Create a report that explains your comparative analyses and summarizes your observations. Don't be too short or too long in writing your report. use the table (or something similar) shown below to report the parameter values that you used so that we can better understand your results.
Compare the results of HMS
For the different models and sensitivities performed
With the GSSHA results as applicable
Take into consideration the things listed in To Turn in List.
Compare the results from GSSHA
Between GSSHA models and parameter sensitivities
With the HMS results as applicable
Take into consideration the things listed in To Turn in List.
