149.3 An updated CDSS web site containing an ArcIMS implementation to display the latest <br />real-time streamflow data throughout the state. <br />149.4 An updated CDSS web site (from Task 149.1) with enhancements to allow display of <br />historical diversion and streamflow data. <br />Task 152 -Data Flow and Procedure Manual Documentation and Updated Baseline Data <br />Objective: <br />Document the flow of data from HydroBase through various administrative and modeling tools <br />within the CDSS, in order to facilitate understanding of the system, and develop improved <br />procedures applied to baseline data sets. <br />Background: <br />A number of documents currently exist that describe the HydroBase database (Data Dictionary) <br />and modeling processes (StateMod, StateCU, and MODFLOW documentation). A procedure <br />manual for StateMod has also been developed to describe the model file creation process. <br />However, a number of significant changes to the database and modeling environment have <br />occurred and the existing documents do not fully address the data flow between different models <br />used in CDSS (the documentation for each model focuses on the features of the specific model, <br />not integrated use). Additionally, the groundwater modeling procedures implemented for the <br />RGDSS are not referenced in the existing StateMod procedure manual. <br />Approach: <br />152.1 Review Existing Data Flow and Modeling Information. Review existing CDSS <br />documentation, in particular the StateMod and StateCU documentation, and create an <br />updated document to describe the data flow between HydroBase, CWRAT/StateView, <br />StateDMI, StateMod, StateCU, and the groundwater model. The procedures for MODFLOW <br />use are currently being reviewed by the State. Therefore, MODFLOW will not be addressed <br />in detail in this task. The resulting documentation will include: <br />1. A description of the HydroBase data used in modeling, to be used as an initial inventory <br />of data and procedures. For example, this documentation will indicate the HydroBase <br />data that are used as input to StateCU and StateMod and will indentify the steps <br />necessary to process data from HydroBase into its final form for modeling. The main <br />focus of this effort will be on StateCU and StateMod, with minimal emphasis on <br />CWRAT/StateView and MODFLOW. It is not envisioned that the Division 5 workbook <br />or other basin-specific applications will be studied at this time. <br />2. A summary of model data file conventions, including directory and file naming <br />conventions. <br />3. A summary of model network conventions, including naming conventions for nodes. In <br />particular, attention will be given to issues with relating node-based identifiers in <br />StateCU and StateMod with cell-based identifiers in MODFLOW and parcel-based <br />identifiers in StateCU. <br />
