I need help setting up this hydrology watershed problem.
1. Develop a composite flood hydrograph for a watershed with the characteristics shown below. The rainfall depths are given in Table 1. Appendix A gives the unit hydrograph coordinates. Drainage Area = 100 square mile Time of Concentration = 3.75 hours CN=85 Antecedent runoff condition = II Storm Duration = 2.5 hours Table 1 Time (hr) Incremental Rainfall (in) Cumulative Rainfall (in) 0 0 0 0.5 0.25 0.25 1 0.75 1 1.5 0.5 1.5 2 0.5 2.0 2.5 0.25 2.25 Deliverables: a) Time to peak and peak flow for this watershed (with calculations) b) Plot of the unit hydrograph for this watershed c) Unit hydrograph ordinates in increments consistent with the AD d) Incremental runoff for each time step of the storm e) Plot of the final flood hydrograph for the storm Spreadsheets showing how the flood hydrograph was computed (associated tables) Please provide data tables as appropriate.
