## Hydrological modelling

Herrington Consulting can draw upon many years of experience using mathematical
models to study and predict coastal and fluvial flooding. Of particular relevance
to flood risk assessments is our familiarity with software packages such as
FEH, WINFAP and ReFEH, all of which can be used in conjunction with each other
to make predictions of peak river flow for any given return period. Through
the use of other hydraulic modelling techniques (described below) it is then
possible to calculate flood depths at a particular site or study the impact
of development proposals.+
