Influence Of Karst Landscape On Planetary Boundary Layer Atmosphere: A Weather Research And Forecasting (Wrf) Model–Based Investigation, Ronnie Leeper, Rezaul Mamood, Arturo I. Quintanar

High Plains Regional Climate Center: Staff Publications

Karst hydrology provides a unique set of surface and subsurface hydrological components that affect soil moisture variability. Over karst topography, surface moisture moves rapidly below ground via sink holes, vertical shafts, and sinking streams, reducing surface runoff and moisture infiltration into the soil. In addition, subsurface cave blockage or rapid snowmelt over karst can lead to surface flooding. Moreover, regions dominated by karst may exhibit either drier or wetter soils when compared to nonkarst landscape. However, because of the lack of both observational soil moisture datasets to initialize simulations and regional land surface models (LSMs) that include explicit karst hydrological …

The Tyronza River is located in northeast Arkansas and its watershed has a heavy agricultural presence that drastically affects habitat quality. Meanwhile, the Tyronza River hosts one of the more recent documented range extensions of the federally endangered fat pocketbook mussel [Potamilus capax (Green, 1832)]. The purpose of this study was to assess physical habitat, water quality, and biotic assemblages of the Tyronza River using the Arkansas Department of Environmental Quality’s (ADEQ) regional biometrics. Water samples were collected at 9 …

Factors That Contribute To Turbidity On The West Fork Of The White River In Arkansas, Chris Cotton, Brian Haggard

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

The West Fork of the White River (WFWR) exceeds the water quality standard for turbidity (10 NTU) set by the Arkansas Department of Environmental Quality and, since 1998, the river has been on Arkansas’s 303 (d) list of impaired water bodies unsuitable for aquatic life because of turbidity exceedances. To understand the factors that could be related to turbidity, total suspended solids (TSS), total inorganic suspended solids (TISS), total volatile suspended solids (TVSS), sestonic chlorophyll-a (Chl-a) concentrations, and turbidity were measured on three sample dates from nine sites on the WFWR. As the site location changed in the downstream direction, …

The Carbon Footprint Associated With Water Management Policy Options In The Las Vegas Valley, Nevada, Eleeja Shrestha, Sajjad Ahmad, Walter Johnson, Jacimaria R. Batista

Civil and Environmental Engineering and Construction Faculty Research

A system dynamics model was developed to estimate the carbon dioxide (CO₂) emissions associated with conveyance of water from the water source to the distribution laterals of the Las Vegas Valley. In addition, the impact of several water management policies, including water conservation, reuse, and population growth rate change was evaluated. The results show that, at present, nearly 0.53 million metric tons of CO₂ emissions per year are released due to energy use for water conveyance in distribution laterals of the Valley from Lake Mead, located 32.2 km (20 miles) southeast of the Las Vegas at an …

Quantifying Canal Leakage Rates Using A Mass-Balance Approach And Heat-Based Hydraulic Conductivity Estimates In Selected Irrigation Canals, Western Nebraska, 2007 Through 2009, Christopher M. Hobza, Michael J. Andersen

United States Geological Survey: Water Reports and Publications

The water supply in areas of the North Platte River Basin in the Nebraska Panhandle has been designated as fully appropriated or overappropriated by the Nebraska Department of Natural Resources (NDNR). Enacted legislation (Legislative Bill 962) requires the North Platte Natural Resources District (NPNRD) and the NDNR to develop an Integrated Management Plan (IMP) to balance groundwater and surface-water supply and demand in the NPNRD. A clear understanding of the groundwater and surface-water systems is critical for the development of a successful IMP. The primary source of groundwater recharge in parts of the NPNRD is from irrigation canal leakage. Because …

Removal Of Arsenic And Strontium From Aqueous Solution Using Ironoxide Coated Zeolitized Tuff, Nataliya V. Kasimtseva

UNLV Theses, Dissertations, Professional Papers, and Capstones

As world population grows so does the demand for safe drinking water. Meanwhile water resources become increasingly scarce and quality of natural water decreases due to a combination of natural and anthropogenic factors. Industry and agriculture have become a premiere source of hazardous constituents, along with natural processes such as rock weathering and volcanic eruptions. Our ability to remove hazardous constituents from water depends on chosen technology and nature of contaminant. Sorption and ion-exchange have been widely applied for water purification. Natural zeolites have been widely applied in water and waste water treatment as ion-exchangers for removal of harmful contaminants …

Simulation Of Groundwater Flow And Effects Of Groundwater Irrigation On Stream Base Flow In The Elkhorn And Loup River Basins, Nebraska, 1895-2055: Phase Two, Jennifer S. Stanton, Steven M. Peterson, Michael N. Fienen

United States Geological Survey: Water Reports and Publications

Regional groundwater-flow simulations for a 30,000-square-mile area of the High Plains aquifer, referred to collectively as the Elkhorn-Loup Model, were developed to predict the effects of groundwater irrigation on stream base flow in the Elkhorn and Loup River Basins, Nebraska. Simulations described the stream-aquifer system from predevelopment through 2005 [including predevelopment (pre-1895), early development (1895–1940), and historical development (1940 through 2005) conditions] and future hypothetical development conditions (2006 through 2033 or 2055). Predicted changes to stream base flow that resulted from simulated changes to groundwater irrigation will aid development of long-term strategies for management of hydrologically connected water supplies.

Water Quality Outreach And Education Strategies For Northwest Arkansas And Regional Watersheds, Katie Teague, John Pennington

Arkansas Water Resources Center Technical Reports

Stakeholders impact water quality and have a responsibility to protect, maintain, and improve water quality throughout northwest Arkansas and watersheds everywhere. But unless the roles of responsibility and stewardship among all stakeholders is communicated clearly and repetitively, there will be little progress made towards maintaining and improving water quality, while lawsuits, blame, and inaction will persist. Thus, the overall goal of water quality education and outreach is to improve the ability of stakeholders to take care of their watershed by teaching them what actions are or are not beneficial for water quality protection, maintenance, or improvements. Specific outreach and education …

Water Quality And Watershed Conditions In The Upper Illinois River Watershed, Brian Haggard, Andrew Sharpley, Leslie Massey
