Process Steps
Process Step 1
| Description: |
1. Hydrologic modeling for the USVI is based on the 30m resolution National Elevation Dataset (NED) from US Geological Survey (USGS) that was hydrologically corrected - i.e. stream/gut locations were burned (elevation reduced by 15 feet) 2. FLOWDIRECTION is calculated using the DEM. This results in a data set showing which of eight directions every given 30m cell flows. (coded as integer 1,2,4,8,16,32,64, and 128, with 1 being due East.) 3. FLOWACCUMULATION is calculating using the FlowDIR grid. This results in an integer grid reflecting the number of cells flowing into any given cell. The Flowdirection grid can be used to identify rivers (gut) locations. Any cells above a given value (such as 200) represent a potential gut location. 4. The BASIN command is run on the FlowDirection grid. The Basin tool delineates drainage basins within the Analysis window by identifying ridge lines between basins. Basin analyzes the flow direction raster to find all sets of connected cells that belong to the same drainage basin. The drainage basins are created by locating the pour points at the edges of the Analysis window (where water would pour out of the raster), as well as sinks, then identifying the contributing area above each pour point. This results in a raster of drainage basins, showing all grid cells discharging to a single outflow point. There is a unique identified (BASIN_ID) within to identify each basin. |
