Data

Flood map data from the DST and Animations are stored in ESRI ASCII raster format. Each data file contains the maximum water depths for each model run. Units are in meters. These data can be uploaded to standard GIS packages, such as ArcGIS or QGIS, using the Spatial Reference EPSG:27700 (OSGB 1936 / British National Grid). Data for each location has been stored in a single archive file (e.g., .zip).

These data are FREE to use, however access to the download files requires a username and password

If you would like access please contact Prof Andy Plater who would be happy to deal with your request.

1. Download data
Data are supplied in two archive formats (i.e., each archive file contains all the individual data files compressed into one file); .zip (Windows users may prefer this archive type) and .tar.gz (Linux users may prefer this archive type)

North West model run data are not available online due to the size of the data

2. File naming conversion

The model scenarios were based upon combininations of 16 Extreme Water Levels (EWL) and Sea-Level Rises (SLR).

EWL: 1:1, 1:2, 1:5, 1:10, 1:20, 1:25, 1:50, 1:75, 1:100, 1:150, 1:200, 1:250, 1:300, 1:500, 1:1000 and 1:10000 years.
SLR:  0.0 m to 2.0 m in 10 cm increments, followed by 2.25 m to 2.5 m in 25 cm increments (Note: Fleetwood range is 0.0-1.0m).

output_Return1.max (SLR 0.0m EWL 1:1)
output_Return2.max (SLR 0.0m EWL 1:2)
.....
output_Return15.max
output_Return16.max (SLR 0.0m EWL 1:10000)
output_Return17.max (SLR 0.1m EWL 1:1)
.....
output_Return560.max (SLR 5.5m EWL 1:10000)

3. Data format

The individual data files are stored in a ESRI ASCII raster format.

NCOLS (Number of cell columns)
NROWS (Number of cell rows)
XLLCORNER (X coordinate of origin)
YLLCORNER (Y coordinate of origin)
CELLSIZE (cell size)
NODATA_VALUE (The input values to be No Data in the output raster)
ROW 1
ROW 2
.....
ROW N

ROW 1 of the data is at the top of the raster, ROW 2 is just underneath ROW 1, and so on.
