Typical Channel Profiles Measured in Upper Diversion Structure (UDS) <br />Based on the surveyed channel geometry, the current UDS was modeled with a 2 -ft bottom width and 2:1 <br />side slopes in the WinTR -55 model run JD6 CC_CP- 03.w55. The planned UDS was modeled with a 2 -ft <br />bottom width and 3:1 side slopes in the WinTR -55 model run JD6_PC_CP- 0Lw55. Model results are <br />presented in Section 5.2 (channel capacity) and 5.3 (channel stability). <br />The UDS will be reconstructed with a 2 -ft bottom width and 3:1 side slopes (Plate 3). The location and <br />disturbed area for the planned UDS is identical to the current UDS. The reconstruction will include <br />regrading the side slopes, regrading portions of the bed slope, and installing drop /check structures at six <br />locations, as shown in Plate 3. <br />4148A.131028 Whetstone Associates <br />
