Establishing Relationships Between Drought Indices And Wildfire Danger Outputs: A Test Case For The California-Nevada Drought Early Warning System, Daniel J. Mcevoy, Mike Hobbins, Timothy J. Brown, Kristin Vander Molen, Tamara Wall, Justin L. Huntington, Mark D. Svoboda

National Drought Mitigation Center: Faculty Publications

Relationships between drought indices and fire danger outputs are examined to (1) incorporate fire risk information into the National Integrated Drought Information System California–Nevada Drought EarlyWarning System and (2) provide a baseline analysis for application of drought indices into a fire risk management framework. We analyzed four drought indices that incorporate precipitation and evaporative demand (E0) and three fire indices that reflect fuel moisture and potential fire intensity. Seasonally averaged fire danger outputs were most strongly correlated to multi-scalar drought indices that use E0 (the Evaporative Demand Drought Index (EDDI) and the Standardized Precipitation Evapotranspiration Index (SPEI)) at approximately annual …

Life Without The Beach: Projected Sea Level Rise And Its Impact On Barrier Islands Along The East Coast, Usa, Cara Johnson, Gabrielle N. Kase, Samantha B. Pfeffer

Student Publications

As climate change is becoming a global issue, the impact of sea level rise is increasingly becoming a threat to humans, wildlife, infrastructure, and ecosystems. To evaluate the effects of sea level rise on barrier islands and coastal regions, we studied future projections of sea level rise at Ocean City and Assateague Island, Maryland. We hypothesize that the sea levels at Assateague and Ocean City will have different beach profiles, and will show different levels of flooding through the Representative Concentration Pathways (RCP) simulations. We measured beach profiles at four locations, two at Ocean City and two at Assateague Island, …

Precipitation Trends Across The Commonwealth Of Virginia (1947 – 2016), Michael J. Allen, Thomas R. Allen

Virginia Journal of Science

Water is an important resource for the Commonwealth of Virginia. Too much water increases runoff, disrupt transportation networks, and contributes to school closures. Too little water may adversely impact agricultural operations. To improve climate-related information to Virginia citizens, this study assesses means and changes in precipitation across the Commonwealth of Virginia (1947 – 2016). Using daily station-level precipitation data from the Global Historical Climate Network (GHCN), descriptive statistics were calculated for 43 locations in terms of total precipitation (inches decade^-1), precipitation days (x>0”), and heavy precipitation days (x>1.0”). On average, locations showed an overall increase in …

Save Money, Save Water; Developing A Risk Model For Leak Detection And Pipe Replacement Using Spatial Analysis, Angelique Desiree Maldonado

Water Resources Professional Project Reports

It is imperative to properly and proactively maintain a distribution pipe system. The benefits to optimizing a pipe distribution system include ensuring a safe water quality, reducing water loss from leaks and line breaks, minimizing revenue losses and providing a reliable service. There are also economic concerns as pipe replacement is extremely expensive; in the state of New Mexico, an estimated $1.16 billion in drinking water infrastructure is needed over the next 20 years. (USEPA 2013). Because distribution pipe is so costly to replace, an approach that only looks at age or type or non-system specific data may overestimate the …

Balancing Act: Water Quality Protection And Flood Resilience, Samatha Becker

Virginia Coastal Policy Center

Flood resilience efforts and laws designed to protect water quality may not always be compatible under current Virginia law. This paper will discuss two examples in particular. First, there can be tensions between the water quality goals under the Chesapeake Bay Preservation Act and efforts to conduct flood resilience projects within 100 feet of the shoreline in Tidewater Virginia. Second, there are significant challenges faced by localities seeking to comply with the Virginia Stormwater Management Program, while also continuing to mitigate the impacts of flooding. These two examples stem from the larger question facing Virginia: as flooding increases, how does …

This paper next looks at particularly relevant water supply solutions, including bringing the agriculture industry to the table, implementing aquifer storage and recovery and groundwater trading programs, embracing “One Water” plans, and expanding water budgeting laws in the state. Each section first examines the actions that Virginia has already undertaken, before highlighting examples of success in the west and making recommendations for ways in which Virginia …

Phase Ii Ms4 Permit Requirements: A Survey Of Public Education And Outreach & Public Involvement And Participation Efforts, Connor Jennings, Donnie Autry

Virginia Coastal Policy Center

Under the Clean Water Act (CWA), various types of stormwater discharges must be regulated through the National Pollutant Discharge Elimination System (NPDES) permitting program, since the water often flows untreated into local waterways and potentially could contain high levels of pollution and contaminants. Municipal Separate Storm Sewer Systems (MS4s) consist of any conveyance designed to collect or convey stormwater (e.g., storm drains, underground pipes, gutters, curbs) that are not part of a combined sewer system or water treatment plant. Generally, these systems are owned by municipalities but can also include large users such as public universities, hospitals, and military bases. …

Process-Based Modeling Of The Dairy Mckay Watershed To Inform Monitoring For Agricultural Best Management Practices, Brittany Saeman

Environmental Science and Management Professional Master's Project Reports

The project described in this paper specifically looks at the influence of land management practices on water quality, specifically total phosphorus (TP) loads in the Dairy McKay Watershed (DMW). The project is being used to inform a water quality monitoring plan for the Oregon DEQ via outputs from a SWAT model. The DMW is known to have high TP levels that are linked to low dissolved oxygen levels in the Tualatin River. There is a total maximum daily load (TMDL) for the Tualatin River that specifies target TP levels coming out of the DMW, if these targets are met, the …

Analysis Of Toxic Pollutant Sources And Characteristics Contributing To Water Quality Impairments In The Willamette River Basin, Melinda Borgens

Environmental Science and Management Professional Master's Project Reports

Point and nonpoint sources contribute toxic pollutants to surface waters, degrading water quality and impairing aquatic and human life. As of 2012, 51 stream segments totaling approximately 6,000 kilometers (3,750 miles) in Oregon’s Willamette River Basin (the Basin) were listed as impaired on the Clean Water Act's (CWA) Section 303(d) list with 48 toxic pollutants. These toxic pollutants exceed the Oregon Department of Environmental Quality's (DEQ) state water quality standards, requiring Total Maximum Daily Loads (TMDLs) to restore water quality and protect beneficial uses. Identifying toxic pollutant point and nonpoint sources, and the total loads a waterbody receives, are critical …

Mapping Valley Bottom Confinement At The Network Scale, Gary R. O'Brien, Joseph Michael Wheaton, Kirstie Fryirs, William W. Macfarlane, Gary Brierley, Kelly Whitehead, Jordan T. Gilbert, Carol Volk

Watershed Sciences Faculty Publications

In this article, we demonstrate the application of a continuous confinement metric across entire river networks. Confinement is a useful metric for characterizing and discriminating valley setting. At the reach scale, valley bottom confinement is measured and quantified as the ratio of the length of channel confined on either bank by a confining margin divided by the reach length. The valley bottom is occupied by the contemporary floodplain and/or its channel(s); confining margins can be any landform or feature that makes up the valley bottom margin, such as bedrock hillslopes, terraces, fans, or anthropogenic features such as stopbanks or constructed …

Executive Summary:

In early 2017, Jake Aman, representing the Wells National Estuary Research Reserve (WNERR), met with the Cape Elizabeth Public Works Director and Town Planner to talk about culverts. Jake shared aerial photos of culverts located in the Spurwink Marsh where scouring of adjacent habitat areas was evident. He inquired if the town was considering any culvert replacements, in which case WNERR and The Nature Conservancy might be able to partner with the town to promote a habitat sensitive replacement. The outcome of the meeting was a jointly sponsored assessment of major town culverts, including those located in the …

Virus Adsorption To Colloids In Water: Interactions Between Bacteriophage Ms2, Kaolinite, And Fiberglass, Ashlee N. Ellis

Theses and Dissertations

Virus adsorption to colloidal particles is an important issue in the water quality community, and it is a particularly important issue for conventional wastewater treatment plants that accept biohazardous waste. Colloids impact the transport of viruses in engineered treatment systems, and they also provide protection against oxidants and other destructive mechanisms. This study evaluated the adsorption of bacteriophage MS2 to colloidal suspensions of kaolinite (KAO) and fiberglass (FG). A series of laboratory batch tests were carried out over a range of experimental conditions to determine kinetic rate constants and characterize bond strength, and computational experiments were done to assess both …

Rivers serve as an important medium for the exchange of elements between land, ocean, and atmosphere. This thesis consists of three interconnected studies with the overarching goal of analyzing the environmental factors influencing dissolved carbon dynamics and river geochemistry in large rivers. These studies utilized river water samples and in-stream measurements collected from the Mississippi and Atchafalaya Rivers at hourly to monthly intervals between 2013 to 2018, along with ambient river and meteorological data downloaded from public-access databases. Results indicate substantially higher dissolved organic carbon concentrations (DOC, 611 ±181 µmol L^-1) but lower concentrations of dissolved inorganic carbon …

A Multi-Criteria Gis Model For Suitability Analysis Of Locations Of Decentralized Wastewater Treatment Units: Case Study In Sulaimania, Iraq, Ako Rashed Hama, Rafea Hashim Al-Suhili, Zeren Jamal Ghafour

Publications and Research

Sulaimania is a City located in Kurdistan region in the north of Iraq. The city is facing a lack of water, and it will reach a very critical condition shortly. One of the potential solutions is to reuse the treated wastewater for non-direct human uses such as irrigation, washing, firefighting, groundwater recharging, and others. There is no sewage treatment plant in the city. The wastewater flows into a stream through some sewer outlets, and that causes big environmental issues. Decentralized wastewater treatment units (DTUs) are suggested to solve the issue. The treated wastewater will be used for the irrigation of …

An Assessment Of The Influence Of Local Conditions On The Economic And Environmental Sustainability Of Drain Water Heat Recovery Systems, Anusha Ravichandran

USF Tampa Graduate Theses and Dissertations

Increasing resource demand and decreasing supplies necessitate a paradigm shift in wastewater management from treatment to resource recovery. As the economic and environmental performance of wastewater-based resource recovery systems is location-specific (e.g., terrain slope influences hydro-energy recovery), a holistic view of their sustainability requires a comprehensive analysis on the effect of the local conditions on these systems. Although the internal factors affecting such systems (e.g., water quality and end use) are well studied, there is limited literature on the effect of external factors such as topography, climate and population density. This study evaluated the role of climate and population density …

Using Watershed Pour-Point Elevations To Evaluate The Base Of Fresh Groundwater In The Cumberland Plateau Of Eastern Kentucky, Ethan S. L. Davis, Thomas M. Parris, Jerrad Grider

Report of Investigations--KGS

Horizontal drilling with hydraulic fracturing at shallow depths (less than 2,200 ft) in the Devonian Berea Sandstone oil and gas play, along with the potential for high-volume hydraulic fracturing in the nascent Cambrian Rogersville Shale gas play, have generated a renewed interest in protecting groundwater quality in eastern Kentucky. A critical component of protection is an accurate understanding of the distribution of fresh water in the subsurface. The “Fresh-Saline Water Interface Map of Kentucky” by H.T. Hopkins, published by the U.S. Geological Survey and Kentucky Geological Survey in 1966, has been a critical reference for assessing the maximum depth of …

Limits To The World’S Green Water Resources For Food, Feed, Fiber, Timber, And Bioenergy, Joep F. Schyns, Arjen Y. Hoekstra, Martijn J. Booij, Rick J. Hogeboom, Mesfin Mekonnen

Daugherty Water for Food Global Institute: Faculty Publications

Green water––rainfall over land that eventually flows back to the atmosphere as evapotranspiration––is the main source of water to produce food, feed, fiber, timber, and bioenergy. To understand how freshwater scarcity constrains production of these goods, we need to consider limits to the green water footprint (WFg), the green water flow allocated to human society. However, research traditionally focuses on scarcity of blue water––groundwater and surface water. Here we expand the debate on water scarcity by considering green water scarcity (WSg). At 5 × 5 arc-minute spatial resolution, we quantify WFg and the maximum sustainable level to this footprint (WFg,m), …

Examination Of The Climate Factors That Reduced Wheat Yield In Northwest India During The 2000s, Avik Mukherjee, Shih-Yu (Simon) Wang, Parichart Promchote

Plants, Soils, and Climate Faculty Publications

In India, a significant reduction of wheat yield would cause a widespread impact on food security for 1.35 billion people. The two highest wheat producing states, Punjab and Haryana in northern India, experienced a prolonged period of anomalously low wheat yield during 2002–2010. The extent of climate variability and change in influencing this prolonged reduction in wheat yield was examined. Daily air temperature (T_max and T_ave) was used to calculate the number of days above optimum temperature and growing degree days (GDD) anomaly. Two drought indices, the standard precipitation and evapotranspiration index and the radiation-based precipitation index, …

Building A High-Resolution Vegetation Outlook Model To Monitor Agricultural Drought For The Upper Blue Nile Basin, Ethiopia, Yared Bayissa, Tsegaye Tadesse, Getachew B. Demisse

National Drought Mitigation Center: Faculty Publications

To reduce the impacts of drought, developing an integrated drought monitoring tool and early warning system is crucial and more effective than the crisis management approach that is commonly used in developing countries like Ethiopia. The overarching goal of this study was to develop a higher-spatial-resolution vegetation outlook (VegOut-UBN) model that integrates multiple satellite, climatic, and biophysical input variables for the Upper Blue Nile (UBN) basin. VegOut-UBN uses current and historical observations in predicting the vegetation condition at multiple leading time steps of 1, 3, 6, and 9 dekades. VegOut-UBN was developed to predict the vegetation condition during the main …

Constituent Loads And Trends In The Upper Illinois River Watershed And Upper White River Basin: 2015 October Through 2018 September, Erin E. Scott, Brian E. Haggard

Nonpoint source (NPS) pollution is a concern in these watersheds, such as excess nutrients from agriculture and sediment from changes in land uses. Several NPS pollution projects have been funded by ANRC, including streambank restoration on Sager Creek and best management practices (BMP) to control urban sediment in Fayetteville. The purpose of this project was to collect water samples at 15 sites in the UWRB and …

Including Variability Across Climate Change Projections In Assessing Impacts On Water Resources In An Intensively Managed Landscape, Bangshuai Han, Shawn G. Benner, Alejandro N. Flores

Geosciences Faculty Publications and Presentations

In intensively managed watersheds, water scarcity is a product of interactions between complex biophysical processes and human activities. Understanding how intensively managed watersheds respond to climate change requires modeling these coupled processes. One challenge in assessing the response of these watersheds to climate change lies in adequately capturing the trends and variability of future climates. Here we combine a stochastic weather generator together with future projections of climate change to efficiently create a large ensemble of daily weather for three climate scenarios, reflecting recent past and two future climate scenarios. With a previously developed model that captures rainfall-runoff processes and …

Workshop participants identified “use cases” that list data gaps, needs, and uses for water data and answered questions on who needs data, what data do they need, in what form do they need the data, and what decisions need to be made about water in Texas. They described desires for future water data management …

Hunter And Angler Motivations, Preferences, And Barriers To Waterfowl Hunting In The Central United States, Matthew P. Hinrichs

School of Natural Resources: Dissertations, Theses, and Student Research

Since the mid-1980s, there has been a decrease in individuals participating in waterfowl hunting in the United States. The decline in participation has over-arching consequences for state and federal wildlife agencies in their ability to fund and manage habitat and waterfowl populations. There is a fundamental need to understand why individuals participate in waterfowl hunting and what barriers there are to participating in waterfowl hunting. An online survey was conducted in the summer and fall of 2018 asking waterfowl hunters, anglers, big game hunters, combination users (i.e., hunters that have multiple hunting and fishing permits), and small game hunters about …
