Combined And Synergistic Effects Of Climate Change And Urbanization On Water Quality In The Wolf Bay Watershed, Southern Alabama, Ruoyu Wang
Ruoyu Wang
This study investigated potential changes in flow, total suspended solid (TSS) and nutrient (nitrogen and phosphorous) loadings under future climate change, land use/cover (LULC) change and combined change scenarios in the Wolf Bay watershed, southern Alabama, USA. Four Global Circulation Models (GCMs) under three Special Report Emission Scenarios (SRES) of greenhouse gas were used to assess the future climate change (2016–2040). Three projected LULC maps (2030) were employed to reflect different extents of urbanization in future. The individual, combined and synergistic impacts of LULC and climate change on water quantity/quality were analyzed by the Soil and Water Assessment Tool (SWAT). …
Water Quality Effects Of Cellulosic Biofuel Crops Grown On Marginal Land, Ruoyu Wang
Water Quality Effects Of Cellulosic Biofuel Crops Grown On Marginal Land, Ruoyu Wang
Ruoyu Wang
Since Congress' Energy Independence and Security Act of 2007, there has been increasing interest
in the ability to reach the cellulosic renewable fuel goal of 60.5 billion liters. Cellulosic biofuel crops include
sorghum, switchgrass, Miscanthus, woody crops, and crop residue, among others. Because of concern about
food production on existing highly productive agricultural lands, there is an interest regarding biofuel crop
production on marginal lands. Second generation biofuels, such as perennial grasses and woody plants,
provide an alternative to traditional crops; however, their effects on water quality are not well studied when
grown on marginal lands. Because grasses and woody …
