Calibration ofSWMM-EXTRANThe City of Jacksonville Master Stormwater Management Plan (MSMP) is a comprehensive program that was developed in phases to address flooding problems, properly manage new development, address nonpoint pollutant loading, and establish an equitable means offinancing recommended stormwater improvements
Since 1990 the United States Geological Survey (USGS) has operated a stream gage on Little Sixmile Creek approximately 0.6 miles (1 kID) upstream ofits confluence with Ribault River
Summary
As part of the City of Jacksonville Master Stormwater Management Plan (MSMP), a short-term continuous water quantity model calibration was performed for three primary stormwater management systems (PSWMSs) to verify that design storm models accurately simulated a wide range of hydrologic and hydraulic characteristics. The nine basin plans in the MSMP were completed from 1991 to 1993 This calibration was performed for the month ofJanuary 1991. Prior to calibrating the model parameters used in the MSMP to the Little Sixmile Creek gage, the peak stages computed by Camp Dresser & McKee Inc.'s (CDM's) Version of the United States Enviror>.mental Protection Agency (EPA) Storm Water Management Model (SWMM) MSMP RUNOFF and EXTRAN blocks were within 0.5 ft (150 mm) ofthe measured peak stages for all ofthe events during the calibration period, and most peak stages were v.rithin 0.2 ft (60 mm).
