Note that it is presently planned that work done during this phase will be used to plan work tasks for the <br />Phase IIb task, Policy and Water Rights Database. <br />4.A simple scenario management database that will support the prototype modeling activities. <br />This activity was coordinated with the modeling tasks and task 1.05. The objective of this task as part of <br />the prototype was simply to make sure that the proper files were available to all users of the CRDSS, that <br />original files were not corrupted, and that it would be possible to store different model runs on the <br />system. This was accomplished using features in the UNIX file system; INFORMIX was not used. <br />5.A task memorandum describing and summarizing Task 1.08 activities and results. <br />In addition to this task memorandum, additional documentation on the database and database activities <br />have been produced. These include a revised CRDSS Database Design Document , the CRDSS Users <br />Manual, and the CRDSS Developers? Manual. <br />Work Plan <br />There are subtasks in the work plan where some summary discussion is warranted. For some subtasks <br />deliverables were produced or substantial resources were spent. <br />Subtask 1. Install and Implement the Database <br />Early in Phase IIa, the INFORMIX software was installed. There were some minor delays and problems <br />because of the necessity to synchronize the supported versions of IRIX, NFS, and INFORMIX. Later, <br />there were some other problems with disk drive failures and some incompatibilities that hampered using <br />INFORMIX with raw disk. The failed drives were replaced under the respective drive warranties, and <br />some of these drives were returned to the State. The incompatibilities were resolved by the purchase of <br />three new 2-gigabyte IBM high performance disk drives. No data were lost due to the failures because <br />the development team maintained backups of the system on magnetic tape. However some time was lost <br />to replace the failed hardware and restore the file system from the tapes. <br />Database maintenance activities were performed under this subtask for Tasks 1.07, 1.08, 1.09, and 1.10. <br />Subtask 2. Review Historical Data and Populate the Database <br />The database was populated as discussed above. Quality control checks were implemented as <br />appropriate during population of the database. After population, the data were spot checked for <br />consistency with the original source. <br />Subtask 3. Fill Data Gaps Required by the Water Rights Planning and Consumptive Use Tasks <br />Part of this subtask was to inventory the data gaps found in the historical time series records. A <br />summary of this effort can be found in Appendix A, Inventory of Data Gaps for the Time Series Data. <br />Note that this inventory was done assuming that monthly statistics would be computed for a given data <br />set. The data were searched and summarized such that any month having any number of missing days <br />counted as a missing month. <br />4 <br />A275 01.09.95 1.08-2 Greer <br />
