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.:

The table below highlights some of the commonly used check files when reviewing 1D culverts. Although this list may not be all the check file you could use to review 1D culverts it is certainly a good starting point. The full list of TUFLOW check files can be found <u>[[TUFLOW_Check_Files | here]]</u>. <br>
