Research, along with monitoring and modeling, are the three legs of the scientific stool that support ecosystem restoration and management. Monitoring tells us what is happening, research tells us why and how it is happening, and modeling provides insights about what can happen under different management alternatives.”

Various USPP members conduct research that informs how the water needs in the Sierra Vista Subwatershed of the Upper San Pedro Basin will be met. This research includes analyses and assessments of various elements of the water cycle that influence the availability groundwater and surface water supplies. This research and resulting results or findings are available:

  • To support decisions that help balance water availability for the area’s residents, property owners and the San Pedro Riparian National Conservation Area (SPRNCA).
  • To support members’ projects, policy decisions and public outreach.
  • To be reported out at the annual science summit.
  • To be integrated with other related research and provide input to other partners on key technical issues.                                                                                                                                       

The need for research on a specific topic may be requested by members at Partnership Advisory Committee (PAC) meetings and/or by the Science and/or Technical Advisor representatives from those members directly at the Technical Committee meetings. Recommendations for research funding is brought by the other committees or members to the Administrative Committee.

Featured Presentations

The following presentation materials have been presented at Upper San Pedro Partnership meetings by presenters or their company or agency for the benefit of the USPP members and to meet Partnership information needs. Presentation materials and all data, information or software referenced therein is shared at the discretion of the presenters. The USPP is providing interested parties access to this information for the purpose of informing water conservation (and management) in the Sierra Vista Subwatershed. Some data may be preliminary and subject to change. If you desire to cite this work, please contact the author.

Making the best decisions requires the best information. Research studies help refine the understanding of the problem and identify conservation actions that will have the greatest impact. These studies include:

  • Groundwater Modeling – to describe how the groundwater system is related to the river and what the effects of water uses are on the entire system.
  • Water Augmentation Studies – to determine the feasibility and cost/yield benefit for using new sources of water.
  • Reuse and Recharge Studies – to investigate the feasibility of using urban enhanced runoff and/or treated effluent from surrounding communities like Sierra Vista, Bisbee, Huachuca City and Naco for recharge.
  • San Pedro Riparian NCA water needs study – to find out how much water the trees and other vegetation near the river actually use and will continue to need to stay healthy.
