Final SPDSS Memorandum <br />To: Ray Alvarado, Andy Moore, Ray Bennett, Brian Ahrens <br />From: Michael J. Smith, Gordon McCurry <br />Date: 2 August 2005 <br />Subject: Task 50.2 -Definition of Requirements for an Enhanced Data Centered <br />Modeling Process for the SPDSS Groundwater Component <br />Introduction <br />The objective of Task 50 of the SPDSS Groundwater Component is to evaluate current data <br />centered approaches that the State has implemented for groundwater modeling in other basins <br />and to design enhancements to this process for implementation in Phase 3. Task 50 is being <br />completed in three stages, with Technical Memoranda (TM) deliverables at each stage. The <br />initial stage (Task 50.1), summarized the existing data centered modeling process that has been <br />implemented by the State for the Rio Grande Decision Support System (RGDSS) and identified <br />candidate graphical user interface (GUI) tools for screening and selection in subsequent tasks. <br />The evaluation focused on groundwater processes, since surface water and consumptive use <br />related processes are mature and currently meet the State's needs. <br />The second stage (Task 50.2), addressed in this TM, defines and prioritizes potential <br />enhancements to the data centered modeling process. This includes identification of data types <br />used in the modeling, where the data reside, current processes to move data from the source <br />repository to the models and an identification and prioritization of enhancements. This second <br />stage also identifies needed output types for model development and future model use as well <br />as prioritizing development needs to provide these outputs. Recommendations for selection of <br />a primary GUI are provided, along with recommended tools and processes for implementation <br />in the SPDSS. The third stage (Task 50.3) will provide a scope of work for implementing high <br />priority enhancements during Phase 3. <br />The data centered approach to groundwater modeling defines processes and tools that facilitate <br />a linkage between data sources, such as HydroBase and State GIS coverages, and a numerical <br />groundwater model. This approach facilitates rapid updating of numerical models when <br />changes to underlying data sets occur, model simulation periods change, or additional <br />processes need to be incorporated. This capability requires use of model support tools that <br />allow definition of conceptual model elements independent of the numerical model. The <br />overall objectives of Task 50 are to design a data centered groundwater modeling process that <br />incorporates the best processes and modeling tools that were developed by the State for the <br />RGDSS modeling effort, and identify areas for enhancement for the SPDSS groundwater <br />modeling efforts. <br />
