The <font color="blue"><tt>Global Rainfall BC </tt></font> command applies a rainfall depth to every active cell within the 2d_code layer based on the input hyetograph. In this case it is the 'RF_FC04' hyetograph specified in the '''rainfall_stations.csv'''. The input hyetograph must be in mm/hr verse time, and is applied using a stepped approach. The stepped approach holds the rainfall constant for the time interval (i.e. the rainfall has a histogram stair-step shape). This means, for example, the second rainfall value in the time-series is applied as a constant rainfall from the first time value to the second time value. As with all rainfall boundaries, the first and last rainfall entries should be set to zero, otherwise these rainfall values are applied as a constant rainfall if the simulation starts before or extends beyond the first and last time values in the rainfall time-series.<br>
