| Summary: | A combined experimental and analytical approach was put together to evaluate the hydraulic performance and stability of TxDOT standard and modified temporary concrete traffic barriers (TCTBs) in extreme flood. Rating curves are developed for different TCTBs from the laboratory experiments and methods are developed to model TCTBs using HEC-RAS during extreme flood condition. In addition, the effect of clogging of the openings of the TCTBs is also evaluated. A parametric study was conducted with important field parameters to evaluate the effect on stability of TCTBs against sliding and overturning during extreme flood. Based on the study of hydraulic performance, stability analysis, and parametric study, it can be seen that the modified single slope barrier is the most efficient TCTB from the perspective of hydraulic performance and the low speed concrete barrier is the most efficient TCTB from the perspective of stability. A guideline is prepared to use TCTBs in flood prone zones so that the use of TCTBs will not be detrimental in extreme flood. |
