ambur.hva: Coastal Hazards Vulnerability Assessment

In amburhva: AMBUR-HVA

Description

The function requires four ESRI Shapefiles with properly formatted field names and attributes:

1. post-AMBUR analysis envelope transect shapefile
2. FEMA Q3/FIRM shapefile
3. NOAA/NWS MOM-AGL or USACOE SLOSH shapefile
4. NOAA SoVI shapefile

The function will generate shapefiles for five vulnerability analyses:

shoreline change
inundation
SoVI scaled
inundation/SoVI
shoreline change/inundation/SoVI

The function will generate a text file during the analysis:

parameters (a text file with analysis paramaters/variables than can be
'sourced' in R or cut & pasted in R at the R prompt)

Usage

ambur.hva(loc = "location", bufferdist = 150, bufferdist2 = 10, removeanthro = "no", 
 file1 = "path", file2 = "path", file3 = "path", file4 = "path", dir1 = "path", 
 scr = c(-1, -0.2, 0.2, 1), tscr = c(0.5, 0.2), sscr = c(0.16, 0.074), 
 sovi = c(6.77, 4.06, -1.37, -4.09))

Arguments

loc	Defines the geographic location of the study area that will be used to name the output folder tag. (optional input)
bufferdist	Buffer radius in map units that is used to search adjacent transects to collect spatial shoreline change variability.
bufferdist2	Buffer distance to convert transect lines into polygons for intersecting with inundation and SoVi data.
removeanthro	Remove transects that are classified as "anthropogenic" from the analyses.
file1	File path (in quotes) to the post-AMBUR analysis envelope transect shapefile. If left as "path" then a file will be chosen interactively.
file2	File path (in quotes) to the FEMA Q3/FIRM shapefile. If left as "path" then a file will be chosen interactively.
file3	File path (in quotes) to the NOAA/NWS MOM-AGL or USACOE SLOSH shapefile. If left as "path" then a file will be chosen interactively.
file4	File path (in quotes) to the NOAA SoVI shapefile. If left as "path" then a file will be chosen interactively.
dir1	Directory/folder path (in quotes) to store the results in. If left as "path" then a directory/folder will be chosen interactively.
scr	Shoreline change rate breakpoints in map units/year (high to low risk)
tscr	Temporal shoreline change rate breakpoints (high to low risk)
sscr	Spatial shoreline change rate breakpoints (high to low risk)
sovi	Sovi score breakpoints (high to low risk)

Details

none

Value

date and time stamped folder containing the following shapefiles:

ambur_hva_shoreline_change ambur_hva_inundation ambur_hva_inundation_sovi ambur_hva_sc_inundation_sovi

Note

Some data are available at NOAA's Digital Coastal website.
