“…This study is based on stream discharge measurements obtained during similar base-flow conditions during July 25-28, 2005, andon May 4, 2006. During these periods, the base-flow discharge provided by ground-water outflow to streams in the study area was approximately half of the longterm mean annual ground-water recharge rate estimated by Kozar and Mathes (2001).…”

“…Streamflow at USGS gaging station 01616500 Opequon Creek near Martinsburg averaged 100 ft 3 /s (44,900 gal/min) on May 4, 2006, a value that is approximately equivalent to the 45-percent duration of summer flows reported by Wiley (2006) It was not possible to define all of the hydrologic factors affecting the results of this study. Pumps were noted as running July 25-28, 2005, at Kilmer Spring and at Lefevre Spring, but outflow measurements were not adjusted because the amount of diversion was unknown (Evaldi and Paybins, 2006). Other unknown diversions or interbasin transfers of water could have occurred during the study.…”

“…Discharge information was obtained during July 25-28, 2005, at 69 stream sites, 31 springs, and 1 wastewater-treatment-plant outfall in the Opequon Creek Watershed (Evaldi and Paybins, 2006). The wastewater-treatment-plant outfall measurement and 17 of the stream measurements were used in this study.…”

“…Discharges of streams and a wastewater-treatment-plant outfall in the Opequon Creek Watershed in Berkeley County were measured during base-flow conditions in July 25-28, 2005 (Evaldi andPaybins, 2006). In order to extend the study area to describe the base flow of streams throughout the county, additional stream-discharge measurements were made during base-flow conditions on May 4, 2006.…”

Base-flow yields at approximately 50 percent of the annual mean groundwater recharge rate were estimated for watersheds in the Berkeley County area, W.Va. These baseflow yields were determined from two sets of discharge measurements made July 25-28, 2005, and May 4, 2006. Two sections of channel along Opequon Creek had net flow losses that are expressed as negative base-flow watershed yields; these and other base-flow watershed yields in the eastern half of the study area ranged from-940 to 2,280 gallons per day per acre ((gal/d)/acre) and averaged 395 (gal/d)/acre. The base-flow yields for watersheds in the western half of the study area ranged from 275 to 482 (gal/d)/acre and averaged 376 (gal/d)/acre.

A spatial optimization approach to watershed water quality management: A case of the Opequon Watershed

The Opequon Creek watershed is located in northern VA and the eastern panhandle of WV. Currently, the main creeks in the watershed do not meet VA or WV state water quality standards for recreational uses and aquatic life. In both states, the creeks are listed as impaired due to high levels of nutrients, bacteria, benthic and biologic impairment. The Opequon Creek is part of the upper Potomac River watershed, and ultimately impacts water quality in the Chesapeake Bay watershed. The main aim of this study was to develop a methodology that can be used to reduce nutrient loadings entering the bay area and improve water quality in Opequon watershed by implementing four innovative agricultural BMPs. The study develops an integrated approach to nutrient reduction incorporating three models involving water quality modeling, nutrient fate and transportation and an optimization model to recommend a least cost strategy for nutrient reduction. Special thanks to my advisory committee members Drs Gerard D'Souza, Tanya Borisova and Calvin Masilela for providing me with useful comments, suggestions, and the stimulating discussions we had. I would like to express my deepest thanks to Dr. Tanya Borisova for her invaluable comments on both theoretical and empirical areas of my research. I am thankful to Drs. Gerard D'Souza and Tanya Borisova for teaching Quantitative Methods and guidance in optimization techniques and model development. My acknowledgements to Professor Calvin O. Masilela, external member of my advisory committee, mentor and colleague, for his counsel, encouragement, undying support and help during all the stages of my Ph.D. study. Thank you so much in believing in me. Above all, this work would not have been possible without the undying support, sacrifice and encouragement of my wife Abigail. Thank you so much. I am also thankful to my son Anesu and my daughter Bethany for their patience and moral support throughout my study. My sincere gratitude is expressed towards Tom Basden for providing research funding through the Mid-Atlantic Water Program. Lastly, I am heavily indebted to all my friends during the Ph.D. program. Thank you for your help, support and encouragement. May God bless you all. CHAPTER 1: INTRODUCTION 1.0. INTRODUCTION Water provides the basis of life on Earth and the foundation of all civilizations. Increasing global demand for fresh water supplies coupled with limited availability of clean water and an uneven spatial plus temporal distribution of water supplies often leads social and economic problems. These problems include: struggles over access and use of limited water resources, lack of access to safe drinking water and inadequate sanitation, low economic growth and agricultural productivity, (Shah, 2007; UNDP, 2006; NRC, 2000). Thus, a major management challenge for water resources is maintaining water quality to meet human, plant and animal life (Cosgrove and Rijsberman, 2000). Increasing human populations and economic activities have continued to degrade existing water quality (Goolsby et a...
