Much of Earth’s nutrient cycling takes place in soils. Characteristics of soils control physical, chemical, and biological processes that determine rates of nutrient fluxes, storage, or transformation. As remediation of excess nutrients in stormwater runoff is one function of stormwater Best Management Practices (BMPs), the soil profile constitutes one of the most important factors of BMP design. Variation observed in BMP effectiveness (e.g., why one BMP design works effectively in one place and not another) can often be explained by variations in the soil profile, either through direct means or by a soil’s influence on hydraulics of stormwater flow through …

Flow-biota Interaction and Natural Infrastructure Design

Mangrove forest sustainability hinges upon propagule recruitment and seedling retention. This study evaluates biophysical limitations to mangrove seedling persistence by measuring anchoring force of two mangrove species (Rhizophora mangle and Avicennia germinans). Anchoring force was measured in 362 seedlings via lateral pull-tests administered in mangrove forests of two subtropical estuaries and in laboratory-based experiments. Removal mechanism varied with seedling age: newly-established seedlings failed due to root pull-out while seedlings older than 3 months failed by root breakage. Anchoring force of R. mangle seedlings was consistently and significantly greater than A. germinans (GLM: p = 0.002), however force to …


Determining The Influence Of Emission Pathways On Outgoing Longwave Radiation Over Africa, Thomas Rechtman Aug 2016

Determining The Influence Of Emission Pathways On Outgoing Longwave Radiation Over Africa, Thomas Rechtman

EGS Content

The increase in greenhouse gas (GHG) emissions into the atmosphere has long been know for it effects on the climate. As of yet, the amount of longwave radiation leaving the top of the atmosphere - known as outgoing longwave radiation or OLR - has not been studied in the context of cli- mate change on a regional basis. Using the Coupled Model Intercomparison Project (CMIP5) historical models and Representative Concentration Path- way (RCP) scenarios; along with the National Oceanic and Atmospheric Ad- ministrations (NOAA) OLR satellite data, we determine if observed trends in OLR are forced by GHG emissions or …
