212/19/2013ObjectivesTo develop and calibrate an HSPF*-based numerical model(s) that simulates surface water flow and groundwater recharge in the Northern District Model (NDM) domain area and the entire District. DSWM District-wide Surface Water Model.To update the existing NDM (Version 3) with recharge and ET estimated by the surface water model.

* HSPF Hydrologic Simulation Program, Fortran312/19/2013DSWM Development and CalibrationModel Development12/19/20135Segmentation and Land UseMeteorological DataOther Input Data (springs, irrigation, etc.)Characterize Land and Stream SegmentsObserved Streamflow Data/Calibration LocationsCalibrationLand Segmentation12/19/20136Basis for land segments is Districts DrainageBasin data derived from FDEP Basin-24 coverage Segment size similar to previous models: INTB and IBCAdjustments to boundaries to accommodate waterbody transition (lake vs river), tributary connections, and stream gage locationsNon-contributing segments were disconnected and assigned parameters that resulted in all rainfall inputs that dont evaporate going to recharge

Land Use12/19/20137Land UseBased on 2004 Florida Land Use from SWFWMD, SRWMD, SJRWMD, and SFWMDUsed INTB categories and procedures Categories: Forest, Grass/Pasture, Agriculture/Irrigated, Mining/Other, Urban, Wetland, Urban Impervious, WaterAggregated to model categories using FLUCCS codesImpervious categoryEffective Impervious Area = directly connected impervious areasEIA computed by percentages of FLUCCS categoriesAll impervious area combined into a single Urban Impervious category

Meteorological Data Rainfall12/19/20138Rainfall data is NEXRAD (i.e., radar-derived) data at a 2x2 km grid resolution and 15 minute interval NEXRAD data provided by DistrictRainfall inputs for PERLNDs and IMPLNDs in each model segment are area-weighted averages of the rainfall values of the pixels overlying the segment Data are stored in WDM fileA pilot study on one watershed determined that the NEXRAD data were sufficiently similar to the gage-derived rainfall database used in the INTB model to support a calibrated modelDifferences between NEXRAD and gage rainfall were observedMeteorological Data Potential Evapotranspiration (PET)12/19/20139PET data are computed (Priestly-Taylor method) at the same 2x2 km grid as used by NEXRADPET data are 1-day totals; data are available for June1995 - December 2010 PET data developed by USGS and obtained from USGS PET inputs for PERLNDs and IMPLNDs in each model segment are area-weighted averages of the PET values of the pixels overlying the segment Daily PET data were disaggregated to 1 hour time step using a seasonally varying distribution function based on the pattern of daylight at the latitude of the watershed; data stored in WDM fileThe pilot study determined that the USGS GOES PET data were very similar to the gage-derived PET database used in the INTB model; differences had minimal impact on model resultsIrrigation12/19/201310Irrigation is applied to the Agriculture/Irrigated PERLND in each model segmentAmounts based on Districts monthly water use permit data for GW and surface water pumpingAmounts separated into Spray and Drip categoriesMonthly totals disaggregated to daily using a PET deficit computed from the rainfall and PET dataData are stored in WDM filesDaily Spray amount is applied as rainfall over three hours starting at 7 AMDaily Drip amount is applied as surface inflow (not subject to interception) over six hours starting at 7 AM

Surface Water Pumping12/19/201311Surface water pumping (diversions) computed from Districts monthly water use permit databaseMonthly surface water pumping totals for all permits in a subwatershed are summed, disaggregated to a constant daily rate, and stored in a WDM fileWater is removed from the model reach in the subwatershed where pumping occursSprings12/19/201312Flow from springs are added to the model reach in the subwatershed where the springs are locatedSpring discharge timeseries obtained from USGS and WM Districts and from pre-existing modelsSprings:Crystal, Rainbow, Silver, Homosassa, Chassahowitzka, Weeki Wachee, Wekiva River watershed springs, Gourdneck, Harris,Observed Streamflow Data12/19/201313Observed daily streamflow is used to compare with simulated flow during calibrationCalibration/comparison performed at 73 gage locationsData obtained from District database, USGS, and SJRWMDData stored in WDM filesData Used to Characterize Land Areas and Stream/Lake Reaches 12/19/201314DEM land area slope, stream slope, stream channelSoils infiltrationLand use segment watershed by landuse/coverNHD stream and lake locations, sizes, connectivityExisting models conveyance system connectivity, lake and stream configuration, stream cross sections, HSPF FTABLEsUSGS - stream cross sections and rating curvesLake surveys lake FTABLEsDepth to Groundwater infiltration, target ETCalibration12/19/201315Calibration followed the standard hierarchical methodology Focusing first on the overall water balance using the LZSN (lower zone nominal storage), INFILT (infiltration index), DEEPFR (fraction of GW inflow that is lost to recharge), and major ET parameters (e.g., LZETP)Maintain reasonable differences in land-use sensitive parameters within a watershedCompare total actual ET with land-use specific target ET and adjust balance between ET and recharge as necessaryAdjust low flow/high flow distribution with INFILT, AGWRC (GW recession), and BASET (baseflow ET)Calibration (continued)12/19/201316Adjust storm shape using INFILT, UZSN (upper zone nominal storage), INTFW (interflow), and IRC (interflow recession)Comparisons between observed and simulated used in calibrationHydrographsCumulative flow graphsFlow duration graphsAnnual runoff totalsStatistics (errors at various flow regimes, correlation coefficient, NS model fit efficiency)Overview of DSWM Watersheds12/19/201317Area separated into 12 major watersheds to make model input and output manageable and reduce simulation timesHAT Hillsborough River, Alafia River, and other Tampa area watershedsCRY Crystal River, Pithlachascotee River, Anclote River, Chassahowitzka River, Homosassa River, Weeki WachiWIT Withlacoochee RiverWAC Waccasassa RiverOKL Oklawaha River, including Orange Lake area17Watersheds (continued)12/19/201318KIS Kissimmee RiverMAN - Manatee/Little ManateeMSR - Myakka and Sarasota Bay areaPCH Peace River and Charlotte Harbor areaWOK - Western OkeechobeeCAL - Caloosahatchee RiverEXT Extended area - Etonia/Rice Creeks, Lake George area, Wekiva River

Summary of DSWM Development12/19/201319Principal Inputs: NEXRAD 15-minute rainfall and daily computed PET dataset, 2004 Florida Land Use (seven categories same method as INTB);

Segmentation: average size = 44 sq miles

Irrigation Input: based on groundwater and surface water pumping data; same method as INTB

Calibration: ~75 calibration locations

ET Comparisons: within error bounds of target ET (+/- 10%) for much of the area

Model Performance: overall "fair" calibration to daily streamflow, monthly average flows show best results

Average daily correlation coefficient at all gages: 0.783The monthly flow correlation coefficients at the major gages are generally better, and are all above 0.90 (Good). Results at the smaller gages are variable, with some poor statistical comparisons and some good. Average: 0.894Errors in total flow and 25%/50% high flows are small, and flow frequency comparisons are good at higher flowsSome of the calibration error is attributable to apparent errors in the principal hydrological input (rainfall). The NEXRAD rainfall dataset appears to be lower than gage-based rainfall in the earlier years of the model calibration period (WY 1996-2006), and higher in the later years, specifically it is higher in 2004-06, and lower prior to 2004Low flow years are over-simulated and high flow years are under-simulated in many watershedsHSPF:HYDROLOGIC SIMULATION PROGRAM - FORTRANContinuous simulation modelNatural and developed watersheds and water systemsLand surface and subsurface hydrology and quality processesStream/lake hydraulics and water quality processesTime series data management and storageCore watershed model in EPA BASINSDevelopment and maintenance activities sponsored by U.S. EPA and U.S. Geological SurveyCONTINUOUS SIMULATION
