Basin focus:
San Pedro
Specific area in
basin /
field sites:
Upper San Pedro basin from the US-Mexico border
Summary/Goals: We are working with the Upper San Pedro Partnership to develop a dynamic simulation model for this region. The resulting decision support system (DSS) focuses on appropriate conservation measures to be instituted to move toward safe yield and predictions of groundwater conditions resulting from conservation and augmentation decisions.
Activities and outcomes during past year:
The principal modeling efforts during this period have been incorporating groundwater and riparian zone models within the DSS. We have developed response function based on the USGS groundwater model and embedded these within the model and DSS interface. We have also implement Stromberg's hydrologic/riparian zone health measure in the model. Numerous additional augmentation alternatives were also developed. Basic and Advanced models were largely completed. The basic interface was again revised for changes in the decision structure. The advanced model with detailed alternatives was modified to better clarify alternative purposes . An expanded suite of recharge locations has been included for distributing imported water in the subwatershed. This process entailed modifying the interface and adding new groundwater level response relationships.
A DSS workbook has been developed and is undergoing final review for distribution in early 2009. Several rollout meetings and demonstrations were conducted with the PAC and technical committees. The website address has been published and a link will be added to the USPP website. A journal paper was drafted on the modeling effort and a second manuscript was submitted for review on the development process. New result pages were prepared for USPP review on groundwater level changes away from the San Pedro river. Support was provided to the EPA "Bird" study by reverse engineering scenarios that caused a desired response to the river system.
Plans for the upcoming year:
Modifications to the website will continue to finalize the product. Changes are cosmetic and add new options and science to the model. Specifically, in terms of interfaces and outreach
1)The augmentation pages for the advanced model will be modified to be consistent with the present planning process.
2)Additional support pages will be developed including help and interpretation
3)The model will be translated to Spanish and made available on-line.
4)Rollout will continue with additional basic and advanced model training sessions.
5)The journal paper on the modeling portion of the project will be finalized and submitted to the Journal of the American Water Resources Association
With regards to modeling,
1)Climatic variability will be incorporated for mountain front recharge and riparian evapotranspiration by changing inflow/outflow rates and examining groundwater level impacts
2)Alternative growth patterns and higher detailed resolution will be added. The Alternative Futures plans will be used for growth patterns.
3)New sustainability indicators as developed the USPP will be incorporated as possible given timing and acceptance
4)Our team will continue interactions with the USGS and local entities to improve the overall water budget and insure consistency between USGS and DSS results
Organization Involvement:
The USPP is actively involved in defining project goals and desires for resulting model. This interaction is critical in developing a tool that will be used. We have met with the USPP's technical and political decision making groups.
Shared Resources / Joint Activities:
The USPP has provided all available data on the conservation measures and their water use and availability records.
