The purpose of the weirs was to slow and divert the flow to other <br />sections of the channel. The weirs consisted of a cast -in-place reinforced concrete foundation <br />that ran up the channel slopes (image #26, 27, 29, 30, 31). Removable, sliding weir logs were <br />installed into the reinforced concrete to adjust flow rate or divert flow when needed <br />(Images # 23). Reinforced concrete modifications (Images #32-35) were also made to the <br />existing reinforced concrete channel structure to accomodate removable aluminum weir logs <br />and divert flow. <br />This protect is substantially similar to the Sante Ana Delhi Channel Diversion Project, The <br />work was in channels, that are larger in size than the Santa mita Delhi Channel and experience <br />much grester flow (linage # 27, 31,36). over 1,5541 CY of cast -In-place reinforced concrete <br />+,vera required, which Is more than the requirment for the Santa Ana Delhi Project. The scope <br />and type of the project was similar to what is required for the Santa Ana Delhi Channel. <br />Cast -in -Place reinforced concrete' structures with metal pieces were required to modify <br />portions of the channels (similar to the Santa Ana Delhi Channel) to divert flow that was even <br />greater than what will be expected for the Santa Ana. Delhi Channel (Images # 27, 29 31, 35, <br />36). <br />For the reasons mentioned above„ this project partially satisfies the minimum experience <br />requirements for the Santa Ana Delhi Diversion Project. It satisfies 7 months of the required <br />5 years experience within the last ten years in reinforced concrete flood control channels and <br />structures, it also satisfies one of the required two projects in the last 15 years in reinforced <br />concrete frond control- The project satisfies the: requirement of one project with a flow <br />diversion structure (in this case many). <br />Included as supplementary Images are #37, 38 which show a project in Huntington Beach <br />finished in February 2007 which included a RC storm water channel for which a large RC <br />structure was constructed with tall walls like what Is required in the Delhi Channel.
