Assessing the energy consumption efficiency, irrigation application uniformity and life cycle assessment of groundwater-based irrigation systems in Oklahoma
Handa, Divya (2018-12)Irrigation systems across Oklahoma were tested from 2015 to 2018 with the aim of determining their energy consumption efficiencies, irrigation uniformities, and application efficiencies. The actual Overall Pumping Efficiency ... -
Assessment and Development of Remotely Sensed Evapotranspiration Modeling Approaches
Khand, Kul Bikram (2019-05-01)Remote sensing has been a promising approach to extracting distributed evapotranspiration (ET) information at varying spatial and temporal scales. Performances of several vegetation index (VI) based and remotely sensed ... -
Characterizing station aridity and improving the estimates of reference evapotranspiration in the Oklahoma Mesonet
Singh, Aseem Pal (2022-07)There is a consensus among the scientific community regarding the rise in air temperatures and changing precipitation patterns across the globe. Many areas around the world are expected to see increased aridity levels in ... -
Development of Digital Groundwater Models and Simulation of Groundwater Flow of the Rush Springs Aquifer in West Central Oklahoma
Ketchum, Qualla Jo (2015-12-01)Groundwater modeling has been used since the 1970�s as a way to analyze complex groundwater systems and to provide scientific evidence for management and policy determinations. The fundamental objective of this research ... -
Economics of Irrigated Crop Choices Using Center Pivot System in Oklahoma Panhandle
Ramaswamy, Karthik (2016-12-01)The study seeks to maximize the net benefits through extraction of groundwater from Ogallala aquifer in the Oklahoma Panhandle. In recent decades in most parts of the southern Great Plains overlying Ogallala, the water ... -
Evaluating capabilities of novel warm-season crops to fill forage deficit periods in the Southern Great Plains
Baath, Gurjinder Singh (2019-12)Low nutritive value of perennial grasses during mid-late summer limits stocker cattle production in the Southern Great Plains (SGP). Our objectives were to explore annual crop species that might fit as a summer forage, and ... -
Evaluating the Impacts of Variable Irrigation Management Strategies on the Performance of Cotton and Grain Sorghum Using Monitoring and Modeling Techniques
Masasi, Blessing (2019-05-01)Diminishing water resources have threatened irrigated agriculture in many semi-arid and arid regions across the globe. In these regions, both surface and groundwater resources have declined due to persistent droughts and ... -
Evaluating the least cost selection of agricultural management practices in the Five-Mile Creek area of Fort Cobb watershed
Rasoulzadeh Gharibdousti, Solmaz (2018-05)One of the main causes of water quality impairment in the United States is human induced Non-Point Source (NPS) pollution through intensive agriculture. The Fort Cobb Reservoir (FCR) watershed located in southwestern ... -
Evaluating the performance of irrigation scheduling approaches based on monitoring and modeling soil water status
Mehata, Mukesh (2022-07)Improving irrigation management through adopting scientific irrigation scheduling offers a great potential for optimizing irrigation applications and reducing water withdrawals. However, adoption of scientific irrigation ... -
Evaluation of established low impact development techniques: Assessing aged bioretention cells and clogging pervious concrete
McLemore, Alex James (2017-12)Low impact development practices are commonly installed to mitigate the negative impacts urbanization can have on stormwater runoff and the environment. Research on the long-term performance of aged low impact development ... -
Improving the drought risk assessment and preparedness for winter wheat farming in Oklahoma
Ajaz, Ali (2022-07)Droughts pose a persistent threat to agriculture in the Southern Great Plains (SGP). Oklahoma is a major contributor to dryland winter wheat farming in the SGP, acrop that is highly susceptible to drought episodes. Modern ... -
Measurement and modeling of soil moisture for irrigation management
Datta, Sumon (2020-05)Increasing strain on freshwater resources due to population growths, climate change, and excessive depletion of water resources necessitates research in maximizing beneficial water use in agriculture regions. Smart ... -
Modeling the pecan nut growth and carbohydrate requirement and application of models
Panta, Srijana (2021-12)The pecan nut is an important nut fruit in the USA economy, contributing more than $3.5 billion to the country's economy. The optimal time of different orchard activities like irrigation management, pesticide spray, and ... -
Monitoring and modeling soil salinity dynamics at greenhouse and field scales
Chamaki, Sheyda (2018-12)An integrated monitoring and modeling approach was undertaken in greenhouse and field scale in terms of three main studies. In the first study, the changes in soil salinity and several other chemical properties were ... -
Net ecosystem exchange of carbon dioxide and water vapor fluxes in winter wheat and canola under conventional till and no-till systems
Manjunatha, Priyanka (2019-05)It is crucial to understand the impacts of climatic and crop factors, and management practices on carbon and water dynamics of Wheat (Triticum aestivum L.) and Canola (Brassica napus L.) ecosystems for long-term water ... -
Response of corn yield to irrigation and nitrogen and the relationship between yield and NDVI measured by aerial imagery
Singleton, Kelsey (2022-05)Nitrogen (N) and water are among the key components that effect crop growth and yield outcome in the southern Great Plains. However, the effect of N and irrigation interaction on corn yields have not been studied in the ...
