    • Advances in Watershed Management: Modeling, Monitoring, and Assessment 

      Benham, B. L.; Yagow, G.; Chaubey, I.; Douglas-Mankin, K. R. (American Society of Agricultural and Biological Engineers, 2011)
      This article introduces a special collection of nine articles that address a wide range of topics all related to improving the application of watershed management planning. The articles are grouped into two broadly defined ...
    • Die-off of E. coli and enterococci in dairy cowpats 

      Soupir, M. L.; Mostaghimi, Saied; Lou, J. (American Society of Agricultural and Biological Engineers, 2008)
      E. coli and enterococci re-growth and decay patterns in cowpats applied to pasturelands were monitored during the spring, summer fall, and winter First-order approximations were used to determine die-off rate coefficients ...
    • Effects of forest harvesting best management practices on surface water quality in the Virginia coastal plain 

      Wynn, T. M.; Mostaghimi, Saied; Frazee, J. W.; McClellan, P. W.; Shaffer, R. M.; Aust, W. Michael (American Society of Agricultural and Biological Engineers, 2000)
      Three small watersheds located in Westmoreland County, Virginia, were monitored to evaluate the impact of forest clearcutting on surface water quality and to evaluate the effectiveness of forestry best management practices ...
    • Environmental Best Management Practices for Virginia's Golf Courses 

      Schoenholtz, Stephen Hanley; Goatley, Michael; Ervin, Erik; Hodges, Steve; Hipkins, Perry Lloyd, 1945-; McCall, David Scott; Askew, Shawn; Youngman, Rod R.; Hipkins, Patricia A.; Grisso, Robert D. (Robert Dwight), 1956-; Muckley, Glenn; George, Lester; Ballard, Mike; Roadley, Chuck; Lajoie, Matt; Rodriguez, Mark; Habel, Robert; Sexton, Tim (Virginia Cooperative Extension, 2013-02-27)
      Provides recommendations for golf courses in the Commonwealth that emphasize water quality protection and have been specifically adapted for courses in Virginia using the results of current research, the experience of golf ...
    • Facilitated iron reduction as a possible means of rejuvenating phosphorus removal performance of filtration substrates 

      Rosenquist, S. E.; Levy, C. L.; Sell, S. T.; Hession, W. Cully; Eick, M. J.; Vaughan, D. H. (American Society of Agricultural and Biological Engineers, 2011)
      In order to mitigate nutrient pollution in surface runoff more sustainably, the finite capacity for phosphorus (P) sequestration in best management practices (BMP) that rely heavily on sorption processes must be addressed. ...
    • Manure and wastewater management systems for open lot dairy operations 

      Sweeten, J. M.; Wolfe, M. L. (American Society of Agricultural and Biological Engineers, 1994)
      Dairy industry expansion using open lot designs has impacted water quality and groundwater usage in parts of Central Texas. Field research was conducted at commercial dairy farms in Erath County, Texas, to develop improved ...
    • Modeling bacteria fate and transport in watersheds to support TMDLs 

      Benham, B. L.; Baffaut, C.; Zeckoski, R. W.; Mankin, K. R.; Pachepsky, Y. A.; Sadeghi, A. A.; Brannan, Kevin M.; Soupir, M. L.; Habersack, M. J. (American Society of Agricultural and Biological Engineers, 2006)
      Fecal contamination of surface waters is a critical water-quality issue, leading to human illnesses and deaths. Total Maximum Daily Loads (TMDLs), which set pollutant limits, are being developed to address fecal bacteria ...
    • Sediment and nutrient modeling for TMDL development and implementation 

      Borah, D. K.; Yagow, G.; Saleh, A.; Barnes, P. L.; Rosenthal, W.; Krug, E. C.; Hauck, L. M. (American Society of Agricultural and Biological Engineers, 2006)
      At present, there are over 34,000 impaired waters and over 58,000 associated impairments officially listed in the U.S. Nutrients and sediment are two of the most common pollutants included in the list. States are required ...
    • Use of biological indicators in TMDL assessment and implementation 

      Yagow, G.; Wilson, B.; Srivastava, P.; Obropta, C. C. (American Society of Agricultural and Biological Engineers, 2006)
      Most states in the U.S. have a general water quality standard intended to protect water from all potential pollutants not specifically named or identified in other standards. Biological indicators are used, in part, to ...
