Decision Support Model for Optimal Water Pricing Protocol for Oklahoma Water Planning: Lake Tenkiller Case Study

Principal Investigators and Department:
Dr. Tracy Boyer, Agricultural Economics, Oklahoma State University
Dr. Art Stoecker, Agricultural Economics, Oklahoma State University
Dr. Larry Sanders, Agricultural Economics, Oklahoma State University

Project Abstract/Summary:
The objective of this study is to develop a water-pricing model that can be used in various locations in Oklahoma in support of the state water planning process. The researchers will develop methods to estimate both monetary and opportunity costs of surface water in the Illinois River and Lake Tenkiller under conditions of competing water uses and variable water supplies that could be later modified to include related groundwater supplies. The optimal water pricing protocol will internalize monetary and opportunity costs of water storage, treatment, and delivery systems; and encourage a sustainable supply of water over 50 years through water conservation, without discouraging economic growth.

 

Determination of Fracture Density in the Arbuckle-Simpson Aquifer from Ground Penetrating Radar (GPR) and Resistivity Data

Principal Investigators and Department:
Dr. Ibraham Cemen, Boone Pickens School of Geology, Oklahoma State University
Dr. Todd Halihan, Boone Pickens School of Geology, Oklahoma State University
Dr. Roger Young, Geology and Geophysics, University of Oklahoma

Project Abstract/Summary:
The ground water resources of Oklahoma are vital to the economic well being of the state. Modeling of ground water flow and yield requires an understanding of effect of the fractures in aquifer rocks. In the Arbuckle-Simpson aquifer, the carbonate substrate is highly fractured. The scope of this project is three-fold: (1) identifying fracture patterns and major faults in outcrops using high resolution 3-D GPR, (2) the acquisition of resistivity data corresponding to the GPR data and its interpretation, and (3) repeat surveys for both GPR and resistivity data acquisition under wet rock conditions. A comparison of the data acquired in dry and wet conditions may help determine whether the fractures are open or closed. The results of this research could be beneficial to the Arbuckle-Simpson Aquifer ground water modeling work currently underway at both the Oklahoma Water Resources Board and the United States Geological Survey.

 

Subsurface Transport of Phosphorus to Streams: A Potential Source of Phosphorus not Alleviated by Best Management Practices

Principal Investigators and Department:
Dr. Garey Fox, Biosystems and Ag Engineering, Oklahoma State University
Dr. Chad Penn, Plant and Soil Sciences, Oklahoma State University
Dr. Dan Storm, Biosystems and Ag Engineering, Oklahoma State University

Project Abstract/Summary:
This research will determine the importance of subsurface transport of phosphorus to streams and rivers in Eastern Oklahoma. At a selected site in the Eucha/Spavinaw Basin, researchers will install trench 7 to 15 m away and parallel to the creek. Sampling sites will be installed every 1 to 2 m between the trench and river for monitoring flow and water quality. Creek water will then be pumped into the trench to maintain a constant head. Two different experiments will then be performed by spiking water in the trench with: (1) a conservative tracer and (2) a higher P concentration. Soil samples will also be analyzed for appropriate soil and hydraulic properties. Information from this research will be critical for watershed scale analyses of P loading to streams as current watershed models do not account for this transport mechanism. Data obtained from this experiment will be directly incorporated into these models. Results will provide information on the ability of subsurface soils to remove P from P rich subsurface flow. Also, the validity of installing riparian buffers or other best management practices on these porous soils will be assessed.
