Flood Management

Sustainable water sensitive urban design and floodplain management are some of the most complex and controversial issues presently faced by our community. River landscapes are productive, highly valued and support a range of competing interests including industry, agriculture, housing and transport infrastructure. Historical development of floodplains has also removed vast areas of diverse natural habitat, substantially increasing the conservation value of remaining ecosystems.

Flooding and floodplain management is a field that requires the seamless integration of engineering, ecological, economic and social sciences, as decisions made on the basis of flood studies will inevitably have highly significant implications in each of these areas.

Belleng VDM is well equipped to offer a complete ranges of services in the management of small or large scale flooding issues. Our in house expertise and project management experience provides the capacity to undertake:

Reviews of historical rainfall and flooding data
Comprehensive topographical and hydraulic surveys of catchment and stream morphology
Community surveys to gauge the extent and frequency of flooding problems
Hydrological and hydraulic model development to analysis the cause of existing flood problems
Predictive modelling to gauge the impact of development projects on existing flood conditions, or to ascertain the effectiveness of proposed flood solutions
Environmental impact assessment of proposed flood solutions
Cost benefit analysis of flood management options and presentation of triple bottom line scenario analysis
Hydraulic Impact Assessment
Master Drainage Scheme

Belleng VDM maintains a full suite of hydraulic modelling software so as to ensure that the package used is the most technologically robust and appropriate for the scale and type of catchment being assessed. Additionally, we are able to prepare models and maps which can be interfaced with GIS to provide a user friendly end product, or high quality visual aid for use in community consultation. Software used includes:

hydrological modelling - XPRAFTS, XPSWMM, RORB
hydraulic and flood modelling - TUFLOW 2D, ISIS, MIKE II, HEC-RAS, MIKE 21, MIKE Flood.
GIS mapping - MAP INFO, ARC VIEW and VERTICAL MAPPER
12D, Terrain Modelling
