Summary/Goals: The goal of this project is to create a holistic set of coupled models that will allow for more accurate predictions of water usage within the San Pedro Basin. This will enable consultants and water managers to better manage water resources in a semi-arid environment.
Activities and outcomes during past year:
Professors Leticia and Carlos Rodriguez, of the National University of the Coast - UNL, Santa Fe, Argentina spent a sabbatical with SAHRS to attack this goal from approximately Feb. 2006 to Jan. 2007. A methodology to accomplish SW and GW coupling was developed and tested for a case where an analytic solution could be derived with good agreement. The methodology was then tested in a well instrumented reach of the San Pedro Basin with success for moderately varying surface flows. Convergence of the GW model did not occur for rapidly varying surface flows. This issue is now being addressed.
Plans for the upcoming year:
Prof. Carlos and Leticia Rodriquez will continue work on the project after returning to Argentina with the near term goal of correcting the convergence problem and producing a journal manuscript. A student of Tom Meixner has been identified to continue the work initiated.
