Rainfall and air temperature variations resulting from climate change are important driving forces to change hydrologic processes in watershed ecosystems. This study investigated the impacts of past and future rainfall and air temperature variations upon water discharge, water outflow (from the watershed outlet), and evaporative loss in the Lower Yazoo River Watershed (LYRW), Mississippi, USA u...

A 2715 ft2 (252 m2), two story, residential home of the style typical of the Gaithersburg, Maryland area was constructed in 2012 to demonstrate technologies for net-zero energy (NZE) homes (or ZEH). The NIST Net-Zero Energy Residential Test Facility (NZERTF) functions as a laboratory to support the development and adoption of cost-effective NZE designs, technologies, construction methods, and b...

Elevated phosphorus (P) loading from the watersheds draining into Lake Erie, particularly agricultural (53%) and urban (43%) sources, is identified as one of main drivers severe eutrophication. In this study, we present a comprehensive evaluation 11 process-based models to characterize water cycle well nutrient fate transport within watershed context, find robust replicable way optimize modelli...

In this paper, the performance of three high pressure HFC refrigerants: R-32, R-41 OA, and R-41 08, is compared to that of R-22. R-32 has excellent thermophysical properties as compared to R-41 OA, R-41 08 and R-22. However, R-32 is a flammable refrigerant while R-41 OA and R-41 OB are non-flammable. The performance of these refrigerants is investigated in a residential heat pump at the test co...

AnnAGNPS (Annualized AGricultural Non-point Source), a continuous simulation and distributed pollution model, is widely applied in evaluating non-point source pollution and watershed management practices. However, the complexity of required input data and modeling procedure keep it from being an efficient modeling tool. An integrated GIS interface was developed to facilitate organizing and prep...
