The analysis takes into account both concentrated and distributed loading. An iterative computation procedure is employed whereby the length of the bottom cable segment and the angle of inclination of the anchor tension are initially assumed. The equations of equilibrium and compatibility are applied to each element of the assembly in a recurrent manner. The procedure is terminated when the coordinates of the uppermost joint of the guy are within a prescribed tolerance to those of the tower pin. A typical example is presented.","PeriodicalId":136288,"journal":{"name":"Journal of the Power Division","volume":"96 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1971-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132195965","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Because the spillway and powerhouse are combined into a single structure in the unique Hydrocombine concept conceived for the Wells Project, the conventional fish passage facilities could not be directly used at the Wells Project. A fish attraction system was developed by using submerged high velocity water jets at each end of the Hydrocombine to provide an attraction flow across the downstream face of the Hydrocombine. The jet locations and jet flow were developed from hydraulic model tests of the Hydrocombine structure. Two staircase type fish ladders are provided for passage of fish over the Hydrocombine, one ladder located at each end of the Hydrocombine. An extensive fish spawning facility was constructed immediately downstream from the west embankment of the dam. Located in the west fish ladder is a sorting facility for diverting selected fish to the spawning channel. A 150-acre artificial pond for rearing steelhead trout is constructed in the Wells Reservoir.","PeriodicalId":136288,"journal":{"name":"Journal of the Power Division","volume":"78 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1971-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134213381","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

With the aid of measured float tracks a coefficient n could be estimated indicating which part of the cooling water, leaving the outlet channel is flowing directly to the inlet channels. This coefficient n was found to depend on the wind direction. Also a method was found to determine the temperature in the mouth of the outlet channel. In this way a relationship could be derived between the inlet temperatures and determining wind conditions. For the power plant under consideration the relationship was compared with available records of the inlet temperature. An adequate starting point was given to determine if the existing power plant can be enlarged without creating difficult conditions for the supply of cooling water.","PeriodicalId":136288,"journal":{"name":"Journal of the Power Division","volume":"95 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1969-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129099089","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The diversion tunnel is concrete lined and has a 40-ft diam horseshoe section, 1700 ft long to handle 60,000 cfs. The three-unit power plant with 391,500 KW nameplate capacity is notched into left abutment rock and overlaps the toe of the dam. Energy of 300,000 cfs discharge over the center section spillway is dissipated by a combination of concrete nappe deflectors and a submerged roller bucket. Fish trapping facilities adaptable to the 48-ft tailwater fluctuation consist of an aluminum barge floating in the tailrace.","PeriodicalId":136288,"journal":{"name":"Journal of the Power Division","volume":"94 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1968-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131006648","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
