flood_stats |
Either a data frame of flood analysis results, by gage or by county, or a list of both data frames. |
category |
Character string of the flood magnitude category to be used for mapping (one of "minor", "moderate", "major", or "extreme"). This parameter only works when mapping county-level, rather than gage-level, values. |
A map of the state(s) analyzed showing counties and gages color coded based on flood magnitude, depending on the type of data in flood_stats. Gage flood thresholds are "None" (flood_ratio < 1), "Minor" (flood_ratio < 1.5), "Moderate" (flood_ratio < 2), "Major" (flood_ratio < 5), and "Extreme" (flood_ratio > 5). For county aggregate maps, flood exposure is assessed based on the percentage of gages in the county at or above a specified flood threshold. Exposure categories include "Low" (0 (40
