anderson
Evaluation Of Swale Design, David E. Anderson
Retrospective Theses and Dissertations
Swales are designed to infiltrate runoff from intermittent storm events. Present design methodologies have resulted in swales which operate under several conditions; these conditions are soil, vegetation, climatic and geographical location dependent. To attain a swale design which considers and accounts for the important factors under Florida conditions, adequate assessment of rainfall, overland, flow, infiltration and soil moisture must be given priority treatment. Several roadside and residential swales were studied and relationships were drawn for soil moisture, porosity and infiltration rates. A design methodology is included and computer modeling infiltration aids in the design.

Heavy Metals In Floodplains Receiving Highway Bridge Runoff, Elizabeth T. Skene
Retrospective Theses and Dissertations
A study was supported by SUS/STAR to investigate the fate of heavy metals in bridge runoff which are received by surrounding floodplains. Three bridge sites in Central Florida were selected and various locations in each site were sampled. Soil, plant, and water samples were analyzed for Cd, Zn, Cu, Fe, Pb, Ni and Cr. Statistical analysis of results for heavy metal content of plants and soils at control versus bridge sampling areas were conducted. In agreement with other investigators, Pb was found to be a good indicator of highway pollution in soil, plants and water. Possible mechanisms for metal sorption …
