Text description of figure
Figure 4 presents a comparison of a present and three possible future design storms, one for each of the low, medium and high 100 year climate change scenarios. The figure is a hydrograph, showing rainfall depth as a function of time for the four cases. Each future climate design storm curve shows increased rainfall depth at all times compared with that for the present climate, with rainfall increasing with climate change. The increase is particularly significant in the peak rainfall depth, with the three future storm peaks being approximately 4%, 12% and 25% respectively above the present storm peak depth.
