2311 In-Stream Structures Integrity and Channel Stability Survey and Evaluation
| 项目名称： | 2311 In-Stream Structures Integrity and Channel Stability Survey and Evaluation |
| 摘要： | In order to reduce impacts on infrastructure within river floodplains, particularly bridges and hydraulic structures, river control or in-stream structures are installed to reduce the impact of peak flows from large flood events. Many of these structures were installed over 50 years prior, but are not routinely evaluated for effectiveness and/or integrity after large storm events, (100-500 year storms). Previously, two ODOT studies (1971 and 1989) have compared the effectiveness of over 20 river-control and streambank-stabilization structures near transportation infrastructure. The results of these studies provide a unique opportunity to build on and enhance the present-day understanding of long-term effectiveness of these structures to limit channel migration and maintain structural function. The proposed project would add to and enhance previous studies through geomorphic surveys and in-depth analysis of the characteristics of installed in-stream structures and stream geomorphology to inform ODOT engineers on causes of survival or failure due to large flooding events over the long term. This information will improve ODOT’s understanding of the effectiveness and integrity of river control structures and inform development of standard characteristics and methods for design and installation of resilient instream structures for protection of transportation infrastructure. |
