Flooding / runoff by land cover.

Hi Folks

I'm doing a GIS assignment in college about flooding around Lough Erne. I know the GIS part but the environmental science bit is new to me. The Northern Ireland Centre for Ecology and Hydrology produce a land cover map that have categories like; open dwarf shrub heath, neutral grass, broad leaved woodland, continuous urban, inland bare ground etc.

Can anyone point me in the direction of information on how these different land cover categories react to flooding? Do they hold flood water, is there a metric for measuring runoff? I'd be grateful for any info.

Thanks.

hey,

I have seen a presentation from JBA http://www.jbaconsulting.ie/ who have a flood model for Ireland as well as UK.
The have land contours and land absorption built into their model, their latest model even uses LIDAR for land contours.

They might be a source of some information.
