<br />Risk Based Profiling System (RBPS). It is an indexing method for ranking dams in accordance <br />with weighted failure modes and consequences. RBPS could be used to create a list of dams to <br />do a more detailed FMCE. <br /> <br />A subset of risk analysis, FMCE, is simplified by qualitatively, rather than quantitatively, <br />estimating the likelihood of adverse consequences from loads on dams (static, hydrologic, and <br />seismic). It includes a comprehensive review of the engineering data, operation, performance <br />history, and record of design construction, as well as information related to the consequences of <br />failure and planned emergency procedures, by a team of experts in dam safety. The teams use an <br />"expert elicitation" process to develop an understanding ofthe most significant failure modes, <br />consequences, and any risk reductions that can be implemented with respect to a dam. One <br />session was conducted in 2000 and four have been conducted in 200 I. The sessions have proven <br />to be very successful and the process shows promise for further implementation in the program. <br />Future sessions will be planned after the implementation and screening provided by the results of <br />the RBPS. <br /> <br />A review of the RBPS was performed on a number of dams to evaluate the effectiveness ofthe <br />procedure. In fact, several of the dam safety engineers have ranked many ofthe dams in their <br />geographic area using this tool. The RBPS results provide a relative ranking of dams that should <br />receive more attention, and in some cases, less attention, in the program. As discussed in Section <br />4.2 below, based on initial reviews, an agreement was executed with the Bureau of Reclamation <br />for adapting this system for the state. An Intergovernmental Agreement with the Bureau of <br />Reclamation was issued to revise their RBPS based on program needs. <br /> <br />3.10 IPA <br /> <br />For most of the fiscal year, the Dam Safety Branch Chief position was served through an <br />innovative agreement with the U.S. Bureau of Reclamation by Doug Boyer, a highly respected <br />and experienced engineer. Through some unique resources and abilities, the Deputy State <br />Engineer was able to investigate, request, and obtain approval for an Intergovernmental <br />Personnel Act (IPA) agreement with the Department ofthe Interior, Bureau of Reclamation, for <br />an individual to provide technical leadership necessary to serve as the Branch Chief. The Bureau <br />of Reclamation funded 100 percent of the employee's salary and benefits through this program. <br />In February 2004, the individual serving as the branch chief returned to the Bureau of <br />Reclamation. However, this individual continued part-time in fulfilling the branch chief role <br />through special projects beyond the end of this reporting period. <br /> <br />4.0 SPECIAL STUDIES <br /> <br />4.1 Extreme Precipitation Study <br /> <br />The State Engineer and the Colorado Water Conservation Board (CWCB) continued the process <br />during the period to study extreme precipitation in the mountainous areas of Colorado. A <br />volunteer committee of meteorologists, hydrologists, engineers, federal and state agencies, and <br />private entities assisted in the preparation of the technical portions ofthe request for proposal. <br /> <br />10 <br />
