In this study, in order to establish the criteria for evaluation of importance by the type of facility specialized for agricultural reservoirs, an expert groupconsisting of a total of 167 members who were in management, or specialized in the fields of design, research, and diagnosis were organized, andthe importance for facilities was set with application of the AHP technique. The importance of dam body, spillway, and intake structure composinga reservoir were set at 59%, 24%, and 17%, and the importance of dam crest, upstream slope, and downstream slope constituting a dam body wasset at 32%, 31%, and 37%, respectively. In addition, the importance of approach channel, regulated channel, chute channel, and stilling basin consistinga spillway was set at 15%, 44%, 26%, and 15%, and the importance of inclined conduit and outlet conduit consisting an intake structure was set at35% and 65%, respectively. The safety grade of the reservoirs evaluated by applying the newly presented importance values in this study showed therearrangement of the grades with a change of 11% compared to the previous grades. In this way, the newly established criteria are expected to beutilized as basic data with strategic importance in reservoir safety management and disaster prevention as well as the operation of systems in the future.
Abstract
In this study, in order to establish the criteria for evaluation of importance by the type of facility specialized for agricultural reservoirs, an expert groupconsisting of a total of 167 members who were in management, or specialized in the fields of design, research, and diagnosis were organized, andthe importance for facilities was set with application of the AHP technique. The importance of dam body, spillway, and intake structure composinga reservoir were set at 59%, 24%, and 17%, and the importance of dam crest, upstream slope, and downstream slope constituting a dam body wasset at 32%, 31%, and 37%, respectively. In addition, the importance of approach channel, regulated channel, chute channel, and stilling basin consistinga spillway was set at 15%, 44%, 26%, and 15%, and the importance of inclined conduit and outlet conduit consisting an intake structure was set at35% and 65%, respectively.
