<li> Flow widths (conversely, blockage factors) and flow height should be updated in the <font color="blue">2d_lfcsh_...</font> or <font color="blue">2d_fcsh_...</font> inputs. This information is used to refine the structures flow area when the model grid resolution isn't fine enough to accurately do so already.
<li>The head loss across key structures should be reviewed, and if necessary, benchmarked against other methods (Recorded calibration data, HEC-RASother model solutions). Note that a well-designed 2D model will be more accurate than a 1D model, provided that any “micro” losses are incorporated.</li>
<li>TUFLOW check files should also be reviewed to confirm that the correct form losses are being applied.</li>
<li>The flow area through the structure should also be reviewed.If the overall structure flow area is not correct, then the velocities within the structure will not be correct and therefore the energy losses due to the changes in velocity direction and magnitude and additional form losses will not be well modelled.
