CM2 The Model
The Community Modelling group in Otley decided to use a hydraulic model called HEC-RAS, to represent Farnley Lane, Back Bridge Avenue, and the Wharfe Meadows Park area. This software was set up to account for local river beds, drainage systems and flood flow paths. The model also allowed for changes to the bridge and weir to be made. HEC-RAS therefore enabled the exploration of specific causes of local flooding and consideration of possible solutions that would help build resilience and manage floods locally.
Nick, the scientific modelling expert, explained to the group how – in the HEC-RAS model – a river, is divided into reaches. Each reach is then defined in detail by means of drawing transects across the reach at various intervals, with cross-sectional data along each transect.
