TEMPEST spatial analysis

Data sources: GIS layers compiled by Jim

• Hurricane tracks
• NOAA Hurricane surge map
• C-CAP map: Use latest static cover. Upland soils (land cover classifications : cultivated, FW wetland, upland forest/shrub). Exclude upland, not estuarine wetlands. Similar soils to Tempest, with OC that will defloculate.

Steps:

• Get overlap of Hurricane surge and CCAP map (selected classes)
• Get intersection of watersheds and hurricane tracks (tropical storms); Stormtrack database has a diameter for each leg. Apply buffer around track based on hurricane diameter.
• Calculate time periods between hurricanes.

Plots

• Map of mean hurricane frequency per coastal watershed; over SE USA (Atlantic & Gulf Coast) to show the number of watershed; & area, & frequency
• Boxplot: X-axis: individual watersheds; Y-axis: hurricane severity
• Bell-curve of area weighted flooding frequency, with TEMPEST treatment shown as percentile in the distribution. To show what is the analog to the Tempest experiment
