Verification of ODOT Rock Channel Design Procedures

项目名称：	Verification of ODOT Rock Channel Design Procedures
摘要：	The Ohio Department of Transportation (ODOT) uses Rock Channel Protection (RCP), referred to as Riprap, for energy dissipation to protect against scour at the outlet of culverts and storm drains. RCP is classified by size into Type A, B, and C Rock with the type, length, and depth of protection determined by the pipe diameter and outlet velocity and are shorter than the lengths designed by other accepted procedures for a given design flow, it was determined that the actual number of sites which had scour problems at the end of the rock was small, therefore, the Ohio design lengths have proved adequate. Verification of the current procedures or a replacement methodology is needed in order to provide adequate sizing of RCP at conduit outlets. The goal of this project is that the researcher will develop tests to determine the appropriate RCP design. The objectives of this research include the following: (1) Perform a literature search of DOT's and related research. Use this information to draft a proposed modeling plan of RCP performance and improvement. This can be through scaled hydraulic modeling. Convey proposed method, support, and timeline in the Interim Report. (2) Conduct modeling and gather data. Optimize the design of RCP based on ODOT design factors and any additional factors found through the literature search. Procedures and data should be available in the final report. (3) Verify and develop equations that represent different size ranges of RCP placed at culvert outlets. These will be used as a tool for designers. (4) Verify and improve Figure 1002-4 for use of RCP at culvert outlets; utilizing the updated RCP design equations. (5) Detail all supporting tests and evidence to verify ODOT RCP sizing in a Final Report. Include estimates for the design service life of RCP
