Royal HaskoningDHV completed two overland flow and stormwater design projects for Randwick City Council:

Beauchamp Road, Matraville – this project involved 2D TUFLOW hydrodynamic modelling using a “direct rainfall” approach to assess existing flooding for a number of low lying residential properties.  Once the existing conditions flooding had been accurately represented by the model, it was used to help develop stormwater design improvement options to reduce nuisance flooding and later the detailed design of the preferred drainage improvement option.

Burrow’s Park, Clovelly – This project involved the assessment of erosion / scour at a stormwater outlet on an ocean front reserve near Clovelly Beach, NSW.  The project involved investigating the cause of erosion / scour, development and appraisal of a range of mitigation options and then detailed design of the preferred rock protection mitigation option.
