The purpose of this dataset is to provide the locations of sediment and pollution discharge from land into the marine environment. These are locations where the river mouth meets the sea, and thus, pollutants and sediment from land are accumulated.

Hydrologic modeling was based on the 30m resolution National Elevation Dataset (NED) from US Geological Survey (USGS.) 2. FLOWDIRECTION was estimated from 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 was run on the FlowDIR gird. 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 was run on the FlowDirection grid. This produced a dataset of all grid cells discharging to a single outflow point. This includes many tiny basins. To eliminate these tiny basins, a minimum basin size (cell count) threshold was imposed. There is a unique identified (BASIN_ID) within each file to identify the basin.5.The outflow points were determined by locating the point of maximum flow within each basin. These are identified by using the map calculator function in ArcMap, to identify the cell count for the basin that matches the maximum FlowAccumulation grid value in each basin minus 1. These locations (raster) were converted to vector point file. The resulting set of basins and pour points is valuable for summarizing the spatial threat indicators developed in subsequent steps of this analysis. 2005-10-01T00:00:00
