Mitigation of Sedimentation at Multi-box Culverts, TR-665

The overall project objective is to systematically identify the likelihood of culvert sedimentation as a function of stream and culvert geometry along with the soil characteristics of the area drained by the culvert. The conceptualized relationships will be expressed analytically for their use in conjunction with the current culvert design specifications used by Iowa Department of Transportation (IDOT) and county engineers. The following specific goals will be integral part of the proposed study: G.1. Conduct the analysis on aerial photographs on a significant sample of 2- and 3-box culverts located in various soil areas throughout the state; G.2. Estimate the rates of sedimentation using previous aerial photographs; G.3. Conduct field surveys to accurately quantify sedimentation volumes, the origin of the materials (core analysis), and additional factors involved in sedimentation; G.4. Develop analytic relationships to capture: (a) the functional relationship between stream-to-culvert ratios and soil erodibility (b) the rate of sedimentation for various soil erodibility factors; G.5. Develop matrix for complementing the culvert design process; G.6. Review culvert design specifications and formulate provisions to account for local soil characteristics in the design of culverts.
