High-Resolution Water Footprints Of Production Of The United States

Daugherty Water for Food Global Institute: Faculty Publications

The United States is the largest producer of goods and services in the world. Rainfall, surface water supplies, and groundwater aquifers represent a fundamental input to economic production. Despite the importance of water resources to economic activity, we do not have consistent information on water use for specific locations and economic sectors. A national, spatially detailed database of water use by sector would provide insight into U.S. utilization and dependence on water resources for economic production. To this end, we calculate the water footprint of over 500 food, energy, mining, services, and manufacturing industries and goods produced in the United …

Hydrodynamic And Water Quality Modeling Of The Tigris River System In Iraq Using Ce-Qual-W2, Muhanned Al Murib

Dissertations and Theses

The Tigris River is one of two primary rivers in Iraq and is, along with the Euphrates, the main source for drinking and irrigation water in the country. The Tigris River originates in the Taurus Mountains in Turkey, and is 1850 km long. The majority of the river lies within Iraq. The river passes through, and is the primary drinking water source for major cities such as Mosul, Baeji, Samarra, Baghdad (the capital), and Kut. The Tigris River joins the Euphrates River in Qurna city within Basra province to form the Shatt Al-Arab River which eventually discharges into the Persian …

Organizing Under Austerity: How Residents’ Concerns Became The Flint Water Crisis, Amy Krings, Dana Kornberg, Erin Lane

Social Work: School of Social Work Faculty Publications and Other Works

What might it take for politically marginalized residents to challenge cuts in public spending that threaten to harm their health and wellbeing? Specifically, how did residents of Flint, Michigan contribute to the decision of an austerity regime, which was not accountable to them, to spend millions to switch to a safe water source? Relying on evidence from key interviews and newspaper accounts, we examine the influence and limitations of residents and grassroots groups during the 18-month period between April 2014 and October 2015 when the city drew its water from the Flint River. We find that citizen complaints alone were …

Precipitation Extremes In Dynamically Downscaled Climate Scenarios Over The Greater Horn Of Africa, Andualem Shiferaw, Tsegaye Tadesse, Clinton M. Rowe, Robert Oglesby

National Drought Mitigation Center: Faculty Publications

This study first assesses the performance of regional climate models in the Coordinated Regional Climate Downscaling Experiment (CORDEX) in reproducing observed extreme precipitation indices over the Greater Horn of Africa (GHA) region during 1989–2005. The study then assesses projected changes in these extremes during 2069–2098 compared to 1976–2005. The Regional Climate Model (RCM) simulations are made using two RCMs, with large-scale forcing from four CMIP5 Global limate Models(GCMs) under two Representative Concentration Pathways (RCP4.5 and RCP8.5). We found that RCM simulations have reasonably captured observed patterns of moderate precipitation extreme indices (MPEI). Pattern correlation coefficients between simulated and observed MPEI …

How Much Water Can We Save By Achieving Renewable Portfolio Standards In The Southwest United States?, Yuzhen Feng, Sachiko Sueki, Dale Devitt, Kumud Acharya

Life Sciences Faculty Research

Electricity in the Southwestern United States is primarily generated with water intensive steam turbines. If energy demand continues to rise this will lead to a further rise in water demand. A comprehensive understanding of water consumption and withdrawal for utility scale generation of electricity is necessary before any improvements in the water efficiency of such systems in arid environments can be made. This study estimated and compared the water usage associated with thermoelectric generation (i.e., natural gas, coal), and solar energy, in the five driest Colorado River Basin states: Utah, New Mexico, Nevada, Arizona, and California. This study also examined …

Extreme Precipitation Events, Impacts, Trends And Projections For Indiana, Sam Lashley

Purdue Road School

The National Weather Service is working with core partners to build a Weather Ready Nation for present and future generations by taking advanced action against the devastating impacts of extreme weather events, including extreme precipitation and flooding. One way in which this can be accomplished is by studying trends in historical weather data and applying what we learn to future mitigation efforts. The goal is to gain a better understanding of the magnitude and impacts that future extreme precipitation events may have on local infrastructure.

This presentation will review extreme rainfall and flooding events that have occurred across Indiana along …

Public Health Sciences Faculty Publications

In this study, we conducted a worst-case risk assessment for children’s health from ingestion exposure to water sources in two densely populated counties of the Piedmont province of New Jersey—Hunterdon and Mercer counties. Carcinogenic and non-carcinogenic health risk estimates for 19 contaminants, representing 3 different chemical classes—organic, inorganic and contaminants of emerging concern (CEC), for which environmental monitoring data are available—were generated. The three exposure scenarios examined were: (1) ingestion exposure to untreated groundwater from contaminated private wells; (2) recreational exposure through incidental ingestion of water from the Delaware River; and (3) ingestion exposure through fish consumption sourced from the …

Synchrony — An Emergent Property Of Recreational Fisheries, Mark A. Kaemingk, Christopher J. Chizinski, Keith Hurley, Kevin L. Pope

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

1. Recreational fisheries are traditionally managed at local scales, but more effective management could be achieved using a cross-scale approach. To do this, we must first understand how local processes scale up to influence landscape patterns between anglers and resources. We highlight how population-based synchrony methods, used in conjunction with a complex-adaptive-systems framework, can reveal emergent spatial properties within social-ecological systems such as recreational fisheries.

2. Herein, we quantified the level of spatial synchrony in angler behaviour, defined the relationship between angler synchrony and distance among waterbodies, and highlighted social-ecological attributes contributing to these patterns. We leveraged a 111 waterbody-year …

Removal Of Perfluorinated Compounds From Post-Emergency Wastewater By Advanced Oxidation Process And Granular Activated Carbon Adsorption, Sean M. Dyson

Theses and Dissertations

This research presents a novel approach to remove per- and polyfluoroalkyl substances (PFAS) from aqueous film-forming foam (AFFF) impacted wastewater with high (~100 mg/L) total organic carbon (TOC) concentrations. A treatment-train process was investigated involving an ultraviolet (UV)/hydrogen peroxide (H2O2) advanced oxidation process (AOP) followed by filtration using Calgon Filtrasorb® 600 (F600) granular activated carbon (GAC). UV/H₂O₂ AOP experiments were conducted to determine whether TOC concentrations could be reduced as a pre-treatment step before filtering the water with F600-GAC. Results showed using UV/H₂O₂ AOP reduced TOC in solution by > 98% (< 2 mg/L down from 99.1 mg/L). Reducing TOC concentrations was achieved by using a 250 mg/L H₂O_{2 …}

Application Of Ultraviolet Light Emitting Diodes For The Advanced Oxidation Of Guar Gum, Andrew W. Davenport

Theses and Dissertations

Guar Gum (GG) is one of the problematic water pollutants connected to hydraulic fracturing. There is a pressing need to investigate appropriate unit operations that can be employed to protect the aquatic environment. This study investigated the use of light-emitting diodes (LEDs) in the advanced oxidation process (AOP) of GG. Chemical oxygen demand (COD) removal provided mixed results, depending on the concentration of hydrogen peroxide (H₂O₂) in solution, and was between (0-95%) for H₂O₂-to-GG ratios between 7.0 and 176.3 g H₂O₂/g GG. COD removal was greatest at the …

Spartina patens is a dominant emergent macrophyte in fresh, intermediate, and brackish marshes along the Atlantic and Gulf coasts of United States where its biomechanical properties are a key component of wetland health and resilience. Its root biomass and tensile root strength are essential for anchorage, erosion protection, and are important determinants of soil strength. Nutrients and the herbicide atrazine are suspected of negatively impacting this wetland plant and others. The objectives of this study were to: 1) ascertain the tensile root strength of five emergent coastal macrophytes in coastal estuaries, and 2) test the effects of nutrient addition, atrazine …

Comparison Of The Performance Of Six Drought Indices In Characterizing Historical Drought For The Upper Blue Nile Basin, Ethiopia, Yared Bayissa, Shreedhar Maskey, Tsegaye Tadesse, Schalk Jan Van Andel, Semu Moges, Ann Van Griensven, Dimitri Solomatine

National Drought Mitigation Center: Faculty Publications

The Upper Blue Nile (UBN) basin is less-explored in terms of drought studies as compared to other parts of Ethiopia and lacks a basin-specific drought monitoring system. This study compares six drought indices: Standardized Precipitation Index (SPI), Standardized Precipitation Evaporation Index (SPEI), Evapotranspiration Deficit Index (ETDI), Soil Moisture Deficit Index (SMDI), Aggregate Drought Index (ADI), and Standardized Runoff-discharge Index (SRI), and evaluates their performance with respect to identifying historic drought events in the UBN basin. The indices were calculated using monthly time series of observed precipitation, average temperature, river discharge, and modeled evapotranspiration and soil moisture from 1970 to 2010. …

Expanding The "Active Layer", Peter Ashmore, Sarah Peirce, Pauline Leduc

Geography & Environment Publications

Church and Haschenburger (2017) make helpful distinctions around the issue of defining the active layer, with which we agree. We propose expanding discussion and definition of the ”active layer” in fluvial bedload transport to include the concept of the “morphological active layer”. This is particularly applicable to laterally unstable rivers (such as braided rivers) in which progressive morphological change over short time periods is the process by which much of the bedload transport occurs. The morphological active layer is also distinguished by variable lateral and longitudinal extent continuity over a range of flows and transport intensity. We suggest that the …

Bathymetry Data For Lakes Azuei And Enriquillo, Michael Piasecki, Mahrokh Moknatian

Publications and Research

This data set supports and forms the basis for the development of Digital Bathymetry Models (DBM) for Lakes Azuei (Haiti) and Enriquillo (Dominican Republic). Bathymetric Data is typically acquired using Sonar devices that measure the depth at specific points along a boat track and for which the longitude and latitude is recorded. From the resulting point cloud one develop a seamless representation of the floor of the lake on either a raster set (which is what we have done) or try to use a contour (vector representation) model in which the depth contours appear as polygons or -lines. The raw …

Factors Influencing Farmers’ Adoption Of Best Management Practices: A Review And Synthesis, Tingting Liu, Randall J. F. Bruins, Matthew T. Heberling

National Drought Mitigation Center: Faculty Publications

Best management practices (BMPs) for reducing agricultural non-point source pollution are widely available. However, agriculture remains a major global contributor to degradation of waters because farmers often do not adopt BMPs. To improve water quality, it is necessary to understand the factors that influence BMP adoption by farmers. We review the findings of BMP adoption studies from both developed and developing countries, published after (or otherwise not included in) two major literature reviews from 2007 and 2008. We summarize the study locations, scales, and BMPs studied; the analytical methods used; the factors evaluated; and the directionality of each factor’s influence …

Estimating Discharge In Low-Order Rivers With High-Resolution Aerial Imagery, Tyler V. King, Bethany T. Neilson, Mitchell T. Rasmussen

Publications

Remote sensing of river discharge promises to augment in situ gauging stations, but the majority of research in this field focuses on large rivers (>50 m wide). We present a method for estimating volumetric river discharge in low-order (wide) rivers from remotely sensed data by coupling high-resolution imagery with one-dimensional hydraulic modeling at so-called virtual gauging stations. These locations were identified as locations where the river contracted under low flows, exposing a substantial portion of the river bed. Topography of the exposed river bed was photogrammetrically extracted from high-resolution aerial imagery while the geometry of the remaining inundated portion …

National Drought Mitigation Center: Faculty Publications

Drought is one of the most serious climatic and natural disasters inflicting serious impacts on the socio-economy of Morocco, which is characterized both by low-average annual rainfall and high irregularity in the spatial distribution and timing of precipitation across the country. This work aims to develop a comprehensive and integrated method for drought monitoring based on remote sensing techniques. The main input parameters are derived monthly from satellite data at the national scale and are then combined to generate a composite drought index presenting different severity classes of drought. The input parameters are: Standardized Precipitation Index calculated from satellite-based precipitation …

Watershed Investigative Support To The Poteau Valley Improvement Authority: Stream Water Quality To Support Huc 12 Prioritization In The Lake Wister Watershed, Oklahoma, Bradley J. Austin, Brina A. Smith, Brian E. Haggard

Arkansas Water Resources Center Technical Reports

Nonpoint source pollution associated with human land use (agriculture and urbanization) is one of the leading causes of impairment to waterways in the United States (EPA, 2000). The primary pollutants associated with agricultural and urban land use are sediment and nutrients which enter nearby streams during rain events and are then carried downstream. These sediments and nutrients may result in water quality issues in the downstream water bodies like increased algal growth or decreased water clarity (e.g. Smith et al., 1999).

Civil and Environmental Engineering Faculty Publications and Presentations

This study presented the conceptual framework of the water-management analysis module (WMAM) to derive effective physical specifications for the design and planning of low-impact development (LID) practices using the storm-water management model (SWMM). This decision-support system can be used for six LID types and has the following key capabilities: determining relevant LID design parameters within the SWMM that critically influence the hydrological cycle components using a simple sensitivity analysis and determining the best hydrological values for LID planning specification. This study analyzed a highly urbanized university campus as a case study to determine the design and planning specifications for an …

Social Position Influencing The Water Perception Gap Between Local Leaders And Constituents In A Socio-Hydrological System, Melissa Haeffner, Douglas Jackson-Smith, Courtney G. Flint

Environmental Science and Management Faculty Publications and Presentations

How well city leaders represent their constituents and meet their needs are key concerns in transitioning to local sustainable water governance. To date, however, there is little research documenting the influence of social position between elected leaders who make policy, career staff water managers who design and operate systems and implement policies, and the members of the public whose individual water use behaviors are important drivers of water sustainability outcomes. In this study, we ask: ‘‘How does social position explain variation in water perceptions and concerns between different actors in a sociohydrological system?’’ Using a mixed method approach with survey …

Global Anthropogenic Phosphorus Loads To Freshwater And Associated Grey Water Footprints And Water Pollution Levels: A High-Resolution Global Study, Mesfin Mekonnen, Arjen Y. Hoekstra

Daugherty Water for Food Global Institute: Faculty Publications

We estimate the global anthropogenic phosphorus (P) loads to freshwater and the associated grey water footprints (GWFs) for the period 2002–2010, at a spatial resolution of 5 3 5 arc min, and com- pare the GWF per river basin to runoff to assess the P-related water pollution level (WPL). The global anthro- pogenic P load to freshwater systems from both diffuse and point sources is estimated at 1.5 Tg/yr. More than half of this total load was in Asia, followed by Europe (19%) and Latin America and the Caribbean (13%). The domestic sector contributed 54% to the total, agriculture 38%, …
