| Total form loss of the bridge
| FLC/2 applied to all sides of the selected cells
| A cell is selected if the polyline intersects the cell crosshair. Caution should be taken when using a "thick" line, as changes in cell size can cause it to become a "wide" line. If this occurs, the FLC attribute shouldmay need to be recalculated to avoid overestimating or underestimating losses.

| FLC applied to all sides of selected cells
| Caution should be taken when using a "wide" line. ChangesThe cell size and alignment of the 2d_lfcsh line may result in selecting too many or too few cell sizefaces in the direction of the flow. The FLC input may requireneed recalculatingto lossesbe recalculated to ensure FLC Applied x number of cell sides in the direction of flow = Total form loss.
