Land use data developed from aerial photography under GIS contract. Soils hydro_group data derived from digitized NRCS County Soil Surveys. Rainfall data obtained from SJRWMD Hydrologic Database and from National Weather Service for months of April - March of the specific year. IRL Segmentation based upon scheme develeoped by Sigua (1996) and Steward, et.al (2005) Unpublished Material vector digital data \\palfile\sjrx\ES\IRL\projects\pollutant_loads\layers\IRL_loads.mdb CIRL_1999loads PLSM input paramters consist of 2000 land-use and NRCS soil hydrologic groups from GISLIB, seagrass cluster basin boundaries developed by Ed Carter under direction of Drs Robert Virnstein, Giblert Sigua and Margaret Lasi, and rainfall for the period April 1998-March 1999. Land-use pollutant EMCs and runoff coefficients were revised in March 2004 after calibration to measured Crane Creek loadings. A BMP treatment indicator (Grid Code) identifies areas where new development is indicated from a comparison to 1989 land use. Grid Code = 0 equates to development having occurred since 1989. Treatment coefficents are to be applied to calculation of loads (30% reduction in TN, 50% reduction in TP and 70% reduction in TSS). Subsequent to the creation of the GIS data layers and for the purpose of equating watershed loading to changes in seagrass distribution, certain segments of similar conditions were combined: IR12 with IR13A & IR14 with IR15. These changes are not reflected in the segmentation feature. Data set developed to show trends in land-based, annual, pollutant loadings over time and to serve as a means of establishing interim pollutant load reduction goals (PLRGs). Loads calculated separately in spreadsheet formats. en 4/1/1998 3/31/1999 ground condition Complete As needed -80.755040 -80.319876 28.129551 27.557716 524182.406152566793.1767103048392.3812923111578.020115 REQUIRED: Reference to a formally registered thesaurus or a similar authoritative source of theme keywords. REQUIRED: Common-use word or phrase used to describe the subject of the data set. Data is for review purposes only. Any changes to data must be approved by author and Joel Steward Concentrations and runoff coefficients are based upon literature values with adjustments made based upon comparison to measured tributary loads in catchments with heterogeneous land use. The accuracy of these values for any single land use must be viewed as approximate. Use of runoff and concentration coefficients should be restricted to estimation of annual loads and not for any shorter time period unless suitably modified.
