River Pelenna

River Modelling

Although the Environment Agency and Natural Resources Wales provide extensive flood mapping this tends to cover only the main rivers and excludes many smaller watercourses.

In addition they sometimes say that their existing river models need updating or are not sufficiently accurate to assess the flood risk to a proposed new development.

All this means that river modelling work is often required if an acceptable Flood Risk Assessment (FRA) or Flood Consequence Assessment (FCA) is to be produced.
