Impact of best management practices on water quality in the Nomini Creek Watershed
The Nomini Creek Watershed project was initiated in 1985 as Virginia's action in dealing with the water quality problems of the Chesapeake Bay. Nomini Creek was selected because it was an agricultural watershed with few best management practices in place at the beginning of the study and was a …

Watershed nonpoint source management system: a geographic information system approach
… Holston River (MFHR) drainage basin, Owl Run and Nomini Creek watersheds in Virginia. WATNPS utilizes annual screening models for the prediction of pollutant yields. Overland delivery ratio, phosphorus yield, and animal waste models were modified for use in the system. In-stream delivery ratio, …

Modeling Spatial Variability of Field-Scale Solute Transport in the Vadose Zone
… Plain of Georgia and a 0.05-ha field plot in Nomini Creek watershed in Virginia. Results from the rate-based Opus-SF and capacity-based GLEAMS-SF were compared to determine if there were significant differences in their predictions. In the stochastic approach, the heterogeneous field is …

SET-WET: A Wetland Simulation Model to Optimize NPS Pollution Control
… The model was applied to a subwatershed in the Nomini Creek watershed located in Virginia. Two year simulations were completed for five separate wetland designs, with reductions in percentage of BOD5 (4%-45%), TSS (85%-100%), total nitrogen (42%-56%), and total phosphorous (38%-57%) comparable …

Assessment of groundwater vulnerability to pesticide contamination in Albemarle and Louisa counties, Virginia
… years of groundwater monitoring data from the Nomini Creek watershed study. Two types of rankings were made, one using the AF model simulation results, while the other ranking was based on the frequency of detection of pesticides in the Nomini Creek watershed. A comparison of the rankings …

A comprehensive modeling approach for BMP impact assessment considering surface and ground water interaction
… Owl Run watershed (1140 ha) and QN2 in the Nomini Creek watershed (216 ha), to evaluate the model components and its performance in predicting runoff, sediment yield, and pesticide load. DANSAT performed well in predicting total runoff and temporal variations in surface runoff for both …

Impacts of Best Management Practices on Nitrogen Discharge From a Virginia Coastal Plain Watershed
… data (1986-1996) collected at the Nomini Creek (NC) watershed were used. Field (Field-N) and watershed (Watershed-N) scale N models were developed for computing the N balances. BMPs evaluated in this study included no-till corn and split N application. The role of atmospheric N …
