Interactions Of Zooplankton And Phytoplankton With Cyanobacteria, Rebecca Alexander
Interactions Of Zooplankton And Phytoplankton With Cyanobacteria, Rebecca Alexander
School of Natural Resources: Dissertations, Theses, and Student Research
Cyanobacteria are a major concern in Nebraska reservoirs and are capable of producing toxins that can cause skin irritations and gastrointestinal problems, as well as affect the nervous system. It is important to determine the mechanisms that can cause cyanobacteria blooms due to the effect they can have on human health. The interaction of zooplankton and other phytoplankton groups with cyanobacteria is important because there is a biological component in surface waters that should be taken into consideration along with the physical and chemical parameters that have been noted to promote cyanobacteria. For example, zooplankton have the ability to alter …

As the climate in the midwestern United States becomes increasingly variable because of global climate change, it is critical to provide tools to the agricultural community to ensure adaptability and profitability of agricultural cropping systems. When used by farmers and their advisors, agricultural decision support tools can reduce uncertainty and risks in the planning, operation, and management decisions of the farm enterprise. Agricultural advisors have historically played a key role in providing information and guidance in these decisions. However, little is known about what these advisors know or think about weather and climate information and their willingness to incorporate this …

Impacts Of Climate Change On The Surface Water Balance Of The Central United States, 1984-2007, Bo Dong
Impacts Of Climate Change On The Surface Water Balance Of The Central United States, 1984-2007, Bo Dong
School of Natural Resources: Dissertations, Theses, and Student Research
The climate system and the hydrologic cycle are strongly connected with each other. Understanding the interactions between these two systems is important, since variations in climate can trigger extensive changes in the hydrologic cycle, with significant impacts on agriculture, ecosystems, and society. Observations over the central U.S. in recent decades show numerous changes in climatic variables. This includes decreases in cloud cover and wind speed, increases in air temperature, and seasonal shifts in precipitation rate and rain/snow fraction. To assess the impacts of these variations in climate on the regional water cycle, a terrestrial ecosystem/land surface hydrologic model (Agro-IBIS) is …

Documenting Change At Upper Hamburg Bend: Nebraska's First Side-Channel Restoration, Brandon L. Eder, Gerald Mestl
Documenting Change At Upper Hamburg Bend: Nebraska's First Side-Channel Restoration, Brandon L. Eder, Gerald Mestl
Great Plains Research: A Journal of Natural and Social Sciences
In 1996 a side channel was excavated on 629 hectares of former agricultural land at Upper Hamburg Bend on the Missouri River in Otoe County, NE. This was the first side channel constructed on the Missouri River in an attempt to restore lost aquatic habitat. The initial design was for an approximately 4,200 m long side channel to be constructed with a 3 m bottom width. Development ofthe site was to be dependent on flows diverted from the main channel of the river with a final projected top width of 61 m. The side channel was completed in the spring, …

Analytical Modeling Of Irrigation And Land Use Effects On Streamflow In Semi-Arid Conditions: Frenchman Creek, Nebraska, Jonathan P. Traylor
Analytical Modeling Of Irrigation And Land Use Effects On Streamflow In Semi-Arid Conditions: Frenchman Creek, Nebraska, Jonathan P. Traylor
Department of Earth and Atmospheric Sciences: Dissertations, Theses, and Student Research
With proliferation of various numerical models, water budget studies commonly resort to numerical modeling techniques. However, availability and uncertainty in input data limit advantages of this approach. Often, analytical models capture the major traits of the watersheds and can assimilate important data. We developed a model for baseflow-dominated watersheds and apply it to Frenchman Creek in southwestern Nebraska. Frenchman Creek has experienced large streamflow reductions since the 1950s. The cause of these reductions is a combination of irrigation, conservation terrace construction, and other land use changes. However, the influence of each factor has not been well quantified. The objective of …
