Am working on developing flood hazard map using the module r.hazard.flood. Whenever I try to run the module I get the following error

(Sun Mar 13 23:43:19 2016)
r.hazard.flood map=floodanalysis.alpha@edgar flood=flood mti=MTI
Traceback (most recent call last):
File “/home/edgar/.grass6/addons/r.hazard.flood”, line
145, in
sys.exit(main())
File “/home/edgar/.grass6/addons/r.hazard.flood”, line 80,
in main
resolution = (float(dict_region[‘nsres’]) +
float(dict_region[‘ewres’]))/2
ValueError: invalid literal for float(): 0:00:00.09
(Sun Mar 13 23:43:20 2016) Command finished (0 sec)

Please if I may get more help on how to use r.hazard.flood to produce flood hazard maps. thanks in advance

it looks like you are using it in an unprojected location (latitude-longitude),
try to reproject your data into a location with suitable projection.
However, the module should be able to deal with this somehow (either enable it or finish with appropriate error message), so you should create a ticket for this bug.

Best,
