of freeboard. A water depth of less than 3.00 feet works for all slopes thereby making the design <br /> channel cross-section the following: <br /> • Total Depth: 5.00 Feet <br /> • Bottom Width: 10.00 Feet <br /> • Side slopes: 4:1 <br /> • Freeboard: 2 Feet <br /> • Manning's n: 0.030(grassed slopes) <br /> The computer runs are all included in Appendix 1. <br /> Energy Dissipation <br /> Thereare several design features that were included to accommodate Brookfield. Some were discussed <br /> previously. Four of these relate to erosivity of flows along steep slope and mitigation of the energy <br /> leading to erosiveness. All are summarized below and a discussion regarding erosivity of flows along <br /> steep slopes and mitigation of energy leading to erosiveness is also given below. <br /> • Respecting Brookfield on property drainage paths (discussed previously) <br /> • Deep cut along the south property line (discussed previously) <br /> • Appropriate Channel Cross-Sections carrying design flowrate (discussed previously) <br /> • Increase of channel dimensions to accommodate energy dissipation and protection from erosive <br /> forces <br /> • TRM—CDOT Class 3 <br /> • Rip Rap along bank next to Brookfield <br /> • Drill Seeded <br /> • Check Dams <br /> • Hydraulic Jump <br /> • Availability of General Shale equipment and personnel for maintenance and repair <br /> Increase of Channel dimensions <br /> Channel dimensions were increased to handle the installation of riprap and other protective <br /> measures for erosive forces. The underlying datum dimensions are: <br /> o Bottom width: 14 feet <br /> o Total channel vertical height: 7 Feet <br /> These were not altered as various parameters were added. Riprapping everything proved to be <br /> prohibitively expensive so a combination of various elements was included. <br /> 10 07/30/2017 <br />
