Line 172:
Caution should be taken when specifying the FLC values for the two different 2d bridge features:
*2d_lfcsh: FLC attribute is the total loss '''per unit length''' (meters or feet) in the direction of flow. The FLC is applied to each face as 'FLC * cell size'
*2d_bg: FLC attribute is still the '''total form loss'''. Instead of converting it to "form loss per meter", the "Deck_Width" attribute is used to automatically distribute the total FLC to the selected faces, i.e. FLC<sub>face</sub> = FLC / Deck_Width * cell size. For bridges modelled using a 2d_bg polygon
