Creating A Stormwater Runoff Model For The City Of Oxford, Mississippi: When It Rains, Where Does That Water Go?, Alexandra Gay Weatherwax
Creating A Stormwater Runoff Model For The City Of Oxford, Mississippi: When It Rains, Where Does That Water Go?, Alexandra Gay Weatherwax
Electronic Theses and Dissertations
The city of Oxford, Mississippi (home of the University of Mississippi) has experienced, in recent years, a rapid growth of urbanization. This rapid increase creates more impervious cover, such as bridges, roads, parking lots, etc., which can cause a stress on the capacity of stream load and causes flooding. To correct this, storm water management is needed in the city. This stormwater runoff model uses data collected from rain gauges, soil data from ssurgo and published soil infiltration rates from a Lafayette County soil survey, impervious cover created from Lidar and Aerial Photography, published evapotranspiration rates, and storm drain locations …
Impact Of Timber Harvest On Mercury Mobilization In A Mixed Pine And Hardwood Forest And Adjacent Lake In Mississippi, Mary Kristen Dickerson
Impact Of Timber Harvest On Mercury Mobilization In A Mixed Pine And Hardwood Forest And Adjacent Lake In Mississippi, Mary Kristen Dickerson
Electronic Theses and Dissertations
With 65% of land area covered in forest, Mississippi is a leader in the timber industry. Whereas forestry provides numerous benefits for humans and wildlife, forest harvest has been hypothesized to increase mercury (Hg) mobilization to aquatic systems. In a forest, Hg mostly accumulates in the upper layer of soil, where associates with organic matter. This top soil is exposed after clear-cutting and thus more susceptible to runoff. Harvest may also change the net balance between Hg methylation and demethylation by microorganisms through changes in redox conditions and addition of carbon sources from decaying logging residues. To better understand the …
