<br />HMG_TO08-A14_Long_PC 11 <br />XI. LFC MODELING: MAPLE RIVER TO THE DIVERSION INLET <br />1. Purpose: For the Diversion Channel between the Maple River and the Diversion <br />Inlet Structure, determine the appropriate meandering LFC wavelength and <br />amplitude design parameters Diversion Channel bottom widths of 200-feet and <br />250-feet. <br />2. Background: Additional H&H modeling of flow in the Diversion Channel from <br />the Maple River to the Diversion Inlet has shown that the current 300-feet wide <br />Diversion Channel can be narrow to 200-feet and still pass the project design <br />flows. A narrower Diversion Channel will require revised meandering LFC <br />design parameters. <br />3. Scope: <br />a. Task 1 - Provide analysis of the morphodynamic stability of the <br />meandering LFC alignment within the main Diversion Channel from <br />the Maple structure upstream to the Diversion Inlet structure. <br />Determine an appropriate alignment wavelength that will not tend to <br />initiate planform widening. Determine an alignment amplitude such <br />that the LFC planform is within the main Diversion Channel for 200- <br />feet and 250-feet bottom widths and 25-feet and 50-feet side slope <br />toe buffer zones. Model the recommended alignments in RVR <br />Meander model and summarize the alignments’ stability. <br />b. Task 2 – If authorized in writing, model the designed alignments from <br />the Maple River downstream to Reach 1 (to be provided by USACE) in <br />RVR Meander and summarize the alignments’ stability. <br />4. Deliverables: <br />a. Draft and Final Technical Memorandums summarizing the results of <br />the analysis and modeling. <br />b. Power Point presentation summarizing the results. <br />XII. Wild Rice River (WRR) Control Structure Design Team Support <br />1. Purpose: Participate in USACE design process and provide reviews of USACE <br />35%, 65%, 95%, and final designs of the Wild Rice River Control Structure. <br /> <br />2. Background: The USACE will design the WRR Control Structure and HMG will <br />perform local sponsor technical design reviews, provide comments, and back- <br />check comments for closeout. <br /> <br />3. Scope: Attend kickoff meeting, project team meetings, and conference calls. <br />Coordinate with USACE, PMC, and Local Sponsors. Provide 35%, 65%, 95% and <br />final review comments to plans and specifications and back-check comments <br />for closeout. Provide geotechnical, structural, electrical, mechanical, hydraulics, <br />and civil layout discipline reviews for each round of review. <br /> <br />4. Deliverables: <br />Review comments DRAFT
