Evaluation of 2D Hydraulics Models to Improve Scour Predictions and Countermeasures
| 项目名称： | Evaluation of 2D Hydraulics Models to Improve Scour Predictions and Countermeasures |
| 摘要： | Despite major advances in predicting the spatial and temporal scales of scour at bridge crossings, bridge failure due to hydraulically induced scour still represents a major technical, economical, and societal challenge. To address this challenge, the proposed research will pursue the following specific objectives: (1) identify the key capabilities and limitations of the 2D depth-averaged numerical models when simulating scour phenomena at bridge foundations; (2) compare the performance of 1D numerical models to that of 2D numerical models when simulating scour phenomena at bridge foundations; and (3) develop recommendations for predicting scour depths and for evaluating scour mitigation countermeasures at bridge foundations using 2D numerical models. Results from the proposed research will primarily contribute to achieve better predictions of the scour phenomena at bridge foundations, as well as to enhance the design of countermeasures for scour mitigation. Additionally, through the deployment of a novel fiber-optic scour monitoring station, this research will provide new insights on the dynamic development of the scour hole using field data. Such information will effectively enhance the development, and thereby the predictive capabilities of numerical models when use to examine the impact of unknown or extreme hydrologic events. |
