Evaluation Of Evaporative Drivers And Hydrologic Influences Using Energy And Water Budget Techniques At A Shallow Saline Lake In The Western Sandhills Of Nebraska, Usa, Colin Peake
School of Natural Resources: Dissertations, Theses, and Student Research
The western Sandhills of Nebraska contain many shallow lakes and wetlands that interact strongly with groundwater and the overlying atmosphere. The region is semi-arid, and most of the lakes are saline, supporting a wide range of ecosystems. Water levels and salt concentrations are highly sensitive to variations in precipitation, evaporation, and groundwater fluxes, making the Sandhills an excellent laboratory for examining the effects of climate on the water balance of interdunal lakes. In this study, we investigate the atmospheric controls on evaporation rates, as well as the water balance of Alkali Lake, one of the more saline lakes in the …
A Comparative Study Of Underwater Robot Path Planning Algorithms For Adaptive Sampling In A Network Of Sensors, Sreeja Banerjee
A Comparative Study Of Underwater Robot Path Planning Algorithms For Adaptive Sampling In A Network Of Sensors, Sreeja Banerjee
Department of Computer Science and Engineering: Dissertations, Theses, and Student Research
Monitoring lakes, rivers, and oceans is critical to improving our understanding of complex large-scale ecosystems. We introduce a method of underwater monitoring using semi-mobile underwater sensor networks and mobile underwater robots in this thesis. The underwater robots can move freely in all dimension while the sensor nodes are anchored to the bottom of the water column and can move only up and down along the depth of the water column. We develop three different algorithms to optimize the path of the underwater robot and the positions of the sensors to improve the overall quality of sensing of an area of …

Using Temporal Changes In Drought Indices To Generate Probabilistic Drought Intensification Forecasts, Jason A. Otkin, Martha C. Anderson, Christopher Hain, Mark Svoboda
Using Temporal Changes In Drought Indices To Generate Probabilistic Drought Intensification Forecasts, Jason A. Otkin, Martha C. Anderson, Christopher Hain, Mark Svoboda
Drought Mitigation Center: Faculty Publications
In this study, the potential utility of using rapid temporal changes in drought indices to provide early warning of an elevated risk for drought development over subseasonal time scales is assessed. Standardized change anomalies were computed each week during the 2000–13 growing seasons for drought indices depicting anomalies in evapotranspiration, precipitation, and soil moisture. A rapid change index (RCI) that encapsulates the accumulated magnitude of rapid changes in the weekly anomalies was computed each week for each drought index, and then a simple statistical method was used to convert the RCI values into drought intensification probabilities depicting the likelihood that …

A Combined Chemical And Biological Approach To Transforming And Mineralizing Pahs In Runoff Water, Chainarong Sakulthaew, Steve D. Comfort, Chanat Chokejaroenrat, Clifford Harris, Xu Li
School of Natural Resources: Faculty Publications
The water quality of lakes, rivers and streams associated with metropolitan areas is declining from increased inputs of urban runoff that contain polycyclic aromatic hydrocarbons (PAHs). Our objective was to transform and mineralize PAHs in runoff using a combined chemical and biological approach. Using 14C-labeled phenanthrene, 14C-benzo(a)pyrene and a mixture of 16 PAHs, we found that ozone transformed all PAHs in a H2O matrix within minutes but complete mineralization to CO2 took several weeks. When urban runoff water (7.6 mg C L−1) replaced H2O as the background matrix, some delays in degradation rates …

Water-Use Restriction Information: Information Sharing Between Public Water Systems And State Government Offices, Christopher Carparelli
Water-Use Restriction Information: Information Sharing Between Public Water Systems And State Government Offices, Christopher Carparelli
Drought Mitigation Center: Faculty Publications
In many states there is an absence of communication between the state and local levels about many aspects of water resource management. This research examines the interaction between the state and local levels regarding water-use restrictions for public water systems (PWSs). This information is useful for state-level drought planning and mitigation through the assessment of drought impacts on public water supplies. Officials from five state-level entities that collect and disseminate local water-use restriction information were interviewed over the phone for this research. Each official was asked eleven questions about how and why their state collects and disseminates PWS water-use restriction …
Variable Bounds Analysis Of A Climate Model Using Software Verification Techniques, Peter Revesz, Robert Woodward
Variable Bounds Analysis Of A Climate Model Using Software Verification Techniques, Peter Revesz, Robert Woodward
CSE Conference and Workshop Papers
Software verification techniques often use some approximation method that identifies the limits of the possible range of values that variables in a computer program can take during execution. Current climate models are complex computer programs that are typically iterated time-step by time-step to predict the next value of the climate-related variables. Because these iterative methods are necessarily computed only for a fixed number of iterations, they are unable to answer many long-range questions that may be posed regarding climate change, for example, whether there are natural fluctuations or whether a tipping point is reached after which there is no return …

Determining The Dynamics Of Agricultural Water Use: Cases From Asia And Africa, Lisa-Maria Rebelo, Robyn Johnston, Poolad Karimi, Peter G. Mccornick
Daugherty Water for Food Global Institute: Faculty Publications
Across Africa and Asia, water resources are being affected by a complex mixture of social, economic, and environmental factors. These include climate change and population growth, food prices, oil prices, financial disruptions, and political fluctuations. The need to produce more food will have one of the largest impacts on water and will continue to reshape the patterns of agricultural water use in major food-growing regions. With this increasing demand on water for agriculture, from large-scale irrigation to intensification of rainfed systems, it is becoming increasingly important to ensure that water resources decision-making has access to information that captures the spectrum …

Examples Of Non-Noetherian Domains Inside Power Series Rings, William Heinzer, Christel Rotthaus, Sylvia Wiegand
Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications
Given a power series ring R∗ over a Noetherian integral domain R and an intermediate field L between R and the total quotient ring of R∗, the integral domain A = L ∩ R∗ often (but not always) inherits nice properties from R∗ such as the Noetherian property. For certain fields L it is possible to approximate A using a localization B of a particular nested union of polynomial rings over R associated to A; if B is Noetherian, then B = A. If B is not Noetherian, we can sometimes identify the prime ideals of B that are not …
