Daugherty Water for Food Global Institute: Faculty Publications

Integrated river basin management involves a sound knowledge of water and land interactions, and impacts from and feedbacks to human activity. Remote sensing has been an efficient and increasingly promising means of gathering direct information of the Earth surface, as well as information on water and energy fluxes. The recent generation of high-resolution sensors offers a huge potential for monitoring, assessing, and modelling our changing environment in a context of uncertainty about how future climate conditions will affect the current water resource and basin management framework. Moreover, large amounts of data are now available posing a challenging opportunity to the …

Riverbank Filtration Impacts On Post Disinfection Water Quality In Small Systems—A Case Study From Auburn And Nebraska City, Nebraska, Matteo D'Alessio, Bruce Dvorak, Chittaranjan Ray

Daugherty Water for Food Global Institute: Faculty Publications

Small water systems can experience a fluctuating quality of water in the distribution system after disinfection. As chlorine is the most common disinfectant for small systems, the occurrence of disinfection byproducts (DBPs) represents a common problem for these systems. Riverbank filtration (RBF) can be a valuable solution for small communities located on riverbanks. The objectives of this study were to evaluate (i) the improvements in water quality at two selected RBF systems, and (ii) the potential lower concentrations of DBPs, in particular, trihalomethanes (THMs), in small systems that use RBF. Two small communities in Nebraska, Auburn and Nebraska City, using …

Daugherty Water for Food Global Institute: Faculty Publications

The coastal waters of Hawaii are extremely important for recreation as well as for the health of the marine environment. Non-point source pollution from storm runoff poses a great threat to surface water quality in Hawaii. The State of Hawaii Department of Transportation (HDOT) includes infiltration trenches as a best management practice (BMP) option to reduce pollution caused by stormwater runoff. HDOT guidelines state that the implementation of BMPs is needed to reduce sediment and pollutant loads to streams and the ocean. In this study, the suitability of soils adjacent to highways on Oahu for the siting of infiltration trenches …

Energy Demand And Water Footprint Study Of An Agricultural Machinery Industry, Mantoam E,J., Mesfin Mekonnen, T.L. Romanelli

Daugherty Water for Food Global Institute: Faculty Publications

The intensification of agricultural production systems demands power, supplied by agricultural machinery, besides more agricultural inputs such as fertilizers, pesticides and seeds. Agricultural mechanization provides increase in the global production of food, fiber and bioenergy; and it brought economic benefits to producers, but causing larger energy consumption. Energy embodiment in agricultural machinery has been done in earlier studies, but data usually are from car industry. This study aimed to determine the energy demand and water footprint in a plant that assembles five types of agricultural machinery from a multinational manufacturer located in Piracicaba municipality in Sao Paulo state, Brazil. That …

Assessment Of Drinking Water/Aquifer Vulnerability To Contamination By Natural Manganese And Anthropogenic Chemicals In The U.S., Ryan Kelly

International Development, Community and Environment (IDCE)

Aquifers in the U.S. store groundwater used by many Americans every day for drinking eating, bathing and cleaning. These underground sources of water are vital to life and may be subject to contamination from both natural and anthropogenic pollution, including manganese (Mn) – especially shallow aquifers (<100 feet to bedrock). Natural sources of Mn are found in soils, surficial deposits, and bedrock, while anthropogenic contamination derives from landfills, waste facilities, or industries that use toxic materials. Pollutants like Mn raise concern because there is no policy in place to enforce regulation of Mn levels in water supplies based on limited information about health effects. Yet studies have shown elevated levels of Mn intake can lead to adverse human health effects. This study uses ArcMap to identify potential sources of Mn and/or toxics contamination in shallow U.S. aquifers based on geologic characteristics of a given aquifer source and proximity to waste sites. The results show approximately 2 million Americans may be at risk of consuming water with natural Mn contamination, and of those 2 million, close to 1.7 million are also vulnerable to additional toxics from anthropogenic waste. …

Evaluation Of The Weak Constraint Data Assimilation Approach For Estimating Turbulent Heat Fluxes At Six Sites, Xinlei He, Tongren Xu, Sayed M. Bateni, C.M.U. Neale, Thomas Auligne, Shaomin Liu, Kaicun Wang, Kebiao Mao, Yunjun Yao

Daugherty Water for Food Global Institute: Faculty Publications

A number of studies have estimated turbulent heat fluxes by assimilating sequences of land surface temperature (LST) observations into the strong constraint-variational data assimilation (SC-VDA) approaches. The SC-VDA approaches do not account for the structural model errors and uncertainties in the micrometeorological variables. In contrast to the SC-VDA approaches, the WC-VDA approach (the so-called weak constraint-VDA) accounts for the effects of structural and model errors by adding a model error term. In this study, the WC-VDA approach is tested at six study sites with different climatic and vegetative conditions. Its performance is also compared with that of SC-VDA at the …

High-Resolution Digital Surface Characterization Of The Rio Chama In New Mexico, Rowan L. Converse

Shared Knowledge Conference

Over the past eighty years, the Rio Chama, a major tributary of the Rio Grande in New Mexico, has been subject to significant disruption of historic hydrological flow regimes due to water use demands. In recent years, a multiagency management effort has been initiated to restore some measure of historic flow regimes in the 39.6 km congressionally designated Wild and Scenic stretch through the Rio Chama Canyon Wilderness. We collaborated with managers at the US Army Corps of Engineers to collect approximately 15,870 frames of 10cm resolution multispectral imagery of the 82 km stretch of the river between El Vado …

Groundwater Recharge Response To Reduced Irrigation Pumping In Western Nebraska, Justin Philip Gibson

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

Given current and continued investment in irrigation scheduling technologies, a need exists to better estimate the longevity and magnitude of water savings at watershed level to avoid the paradox of irrigation efficiency. This paradox occurs within a watershed as not all irrigation inefficiencies lead to the system losing water. For example, irrigation pumping rates in excess of crop water demand may lead to enhanced groundwater recharge or surface runoff that migrates to a stream. Thus, increases in efficiency may not lead to similar magnitudes of water savings. I hypothesize that water savings longevities are short given previous work demonstrating rapid …

The Waters Of Antarctica: Do They Belong To Some States, No States, Or All States?, Linda A. Malone

William & Mary Environmental Law and Policy Review

Major issues and complexities arise when one is looking at the international puzzle that is Antarctica. Despite being uninhabited year round and lacking substantial long-term international law rules for sovereignty, states still try to claim their sovereignty over various parts of Antarctica. The consortium of states under the Antarctica Treaty System (“ATS”) then further aggravates these complexities, especially when other states outside of the ATS have been arguing for different regimes and approaches to dealing with Antarctica and resource exploitation. Due to these major issues and a desperate need for a resolution in times of global climate change, this Article …

When The Well Runs Dry: Why Water-Rich States Need To Prepare For Climate Change And Protect Their Groundwater, Danielle Takacs

William & Mary Environmental Law and Policy Review

It may seem surprising to see such concern over groundwater usage in a state like Wisconsin. While known for its dairy and cheese production, Wisconsin is first in the nation for producing snap beans and cranberries. Agriculture contributes $88.3 billion annually to Wisconsin’s economy alone. In addition to bordering two of the Great Lakes, Lake Michigan and Lake Superior, Wisconsin boasts that it is home to about 15,000 lakes. And this does not include the numerous rivers and streams throughout the state. These facts alone may make Wisconsin seem an unlikely place for disputes over groundwater, as water seems to …

Spatial Analysis Of Borrow Pits Along The Platte River In South-Central Nebraska, Usa, In 1957 And 2016, Nicole M. Pauley, Mary J. Harner, Emma M. Brinley Buckley, Paul R. Burger, Keith Geluso

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

The Central Platte River Valley (CPRV) of Nebraska provides critical habitat for wildlife, while serving agricultural, indus­trial, and other human uses. Mining of sand and gravel from the floodplain of the Platte River has supported construction of roads and other uses, and this extraction has created many borrow-pit ponds, lakes, and other small bodies of standing water (hereafter borrow-pits), further transforming riparian and prairie habitats. The objective of this study was to compare the abundance, size, and distribution of borrow pits before construction of Interstate 80 (1957) and at present (2016) from Lexington to Chapman, Nebraska, a length of river …

A Comparison Of Vnir And Mir Spectroscopy For Predicting Various Soil Properties, Joshua R. Gates

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

Soil plays an important role in our daily lives, namely producing food, cleaning water and storing carbon. The ability to rapidly and cost-effectively quantify the various components of soils can help us understand and better manage this important resource. This study aims to compare the ability of visible near-infrared (VNIR) spectroscopy and mid-infrared (MIR) spectroscopy to quickly and accurately predict various important soil properties (electrical conductivity, soil pH, cation exchange capacity, exchangeable cations, phosphorus, carbon, beta-glucosidase enzyme activity and nitrogen). Prediction models were developed using partial least squares regression (PLSR) techniques. Three different calibration sampling methods were tested along with …

Boundary Spanners And Trust Development Between Stakeholders In Integrated Water Resource Management: A Mixed Methods Study, Jodi L. Delozier

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

Natural resource issues are inherently complex, even more so are those that involve the management of water. Because watersheds tend to cross multiple jurisdictional and geographical boundaries, a diverse set of stakeholders are needed to develop appropriate and sustainable management policy. This research sheds light on the importance of boundary spanners assisting in the development of trust between stakeholders in integrated water resource management (IWRM). Previous literature has explored the advantages to boundary spanning leadership in business practice, emergency management, university and community management as well as fish and wildlife management, but has failed to address the area of integrated …

Distribution And Habitat Association Of The Northern Long-Eared Bat, Zachary A. Warren

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

Because of white-nose syndrome, the northern long-eared bat (Myotis septentrionalis) is experiencing rapid population declines across the majority of its range. This decline has prompted increased regulatory protection and thus an increased need for effective habitat management strategies. Insight into the species habitat associations, however, is a prior necessity to ensure management practices are biologically relevant. Understanding these relationships requires a holistic approach that addresses the multiple ways in which the species is interacting with its environment. The objective of my thesis was to address these relationships following a multi-scale approach that assessed the factors associated with roost …

Including Farmer Irrigation Behavior In A Sociohydrological Modeling Framework With Application In North India, Jimmy O’Keeffe, Simon Moulds, Emma Bergin, Nick Brozovic, Ana Mijic, Wouter Buytaert

Daugherty Water for Food Global Institute: Faculty Publications

Understanding water user behavior and its potential outcomes is important for the development of suitable water resource management options. Computational models are commonly used to assist water resource management decision making; however, while natural processes are increasingly well modeled, the inclusion of human behavior has lagged behind. Improved representation of irrigation water user behavior within models can provide more accurate and relevant information for irrigation management in the agricultural sector. This paper outlines a model that conceptualizes and proceduralizes observed farmer irrigation practices, highlighting impacts and interactions between the environment and behavior. It is developed using a bottom-up approach, informed …

Multi-Scale Analysis Of Common-Pool Resources For Ecosystem Conservation In The Orinoco River Watershed, Luisa Galindo

Doctoral Dissertations

Adaptive management strategies are mechanisms that help governments to overcome problems derived from the sudden change of ecosystems processes and dynamics and to maintain the provision of ecosystem services to the population. These strategies rely on multi-scale networks of governing institutions that work together for the protection of the environment and cooperate for the solution of pressing issues. Sometimes, however, two issues imperil the persistence of local institutions within these networks, (1) their rights to govern their territory and to self-organize are not recognized, and (2) the nested and polycentric systems that operate through the multi-scale network are weak or …

Assessment Of The Ponderosa Woodlands In Nebraska's Wildcat Hills: Implications For Juniperus Encroachment And Management, Allie Victoria Schiltmeyer

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

Ponderosa pine (Pinus ponderosa) is a dominant tree species across western North America. Its eastern distribution includes three populations in western Nebraska. This study assesses the distribution, structure and age of ponderosa pine woodlands in one of those regions, the Wildcat Hills. The Wildcat Hills have escaped severe wildfires seen in recent decades in other ponderosa pine regions. Nevertheless, the Wildcat Hills woodlands face multiple threats including climate change, wildfire, drought, pine beetles, and invasive species. Key to these threats is the stand structure of pine woodlands, which have increased in density across much of ponderosa pine’s range. …
