3. Objectives  To 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, Fortran 312/19/2013

4. DSWM Development and Calibration

5. Model Development 12/19/20135  Segmentation and Land Use  Meteorological Data  Other Input Data (springs, irrigation, etc.)  Characterize Land and Stream Segments  Observed Streamflow Data/Calibration Locations  Calibration

6. Land Segmentation 12/19/20136  Basis for land segments is District’s “DrainageBasin” data derived from FDEP Basin-24 coverage  Segment size similar to previous models: INTB and IBC  Adjustments to boundaries to accommodate waterbody transition (lake vs river), tributary connections, and stream gage locations  Non-contributing segments were “disconnected” and assigned parameters that resulted in all rainfall inputs that don’t evaporate going to recharge

7. Land Use 12/19/20137  Land Use  Based on 2004 Florida Land Use from SWFWMD, SRWMD, SJRWMD, and SFWMD  Used INTB categories and procedures  Categories: Forest, Grass/Pasture, Agriculture/Irrigated, Mining/Other, Urban, Wetland, Urban Impervious, Water  Aggregated to model categories using FLUCCS codes  Impervious category  Effective Impervious Area = directly connected impervious areas  EIA computed by percentages of FLUCCS categories  All impervious area combined into a single “Urban Impervious” category

8. Meteorological Data – Rainfall 12/19/20138  Rainfall data is NEXRAD (i.e., radar-derived) data at a 2x2 km grid resolution and 15 minute interval  NEXRAD data provided by District  Rainfall 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 file  A 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 model  Differences between NEXRAD and gage rainfall were observed

9. Meteorological Data – Potential Evapotranspiration (PET) 12/19/20139  PET data are computed (Priestly-Taylor method) at the same 2x2 km grid as used by NEXRAD  PET 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 file  The 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 results

10. Irrigation 12/19/201310  Irrigation is applied to the Agriculture/Irrigated PERLND in each model segment  Amounts based on District’s monthly water use permit data for GW and surface water pumping  Amounts separated into Spray and Drip categories  Monthly totals disaggregated to daily using a “PET deficit” computed from the rainfall and PET data  Data are stored in WDM files  Daily Spray amount is applied as “rainfall” over three hours starting at 7 AM  Daily Drip amount is applied as “surface inflow” (not subject to interception) over six hours starting at 7 AM

11. Surface Water Pumping 12/19/201311  Surface water pumping (diversions) computed from District’s monthly water use permit database  Monthly surface water pumping totals for all permits in a subwatershed are summed, disaggregated to a constant daily rate, and stored in a WDM file  Water is removed from the model reach in the subwatershed where pumping occurs

12. Springs 12/19/201312  Flow from springs are added to the model reach in the subwatershed where the springs are located  Spring discharge timeseries obtained from USGS and WM Districts and from pre-existing models  Springs:  Crystal, Rainbow, Silver, Homosassa, Chassahowitzka, Weeki Wachee, Wekiva River watershed springs, Gourdneck, Harris,

13. Observed Streamflow Data 12/19/201313  Observed daily streamflow is used to compare with simulated flow during calibration  Calibration/comparison performed at 73 gage locations  Data obtained from District database, USGS, and SJRWMD  Data stored in WDM files

14. Data Used to Characterize Land Areas and Stream/Lake Reaches 12/19/201314  DEM – land area slope, stream slope, stream channel  Soils – infiltration  Land use – segment watershed by landuse/cover  NHD – stream and lake locations, sizes, connectivity  Existing models – conveyance system connectivity, lake and stream configuration, stream cross sections, HSPF FTABLEs  USGS - stream cross sections and rating curves  Lake surveys – lake FTABLEs  Depth to Groundwater – infiltration, target ET

15. Calibration 12/19/201315  Calibration 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 watershed  Compare total actual ET with land-use specific target ET and adjust balance between ET and recharge as necessary  Adjust low flow/high flow distribution with INFILT, AGWRC (GW recession), and BASET (baseflow ET)

16. Calibration (continued) 12/19/201316  Adjust storm shape using INFILT, UZSN (upper zone nominal storage), INTFW (interflow), and IRC (interflow recession)  Comparisons between observed and simulated used in calibration  Hydrographs  Cumulative flow graphs  Flow duration graphs  Annual runoff totals  Statistics (errors at various flow regimes, correlation coefficient, NS model fit efficiency)

17. Overview of DSWM Watersheds 12/19/201317  Area separated into 12 major watersheds to make model input and output manageable and reduce simulation times  HAT – Hillsborough River, Alafia River, and other Tampa area watersheds  CRY – Crystal River, Pithlachascotee River, Anclote River, Chassahowitzka River, Homosassa River, Weeki Wachi  WIT – Withlacoochee River  WAC – Waccasassa River  OKL – Oklawaha River, including Orange Lake area

18. Watersheds (continued) 12/19/201318  KIS – Kissimmee River  MAN - Manatee/Little Manatee  MSR - Myakka and Sarasota Bay area  PCH – Peace River and Charlotte Harbor area  WOK - Western Okeechobee  CAL - Caloosahatchee River  EXT – Extended area - Etonia/Rice Creeks, Lake George area, Wekiva River

19. Summary of DSWM Development 12/19/201319 Principal 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

69. Model Performance Summary 12/19/201369  Statistical measures of calibration indicate that many of the main river basins are fairly well calibrated at the outlets; correlation coefficients for daily flows at these gages range from 0.75 (Poor) for the Peace River to 0.91 (Good) for the Withlacoochee River, based on typical hydrology calibration criteria.  Average daily correlation coefficient at all gages: 0.783  The 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: 0.894  Errors in total flow and 25%/50% high flows are small, and flow frequency comparisons are good at higher flows  Some 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 2004  Low flow years are over-simulated and high flow years are under-simulated in many watersheds
