Table 2-5 - Catchment Descriptors for Mill Creek Descriptor Units Value AREA (ha) 900 L (km) 26 51085 (mikm) 51 URBAN (95) 5 RSMD (mm) 5 2.5 Mill Creek sub-catchment SUH derived hydrograph response to design storm Use the synthetic unit hydrograph to obtain the hydrograph response for the Mill Creek sub-catchment to the design storm (Table 2-2). Evaluate the hydrograph and comment on its key characteristics. 2.6 Comparison of Catchment response hydrographs Compare and evaluate your results for both catchments. Make sure you refer to peak flowrates, volumes, times hydrograph shapes. Consider the different methods involved in deriving the results, what errors may exist and what assumptions were made and how they could affect results. Comment on these. 2.7 Part 2 Discussion Some general points to consider - Are your results valid? How could the accuracy be improved? How do your results relate to the context of the investigation? Assumptions - Are your assumptions valid? Are the methods appropriate? What improvements could be made to develop this investigation? Uncertainty Analysis - What are the possible sources of uncertainty in the annual water budget? Which element of the water budget probably contains the largest error? Why
