• Abstract:
  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.
