This workbook applies the Colorado Urban Hydrograph Procedure (CUHP) to estimate runoff hydrographs and design flows for urban subcatchments:

1.  To generate effective rainfall and unit hydrographs for each subcatchment, based on watershed characteristics.

2.  To create a storm hydrograph for each subcatchment including peak flows and runoff volumes for each return interval.

3.  To provide an output file of storm hydrographs that can be interfaced with EPA SWMM for use in downstream modeling.
