			Where bends occur within one culverted length, additional losses can be applied using the form_loss attribute of the 1d_nwk layer. This applies the energy loss appropriately for a 'minor' loss using K*V<sup>2</sup>/2g. Bend loss coefficients (K) are found in many standard hydraulic references, e.g.:

	A culvert is a structure that allows water to flow under a road, embankment, railway or other similar obstruction from one side to the other. Culverts or pipe channels can be either rectangular, circular (pipe) or irregular in shape and can vary in size depending on the flow and design requirements.

	To limit the doubling up of expansion and contraction losses on a culvert (as 1D nwke culverts will already contain height, width, entry and exit coefficients) the 2D flow into and out of a culvert should be as representative of the culvert dimensions. You can achieve this by selecting the number of 2D cells that best matches the width/diameter of your particular culvert. The example below shows a 4m culvert that has used an SX line to select 2 x 2m grid cells to discharge to. Remember that the selection of a particular cell, when using a polyline, requires the polyline intersect the cell cross-hair - ~~see~~ ~~Section~~ 7.~~4 ''2D Boundaries'' within the~~ TUFLOW ~~manual~~. <br>		To limit the doubling up of expansion and contraction losses on a culvert (as 1D nwke culverts will already contain height, width, entry and exit coefficients) the 2D flow into and out of a culvert should be as representative of the culvert dimensions.
