How were the data generated, processed, and modified?
Date: 04-Oct-2006 (process 1 of 9) For each HYDROBASIN or TOPO_BASIN, a project area is built in Arc/Info 9.1 using the AML build_dem.aml. This AML builds a 2000 foot buffered Digital Elevation Model, Accumulation, and Slope grids for the basin area using the Bare Earth or Digital Ground Model Lidar grids. Clip existing WTRCRS per DRNBASIN’s attribute BASIN_NAME or HYDROBASIN area. Import WTRCRS to a personal geodatabase. For WTRCRS, add field attributes DEPTH (Short, 4) for DEM “Stream Burning” of water courses, RATE (Short, 4) for geometry accuracy rating, and NOTES (Text, 254) for additional information for each line. Create polygon Shapefiles “DEMFIX” and point “PRPT” for each basin. Add field attribute DEPTH (Short, 4) to shapefile “DEMFIX” for DEM “Stream Burning” of water courses. Add attribute “CATCHMENT” (Text, 40) to “PRPT” for joining to existing DRNBASIN Polygon Attribute Table Date: 04-Oct-2006 (process 2 of 9) Create Arcmap project per basin and add basin data.

Date: 1999 (process 1 of 1) (1) Interburden thickness data for Springfield-to-Baker interval extracted from Kentucky Geological Survey borehole database. (2) Interburden grid interpolated from data points. (3) Interburden grid added to Springfield elevation map. (4) Resultant grid was reclassified into 100-foot elevation intervals. (7) Polygons were extracted from the reclassified grid. (8) Resulting ARC/INFO coverage was converted to ArcView shapefile.

Date: 2007 (process 1 of 5) Work planned for FY 2006 includes: 1. Installation of a maximum total of four flow stations at bridges of Tamiami Trail between Faka-Union canal and County Road 92 for the collection of stage, velocity, discharge, salinity (or Specific Conductance), and temperature data. 2. Begin discharge measurements with an Acoustic Doppler Current Profiler (ADCP) or comparable instrument at these and all other bridges (or culverts) along the same section of Tamiami Trail. 3. Start developing velocity calibration ratings for all instrumented sites to calculate discharge records. 4. Begin correlation analyses to determine relations between instrumented sites and all other non-instrumented sites, in order to calculate individual flows across all bridges and culverts within the study area. Date: 2007 (process 2 of 5) Contruction, instrumentation, and data collection of seven flow stations at bridges east and west of the Faka-Union Canal for the collection of stage, velocity,
