Construction Site Sedimentary Pollution In A Watershed, Imo Okwu
Construction Site Sedimentary Pollution In A Watershed, Imo Okwu
Theses and Dissertations
In the study of sediment pollution on and near a construction site, it is necessary to remember that sediment movement and deposition are part of the natural environment before the intervention of construction. As with many hydrologic problems, most sedimentation problems have visual impacts for relatively short periods, because they are rainstorm-related. Perhaps the most serious sedimentation problem is general deterioration of the total environment, a condition usually not recognized by the public. This research presents an analytical evaluation of five construction sites. The analytical framework categorized the life cycle of construction sites into three stages in order to facilitate …
Comparative Ecology And Conservation Status Of Procambarus (Pennides) Gibbus And Procambarus (Pennides) Versutus In Marion County, Georgia, Joann Chadwick
Comparative Ecology And Conservation Status Of Procambarus (Pennides) Gibbus And Procambarus (Pennides) Versutus In Marion County, Georgia, Joann Chadwick
Theses and Dissertations
Two crayfish species, whose conservation status was of concern, Procambarus (Pennides) gibbus Hobbs and Procambarus (Pennides) versutus Hagen, and one relatively common crayfish, Procambarus (Pennides) spiculifer LeConte were studied at nine creek sites in Marion County, Georgia. Major objectives of the yearlong study were to 1) compare the habitats of these species, looking for environmental differences that might account for their isolated distributions within the county and 2) assess the current conservation status of P. gibbus and P. versutus. Each study site was characterized by a one-time assessment of floodplain width, stream width, water velocity, stream depth and assessment of …
