Arkansas Water Resources Center Technical Reports

The U.S. Environmental Protection Agency (USEPA) has been encouraging states to accerlate their efforts in developing numeric nutrient criteria to promulgate within respective water quality standards and regulations. Based on USEPA recommendations, many states are pursuing nutrient criteria development by assessing frequency distributions and stressor‐response relationships in historical databases, various special studies and the literature. The mini‐workshops described here were targeted toward state agency personnel and stakeholder groups with an interest in understanding statistical techniques that could be used to aide, guide and support numeric nutrient criteria. An initial workshop was conducted at the USEPA Regional Technical Assistance Group meeting …

Sestonic Chlorophyll-A And Nutrient Relationships Across The Red River Basin, Usa, Brian E. Haggard, J. Thad Scott, Scott D. Longing, John T. Metrailer

Arkansas Water Resources Center Technical Reports

The Red River is a trans‐boundary, multi‐jurisdictional basin, where water‐quality standards often change at the state lines. The state agencies with USEPA Region VI focused resources to organize water‐quality data from within this basin and have it statistically analyzed to evaluate the relationships between nutrients and sestonic chlorophyll‐a (chl‐a). There were 152 sites within the Red River Basin that had nutrient and sestonic chl‐a data, and these sites were narrowed down to 132 when a minimum number of observations was required. Sestonic chl‐a levels increased with increasing nutrient concentrations; these significant regressions were used to predict nutrient concentrations at 10 …

Alaska encompasses several climate types because of its vast size, high-latitude location, proximity to oceans, and complex topography. There is a great need to understand how climate varies regionally for climatic research and forecasting applications. Although climate-type zones have been established for Alaska on the basis of seasonal climatological mean behavior, there has been little attempt to construct climate divisions that identify regions with consistently homogeneous climatic variability. In this study, cluster analysis was applied to monthly-average temperature data from 1977 to 2010 at a robust set of weather stations to develop climate divisions for the state. Mean-adjusted Advanced Very …

Drought Monitoring: Historical And Current Perspectives, Michael J. Hayes, Mark D. Svoboda, Brian D. Wardlow, Martha C. Anderson, Felix Kogan

Drought is a normal, recurring feature of climate throughout the world, with characteristics and impacts that can vary from region to region. Figure 1.1 illustrates the regular occurrence of drought within the United States between 1895 and 2010 with approximately 14% of the country, on average (plotted by black dotted line), experiencing severe to extreme drought conditions during any given year. Drought conditions can persist in a region for several years, as occurred in the United States in the 1930s, 1950s, and early 2000s, and tree ring and other proxy records confirm that multiple-year droughts are part of the long-term …

Future Opportunities And Challenges In Remote Sensing Of Drought, Brian D. Wardlow, Martha C. Anderson, Justin Sheffield, Bradley D. Doorn, James P. Verdin, Xiwu Zhan, Matthew Rodell

National Drought Mitigation Center: Faculty Publications

The value of satellite remote sensing for drought monitoring was first realized more than two decades ago with the application of Normalized Difference Vegetation Index (NDVI) data from the Advanced Very High Resolution Radiometer (AVHRR) for assessing the effect of drought on vegetation, as summarized by Anyamba and Tucker (2012, Chapter 2). Other indices such as the Vegetation Health Index (VHI) (Kogan, 1995) were also developed during this time period and applied to AVHRR NDVI and brightness temperature data for routine global monitoring of drought conditions. These early efforts demonstrated the unique perspective that global imagers like AVHRR could provide …

Microwave Remote Sensing Of Soil Moisture Science And Applications, Son V. Nghiem, Brian D. Wardlow, David Allured, Mark Svoboda, Doug Lecomte, Matthew Rosencrans, Steven K. Chan, Gregory Neumann

National Drought Mitigation Center: Faculty Publications

Soil moisture is a fundamental link between global water and carbon cycles and has major applications in predicting natural hazards such as droughts and floods (National Research Council, 2007). From precipitation data, soil wetness can be estimated by hydrological land-surface models. In the United States, preliminary precipitation data are based on measurements gathered from many active stations nationwide each month, and it takes 3–4 months to assemble final, quality-controlled data. In the western United States, some climate divisions may have no stations reporting in a particular month or may lack first- or second-order stations, and significant blockages by mountains limit …

These two perspectives highlight the complexity of the development and use of triggers in drought risk management by drawing on the experience of the United States, which has the most sophisticated system of drought triggers in the world, and that of Australia that has the most developed and longest standing national drought policy based on principles of risk management. The paper explores the advantages and disadvantages of triggers in managing drought, …

Automatic Geomorphic Feature Extraction From Lidar In Flat And Engineered Landscapes, Paola Passalacqua, Patrick Belmont, Efi Foufoula-Georgiou

Watershed Sciences Faculty Publications

High-resolution topographic data derived from light detection and ranging (lidar) technology enables detailed geomorphic observations to be made on spatially extensive areas in a way that was previously not possible. Availability of this data provides new opportunities to study the spatial organization of landscapes and channel network features, increase the accuracy of environmental transport models, and inform decisions for targeting conservation practices. However, with the opportunity of increased resolution topographic data come formidable challenges in terms of automatic geomorphic feature extraction, analysis, and interpretation. Low-relief landscapes are particularly challenging because topographic gradients are low, and in many places both the …

The High Plains aquifer underlies about 112 million acres (about 175,000 square miles) in parts of eight States—Colorado, Kansas, Nebraska, New Mexico, Oklahoma, South Dakota, Texas, and Wyoming. Water levels declined in parts of the High Plains aquifer soon after the onset of substantial irrigation with groundwater (about 1950). This report presents the volume of saturated aquifer material and drainable water in storage in the High Plains aquifer in 2009; water-level changes in the High Plains aquifer from 1980 to 1995, 1995 to 2000, 2000 to 2005, and 2005 to 2009; and changes in the volume of drainable water in …

Hydrostratigraphic Interpretation Of Test-Hole And Surface Geophysical Data, Elkhorn And Loup River Basins, Nebraska, 2008 To 2011, Christopher M. Hobza, Paul A. Bedrosian, Benjamin R. Bloss

United States Geological Survey: Water Reports and Publications

The Elkhorn-Loup Model (ELM) was begun in 2006 to understand the effect of various groundwater-management scenarios on surface-water resources. During phase one of the ELM study, a lack of subsurface geological information was identified as a data gap. Test holes drilled to the base of the aquifer in the ELM study area are spaced as much as 25 miles apart, especially in areas of the western Sand Hills. Given the variable character of the hydrostratigraphic units that compose the High Plains aquifer system, substantial variation in aquifer thickness and characteristics can exist between test holes. To improve the hydrogeologic understanding …

A Brief History And Summary Of The Effects Of River Engineering And Dams On The Mississippi River System And Delta, Jason S. Alexander, Richard C. Wilson, W. Reed Green

United States Geological Survey: Water Reports and Publications

The United States Geological Survey Forecast Mekong project is providing technical assistance and information to aid management decisions and build science capacity of institutions in the Mekong River Basin. A component of this effort is to produce a synthesis of the effects of dams and other engineering structures on large-river hydrology, sediment transport, geomorphology, ecology, water quality, and deltaic systems. The Mississippi River Basin (MRB) of the United States was used as the backdrop and context for this synthesis because it is a continental scale river system with a total annual water discharge proportional to the Mekong River, has been …

The Feasibility Of Switchgrass For Biofuel Production, Rob Mitchell, Kenneth P. Vogel, Daniel R. Uden

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

Switchgrass research has been conducted cooperatively by the US Department of Agriculture and the University of Nebraska since the mid-1930s, with a primary focus on bioenergy since 1990 at several institutions. Progress has been made in switchgrass breeding and genetics, molecular genetics, establishment, fertility management, production economics, production energetics, harvest and storage management, ecosystem services and ethanol yield. A complete field-validated biomass production system has been developed for the Midwest and Central Plains. Even with favorable economic and sustainability results from field trials, switchgrass for bioenergy has not been adopted on a large scale. Lack of adoption is likely due …

Thermal-Based Evaporative Stress Index For Monitoring Surface Moisture Depletion, Martha C. Anderson, Christopher R. Hain, Brian D. Wardlow, Agustin Pimstein, John R. Mecikalski, William P. Kustas

National Drought Mitigation Center: Faculty Publications

The standard suite of indicators currently used in operational drought monitoring reflects anomalous conditions in several major components of the hydrologic budget—representing deficits in precipitation, soil moisture content, runoff, surface and groundwater storage, snowpack, and streamflow. In principle, it is useful to have a diversity of indices because drought can assume many forms (meteorological, agricultural, hydrological, and socioeconomic), over broad ranges in timescale (weeks to years), and with varied impacts of interest to different stakeholder groups. Farmers, for example, may be principally interested in soil moisture deficits, river forecasters will focus on streamflow fluctuations, and water managers will be concerned …

Information For Operation Of Water Supply Systems, L. Douglas James, Glen E. Stringham, J. Clair Batty

Reports

Introduction: Water requirements increase as more people use more water for domestic purposes. The increase is augmented as technological advances add to the water needs of agriculture and industry. Additional urban landscaping adds further to the demand. Simultaneously, the same forces increase demands for flood control, hydrelectric power, and navigation; and a more urbanized population want more flows preserved for productive natural environments, recreational use, and aesthetic enjoyment. The response over the years to these growing demands on water resources has been to supply increasing amounts of water and greater levels of development for other purposes by building more projects, …

Hydrologic Efficiency In Water Conservation, L. Douglas James

Reports

Introduction: The hydrologic cycle can be subdivided into three phases: 1)Humidity is transported within the atmosphere and becomes precipitation, and 2) Water moves downhill until eventually reaching the sea while all the time 3) Evapotranspiration returns exposed moisture to the atmosphere. During its movement, flowing water transports suspended sediments and dissolved minerals to reshape landforms and redistribute the mineral composition of the earth's surface throughout geologic time. It is during the second phase that flowing water can be diverted for uses that generally add to evaportranspiration (through consumptive use) and transport (through waste disposal). The water resources development that serves …

Cameras, Satellites, And Surveys: A Multi-Platform Approach To Monitoring Lake Conservation Behavior, Daniel D. Homeier

Honors Theses

Shoreline buffers are essential to maintaining lake water quality and there are numerous methods for their assessment. There is uncertainty in the benefits and drawbacks of different shoreline buffer assessment methods. In this study I explore three methods of remotely assessing shoreline buffers in the Belgrade Lakes Region of Maine: household surveys, geotagged shoreline photos, and satellite imagery. By comparing these three methods I will evaluate their accuracy and applicable scale when used to assess the presence and quality of shoreline buffers.

I used both parametric and non-parametric analysis to (1) evaluate the relative accuracy of 154 household surveys in …

Scale And Justice In Water Allocation, Marian J. Patrick

Theses: Doctorates and Masters

Water allocation is a fundamental part of water resources management. Water allocation is often a contested process because it involves multiple uses and users of water. Issues of justice arise when resources are, or are perceived to be, in short supply. When water is allocated the rules for the distribution of the resource may result in just outcomes for some stakeholders but may create injustices for other stakeholders. Issues of scale thus form an important component of water allocation. This thesis draws from an amalgam of ideas on justice, scale and water management and aims to present a conceptual framework …
