It contains an inventory of the <br />various needs for such a system as communicated by a wide variety of water users, and describes the <br />models, data, user interfaces, and system architectures required to support these needs. Preliminary cost <br />estimates for the CRDSS were also made. <br />Design and Development (1994-1998). <br />Phase I (January 1994 - May 1994). <br />Phase I was the discovery, evaluation, and preliminary design period of the CRDSS project, and was <br />approximately 4 months in duration. Phase I involved an inventory of existing databases, basin simulation <br />models, water resource planning models, and consumptive use models. After the inventory was <br />complete, databases and models were evaluated. The products of Phase I were a database roadmap, <br />and recommended models for basin simulation, water resource planning, and consumptive use. The data <br />required for the models were identified and cross-referenced against the database road map. <br />Phase Ila (May 1994 -January 1995). <br />Phase II consists of the remainder of Years 1 (Phase Ila) and 2 (Phase Ilb). The early part of Phase II <br />consists of detailed design and model porting. The latter part involves implementation of the models and <br />population of the databases. <br />The CRDSS database will be designed with the flexibility to incorporate additional types and amounts of <br />data. A prototype system will be designed to demonstrate "proof of concept" for the following models (and <br />
