Line 262: * hB/T ratios of less than 1 represent a very unusual bridge sitting low to the ground, and the peak FLC may increase above the end value (FLC of 0.6) in a way that doesn't follow the research trend or extrapolation. For these cases we would recommend using CFD modelling to obtain a more informed value. Alternatively, computing an FLC based on pressure flow or using 1D culvert might be considered. * For hB/T ratios of greater than 10, the FLC is likely to continue to decrease, but probably not significantly. Clamping to the end value (FLC of 0.16) might be considered the more conservative approach (if the primary concern is flood levels upstream of the bridge).<br> <br> {{Tips Navigation \|uplink=[[ TUFLOW_Modelling_Guidance \| Back to TUFLOW Modelling Guidance]]
