<br />I <br /> <br />I <br /> <br />I <br /> <br />4. PROJECT SCOPE <br />A. Original Project Proposal- The project was envisioned to consist of three phases which <br />were: <br />· Phase I was research and discovery of existing extreme precipitation and large storm events <br />in Colorado which generally occurred above an elevation of 5,000 feet m.s.!. <br />· Phase II was designed to develop a "State Model" for the determination of extreme <br />precipitation values which are based on the selected extreme events develop from Phase I <br />tasks. <br />· Phase III was designed to be the phase where the procedures were developed for the <br />implementation of the findings of phase II and development of methodology for using the <br />newly created "State Model". <br /> <br />Phase I was expected to be accomplished in about one-year's time. Phase I was completed in <br />May 1997. The State Climatologist's Office (SCO) inventoried and developed the EP database. <br />The SEO was to organize and conduct a workshop on modeling and the development of a State <br />EP Model at Colorado State University. The workshop was conducted on April 19, 1996. <br />Additional workshops may be organized for other components. The estimated cost of these <br />Phase I components are $50,000 - $75,000 for the inventory, and $20,000 - $25,000 for the <br />workshops (primarily for reimbursement of travel expenses of participants). Total cost estimates <br />are $70,000 - $100,000. <br />The actual cost for the satisfactory completion of phase I was $83,297 for CSU and $16,703 <br />SEO and CWCB. <br /> <br />Note: Phase I has been completed by contract with Colorado State University (CSU). The <br />findings are presented in a report titled "Final Report, Colorado Extreme Storm Precipitation <br />Data Study, Summary of accomplishments and work performed February 15, 1995 through <br />October 31, 1996" by Thomas B. McKee & Nolan 1. Doesken, Department of Atmospheric <br />Science, Colorado State University, Fort Collins, Colorado. <br /> <br />The research/development component of Phase II is necessary to understand the physical <br />mechanisms of extreme precipitation in relation to elevation, and to develop a modeling program <br />for analyzing/defining extreme precipitation. (The scope of this component was defined by the <br />workshops.) The time period could be from 3 to 5 years as presently estimated. The cost shall <br />also be defined by the workshops, and dam owners and associates will be requested to <br />contribute. After the EP analyses and modeling program are developed, the EP data will be <br />produced and correlated with historic records for verification during Phase III. The generated EP <br />data can then be used (after peer review) to develop procedures for use by practitioners. <br />Geographical Information Systems (GIS) technology is available to do this. The time period for <br />this is estimated to be 1-2 years. The cost will be defined by the scope of the project and requests <br />for proposals from the industry. <br /> <br />Total estimated time for completion of all phases is 5 to 8 years. The benefits expected from this <br />proposal are: <br />. Significant reduced costs for the design of new dams, and for upgrading spillways at <br />existing dams, to the standards contained in the regulations. <br /> <br />· Increased conservation pools in reservoirs. <br /> <br />3 <br />
