EAS work with a preferred partner, who provide specialist flood modelling services when required, to accompany our Flood Risk Assessments. Modelling programmes such as Flood Modeller, TUFLOW and HECRAS are used to model simple channels to large complex river systems, floodplains and urban drainage systems. Either 1D, 2D, or 1D-2D linked models of the channel and floodplain can be produced depending on the site requirements.
