Line 24:
<li>Calculate the ratio of the water area occupied by piers to the gross water area of the constriction (both based on the normal water surface). This value is assigned the letter J in the FHA documentation.</li>
<li>Use the FHA (1978) ''Incremental backwater coefficient for piers'' data to calculate Kp. This is the value which will be entered into TUFLOW as the form loss coefficients.

</li>
<li>Digitise <font color="blue">2d_lfcsh</font> or <font color="blue">2d_fcsh_</font> inputs using either a line or polygon feature. When applying form loss coefficients the best approach is to view the structure as a collection of 2D cells representing the whole structure, rather than being too specific about the representation of each individual cell:
