About the report

The Thames Coast River Flood Hazard Engineering Investigation Report was commissioned as part of the Thames Coast Project. This Project aims to deal with issues associated with river flooding in the area as part of ongoing consultation with the Thames Coast community.

The Investigation Report backgrounds the Thames Coast environment and the methodology used to measure the nature of the river flood hazards in the Thames Coast area. The Report also provides a range of mitigation options for each community, which suggest ways in which any potential effects or threats posed by hazardous flooding areas can be reduced or prevented.
