flow element for each Node and related sub-catchment for each basin. Data values <br /> entered into SWMM for Nodes are shown on Attachment 7. <br /> SWMM Links <br /> The heart of the routing program is the Links. Links are the conduits that transports and <br /> attenuates the combined storm hydrographs as designed by the internal workings of the <br /> software. Link values used in SWMM are also shown on Attachment 7. Values for links <br /> 1 and 2 were derived from road construction plans for Alameda Ave (JSC 2016). Links 3 <br /> and 4 are natural channels and assumed to be a parabolic shape with the dimensions <br /> shown in Attachment 7. An assumed triangle shaped ditch with a depth of 3 feet and <br /> side slopes of 4:1 was assumed for Links 4-8. Simulation output seemed to show that <br /> this was adequate. <br /> Results <br /> Attachment 8 shows the Node Inflow Summary while Attachment 9 shows the Link or <br /> Conduit flow summary. The key values in the table are the total flow at each element <br /> and link,the maximum depth at full flow and the maximum velocity. The overarching <br /> value is the flow at node 108 and 109. This is the bend where the ditch begins to run <br /> along the toe end of the mine just above the Solterra development. These flows are <br /> 308.12 cubic feet per second (cfs) and 310.60 cfs respectively. All velocities in the <br /> various channel sections are greater than 7.00 cfs; rendering them excessive. These will <br /> be addressed in the next section; design. <br /> Design Assumptions <br /> The following are the principals and design assumptions that have been carried through the design. <br /> Principals <br /> 1164 7 07/30/2017 <br />
