At it’s most basic level, the waterRIDE™ environment was designed to allow users to “get at” their datasets, irrespective of the users “technical” background.

Successful floodplain management and planning requires a thorough understanding of local flood behaviour. Occasionally, this can be garnered from actual flood events, but more commonly, this understanding needs to come from computer hydraulic models.

With traditional, common place model interrogation approaches, static “snapshots” of model results are taken at the peak of the flood and used to derive hydraulic parameters such as peak water levels, peak velocities, velocity times depth (VxD), and hydraulic hazards.

The limitation of such an approach is that it neglects the fact that a flood develops over time. This means information critical to the full understanding of flood behaviour is lost (such as isolation, rates of rise, time to inundation, time available for evacuation, duration of inundation etc). In some cases, using peak values to derive hydraulic parameters such as velocity times depth and flood hazard is misleading, as peak depth does not necessarily occur at the same time as peak velocity!

The team of engineering programmers and hydraulic modellers at WorleyParsons have developed waterRIDE™ FLOOD Manager (and Viewer) to provide floodplain managers and planners with a dedicated tool for interrogating their full time-varying model results set from any model, in a live GIS system, a feature unique to the waterRIDE™ environment.

waterRIDE™ FLOOD Manager was designed to provide floodplain managers with access to their model results in an intuitive manner providing valuable information to assist in the floodplain management process. It allows floodplain managers to leverage their investment in, and to extract more value from their floodplain modelling results, regardless of the model type used.

Models currently supported include (both 1D and 2D): TUFLOW, TUFLOW FV, MIKE11/21/FLOOD/SHE, RMA2, InfoWorks RS, Isis 2D, SOBEK, DELFT 3D, FLS, time-varying ASCII grid output, HEC-RAS, XP-STORM, EXTRAN (XP-SWMM), DRAINS overland flow, ESTRY, ANUGA, ICPR and even hard copy results.

Some of the capability available in waterRIDE™ that is applicable to Floodplain Managers includes:

Thematic Flood Surfaces – a library of design flood surfaces at your fingertips. Readily interrogate terrain, water level, depth, velocity, VxD, hazard, Froude and shear at any location in the model, for the hydrograph!

Single Interface – interrogate any of your model results with the convenience of a single interface

Plot Hydraulic Parameter Data – create time series, profile, and flow plots using the model results at any location(s) in the model.

GIS Backdrop – enhance your understanding of the model results using rich and familiar GIS datasets as backdrops.

Flood Extents – rapidly generate GIS flood extents for ready identification of flood affected properties and exporting to any GIS package, with sophisticated smoothing options.

Rate of Rise – display rates of rise at any location in the model to improve understanding of the time varying nature of your flooding issues

Floodway, Flood Storage, Flood Fringe – Boolean logic queries allow you to identify zones where velocity and depth meet certain criteria to assist with definition of floodways, flood storage areas and the flood fringe

GIS Integration – easily populate GIS layers with data from your model results (such as peak flood levels and flood hazard), or use your GIS data in conjunction with the model results to calculate values such as depth of over floor flooding, or depth over evacuation routes.

Peak of Peaks – easily calculate the peak flood envelope (water level, extent, velocities, VxD, hazard etc) from a series of model results (eg different 100yr rainfall intensities and durations).

Flood Planning Level – automatically add a buffer to peak flood levels to derive a flood planning surface, readily showing those properties within the flood planning zone and the required minimum floor levels.

Parameter Queries – query your model results for specific hydraulic criteria for identification of dangerous flooding conditions

Flood Damages – easily calculate flood damages across all flood events, for all properties in the catchment, including calculation of Average Annual Damage (AAD) and net present value analysis. Easily carry out Benefit/Cost analysis of various floodplain management options.

Metadata – tag all of your model results with additional information (such as source report, results date, comments etc) for quality assurance purposes.

Quality Assurance – Free up your time with rapid and consistent issuing of flood information, including automated flood certificates.

Share Flooding Data – share flooding information across the organisation in a quality controlled, “view only” manner using waterRIDE™ FLOOD Viewer. Different waterRIDE™ projects can be setup to convey datasets in targeted ways for different end user types.

Evacuation Planning- interactive animation of your model results in a live GIS environment allow you to visualise and interrogate how floods develop providing essential information in evacuation phasing and planning.

Flood Forecasting – rapidly interpolate a predicted peak flood surface from a predicted level at a gauge (or multiple gauges). See what a predicted flood will look like and use the predicted surface for planning and management.

Property Photos – integrate flood levels with scaled property photos to provide a realistic representation of flooding at an individual property and greatly enhance community flood awareness and understanding

Difference Mapping – clearly view the impact of proposed developments, flood mitigation options or climate change scenarios through difference mapping. The surfaces do not even need to be on the same framework (eg you could prepare a difference surface between the new 2D model results and the old 1D model results!).
