Meet with Colorado water Conservation Board and U.S. Army Corps of <br />Engineers on April 2, 1986, to review conceptual design alternatives <br />and select probable best alternative for further study. <br /> <br />/' 2. <br /> <br />4. Deliver three final drawings and technical specifications on April <br />25, 1986. <br /> <br />The Work Plan is described below. <br /> <br />-7' <br /> <br />2. HYDRAULIC ANALYSIS <br /> <br />The hydraulics analysis phase of the assignment will include data col- <br />lection of weir hydraulics and proposed geometric design, development of <br />hydraulic criteria and design criteria, layout of an array of conceptual <br />designs, and subsequent analysis. <br /> <br />a. Analyze the design of three weirs by U.S. Army Corps of Engineers. <br />b. Analyze river hydraulics above and below each of the three weirs. <br />I <br /> <br /> <br />c. Review several existing weirs on the South Platte River and analyze <br />for hydraulic characteristics. <br />-"'...,~ <br /> <br />I <br /> <br /> <br />u <br />z <br />- <br /> <br />i <br />.. <br />.. <br />z <br />is <br />z <br />.. <br />IE <br />5 <br />~ <br />i <br />CI <br />- <br /> <br />
