A Watershed Scale Evaluation Of Selected Second Generation Biofeedstocks On Water Quality, Gurdeep Singh Dec 2012

A Watershed Scale Evaluation Of Selected Second Generation Biofeedstocks On Water Quality, Gurdeep Singh

Graduate Theses and Dissertations

This study compares a novel simulation approach to the conventional Soil and Water Assessment Tool (SWAT) modeler's approach for targeting biofuel crop production on marginal lands. In conventional SWAT modeling approach, non-spatial definition of hydrological response units (HRUs) results in the simulation of biofuel crops on both marginal and non-marginal land. This study provides an alternative approach in which a marginal-land raster was integrated into the land use and land cover (LULC) raster in such a way that the land uses were divided into marginal and non-marginal components. This modified LULC was used for model setup which resulted in marginal …


Nutrient Dynamics In Stormwater Runoff From Green Roofs With Varying Substrate, John Michael Fohner May 2012

Nutrient Dynamics In Stormwater Runoff From Green Roofs With Varying Substrate, John Michael Fohner

Graduate Theses and Dissertations

One major concern with urban development is the increasing amount of stormwater runoff from large expanses of impervious surfaces. These impervious surfaces reduce the ability of stormwater to infiltrate into the soil and eventually groundwater, which leads to greater amounts of surface runoff. Green technology serves as a viable solution to many of the environmental problems presented by modern development. Fifteen mock, extensive green roofs were built in the fall of 2008 at the Watershed Research and Education Center in Fayetteville, Arkansas. The goals of this project were to (1) measure the amount of stormwater runoff from varying treatments and …


Surface Water Characteristics Of The Weaber Plain And Lower Keep River Catchments: Data Review And Preliminary Results, D L. Bennett, Richard J. George Dr Dec 2011

Surface Water Characteristics Of The Weaber Plain And Lower Keep River Catchments: Data Review And Preliminary Results, D L. Bennett, Richard J. George Dr

Resource management technical reports

In 2008, the Ord Irrigation Expansion Project was approved by the Western Australian Government to develop irrigated agriculture on the Weaber Plain.

An important concern is the effect the Weaber Plain agricultural development may have on the water quality of the downstream Border Creek and Keep River

This report assembles and reviews all available physico-chemical water quality data for the lower Keep River and Border Creek systems and presents data from the initial year of a targeted baseline monitoring program (June 2010 – June 2013).

Assessment Of Row Crop, Alfalfa, And Pasture Field Practices On Groundwater Quality In An Upland Bedrock Setting, Henderson County, Kentucky: Report Of Soil- And Water-Quality Data, E. Glynn Beck, James S. Dinger, John H. Grove, Eugenia Pena-Yewtukhiw Jan 2010

Assessment Of Row Crop, Alfalfa, And Pasture Field Practices On Groundwater Quality In An Upland Bedrock Setting, Henderson County, Kentucky: Report Of Soil- And Water-Quality Data, E. Glynn Beck, James S. Dinger, John H. Grove, Eugenia Pena-Yewtukhiw

Information Circular--KGS

An assessment of how present agricultural practices have influenced shallow groundwater and soil quality was conducted on a 540-acre farm in north-central Henderson County. Groundwater- and soil-quality data were collected from row crop (corn and soybean), alfalfa, and pasture fields. In addition to the field settings, groundwater and soil data were collected from the existing farmyard and an abandoned feedlot. Groundwater samples were analyzed for pH, specific conductance, temperature, oxidation-reduction potential, metals, anions, nutrients, herbicides, and various isotopes. Soil samples were analyzed for pH, bioavailable phosphorus, potassium, calcium, magnesium, zinc, organic matter, total nitrogen, and inorganic nitrogen (nitrate-N). Soil- and …

Nutrient Concentrations At Baseflow Conditions In The Upper White River Basin, Southwest Missouri And Northwest Arkansas, Gopala G. Borchelt Jan 2007

Nutrient Concentrations At Baseflow Conditions In The Upper White River Basin, Southwest Missouri And Northwest Arkansas, Gopala G. Borchelt

MSU Graduate Theses

The Upper White River Basin (UWRB) is becoming increasingly vulnerable to water quality degradation from urban/population growth and increased agricultural production. This study examines the relationships among nutrient levels, water chemistry and watershed characteristics of 19 watersheds in the UWRB. Water samples were collected during baseflow conditions each month for one year at USGS continuous-flow gage stations. Watershed characteristics evaluated were land use, geology, drainage area, flow discharge, and wastewater treatment plant discharge (WTP). Measured chemical water quality indicators include total nitrogen (TN), total phosphorus (TP), specific conductivity, turbidity, pH and dissolved oxygen. Rapidly expanding urban areas are associated with …

Water-Quality And -Quantity Data For Abandoned Underground Coal Mines In Eastern Kentucky, Steven E. Webb, Dennis H. Cumbie, James S. Dinger, Leslie K. Russo Jan 2006

Water-Quality And -Quantity Data For Abandoned Underground Coal Mines In Eastern Kentucky, Steven E. Webb, Dennis H. Cumbie, James S. Dinger, Leslie K. Russo

Information Circular--KGS

Water-quality and -quantity analyses were performed between 1997 and 2003 by the Kentucky Geological Survey under contract from the Kentucky River Authority and the Kentucky Infrastructure Authority to study abandoned underground coal mines as possible water supplies for communities in the Eastern Kentucky Coal Field. The steep terrain of the coal field limits surface-water supplies, and groundwater systems are difficult to locate and often have too low a yield to provide community water supplies. KGS has been working with the Kentucky River Authority, the Kentucky Infrastructure Authority, and local government officials to search for water supplies in abandoned underground coal …


Soil Phosphorus Levels In Residential Lawns And Comparisons Among Four Land Uses In Springfield, Missouri, Timothy R. Davis Jan 2006

Soil Phosphorus Levels In Residential Lawns And Comparisons Among Four Land Uses In Springfield, Missouri, Timothy R. Davis

MSU Graduate Theses

Eutrophication of surface waters due to high phosphorus (P) concentrations is an important water quality concern in Greene County, Missouri. Phosphorus enrichment has been linked to a variety of non-point sources including runoff from both agricultural and urban land uses. Soil P has been shown to be a source of P in runoff. The differences in soil P among different land uses may provide insight into which land use contributes more P in runoff. This study examines the soil composition, geochemistry and total P concentration of surface soil (0-5cm) in four land uses in Greene County, Missouri. The land uses …


Nutrient Loads In An Urban Ozark Watershed: Jordan, Fassnight And Upper Wilson's Creeks, Springfield, Missouri, Ronald B. Miller Jan 2006

Nutrient Loads In An Urban Ozark Watershed: Jordan, Fassnight And Upper Wilson's Creeks, Springfield, Missouri, Ronald B. Miller

MSU Graduate Theses

The study watershed includes Jordan Creek, the primary stream draining the central downtown area of Springfield, Missouri, and also Fassnight and upper Wilson Creeks. Ten sample sites were established within the watershed and water samples and were collected during baseflow and storm runoff events between August 1, 2004 and July 31, 2005. Samples were tested for total nitrogen (TN), total phosphorus (TP) and selected heavy metals (zinc, arsenic, lead, copper and cadmium) and the parameters pH, specific conductance, turbidity, temperature and dissolved oxygen. Rating curves were used to correlate discharge and water quality variables. Separate rating curves were developed for …
