Flow transitions in bridge backwater analysis
WebRelated to Flow Transition. Transition means: 1) the formal and physical process of transferring from school to school or 2) the period of time in which a student moves from … WebThis study showed that the effects of main channel roughness (nmc) and flow rate (Q) on the backwater level are much higher than those of the floodplain roughness (nfp). Bridge opening (b) with contraction (kcon) and expansion coefficients (kexp) have very little effect on the backwater level within this range of parameters.
