Flood is the most devastating of all natural disasters, leading to both human fatalities and economic losses worth billions of dollars every year. Flood inundation maps play a key role in mitigating flood related losses by indicating areas that are vulnerable to floods. However, the conventional approach to creating flood maps using hydraulic modeling is resource extensive, and cannot be applied easily in rural data sparse regions in the United States (U.S.). An alternative way to produce floodplain maps is proposed in Sangwan and Merwade (2015), which uses easily accessible gSSURGO soil data to produce floodplain maps for larger regions. This community aims at providing national scale floodplain map for the entire...
These data depict the western United States Map Unit areas as defined by the USDA NRCS. Each Map Unit area contains information on a variety of soil properties and interpretations. The raster is to be joined to the .csv file by the field "mukey." We keep the raster and csv separate to preserve the full attribute names in the csv that would be truncated if attached to the raster. Once joined, the raster can be classified or analyzed by the columns which depict the properties and interpretations. It is important to note that each property has a corresponding component percent column to indicate how much of the map unit has the dominant property provided. For example, if the property "AASHTO Group Classification (Surface)...
