waterRIDE™ FLOOD Manager

Intuitive Interrogation and Visualisation

Using waterRIDE™ FLOOD Manager, 1D models are made to look two dimensional with realistic (and interactive) animation of flood behaviour over a georeferenced background.

Regardless of the model type (1D or 2D), you can access your model results in the same intuitive and highly visual manner!

(the image to the right shows a 1D MIKE11 model, with the cross sections overlain on the interpolated water surface)

Interrogate Your Model Results at Any Location

View results as static and time varying thematic maps (including peak values across all time steps) of:

- terrain

- water level

- depth

- velocity

- velocity times depth

- hazard

- energy

- Froude No.

- bed shear

- unit stream power

This allows you to interrogate all hydraulic parameters at any location in the floodplain, not just at model nodes or cross sections.

Interactive Animation

Realistic, interactive animations are invaluable in understanding flood behaviour.

Interactive animations can be paused at any time to interrogate the active results or any GIS layers. They are not "movie files".

Full GIS controls are available during animation (eg pause, zoom into an area of interest, then restart the animation).

Interactive animations are particularly valuable in community education and emergency planning.

Time Series Plots

Clickable "time series plots" at any location allow the user to readily navigate to particular time steps in the animation.

Save and load your time series points for comparison between different model runs.

Plot various hydraulic parameters on the one plot (eg depth, velocity and velocity times depth)

Profile Plots

Profile plots of any parameter provide valuable insight into hydraulic behaviour.

Export the profile to your spreadsheet application.

Translucent thematic mapping enables the visualisation of thematic surfaces and underlying imagery, simultaneously.

Flow Hydrographs at Any Location

Flow plots across any user defined section allows the user to visualise the time variance of flow at any location in the model.

Quick Mannings Calculations

Quickly carry out calculations using Mannings' Equation to verify modelling results or determine unknown hydraulic parameters, eg:

- use stage and slope to determine average velocity and flow,

- use water level and flow to get slope and average velocity,

- use flow and slope to determine water level and average velocity

Customisable Flood Hazard Mapping

Flood hazard (velocity x depth) can be converted to a cadastral format, instantly defining flood hazards for each cadastral lot.

Set up your own flood hazards categories (charts) to provide ultimate flexibility.

Difference Mapping

waterRIDE™ FLOOD Manager can be used to easily produce difference plots. Difference plots can be used to thematically display the difference between two model runs (eg in development impact assessments with 'before' and 'after' model results).

The model results do not even need to have the same network layout or even be from the same hydraulic model!

Parameter Queries

Full Boolean logic query functionality for your hydraulic results set, at any time step or across the entire time series.

For example, display all points in the floodplain where velocity > 1.0m/s and depth > 1.0m at any stage during the flood.

Facilitates ready classification of your floodplain (floodway, flood storage, flood fringe etc).

(time to inundation query)

Time Based Queries

Execute flexible (user defined) time based queries using any hydraulic parameter to derive time dependent surfaces such as:

• time to / duration of (eg time to inundation)

• time to peak

• duration threshold (eg how long is bed shear > specified value)

Interrogate the results across the entire floodplain.

An absolute necessity for effective emergency management planning and flood hazard/risk analysis!

Enhanced GIS Integration

Combine your GIS datasets with your model results in even more sophisticated ways.

Populate a GIS field with any hydraulic parameter for all objects in the GIS file (eg automatically mapping peak flood levels to all properties in the floodplain).

Interact between GIS fields and the hydraulic data to calculate derived data (eg depth above floor level, freeboard to floor level, how long until the low points on evacuation routes are reached etc)

(thematic map of depth above low points on evacuation routes)

Exporting to Conventional GIS

Automatically export flood extents to GIS with sophisticated processing options:

• engineering flood extents

• smoothed flood extents

• noise reduction through removal of ponds, puddles and islands (particularly useful when mapping to flat areas in a DEM derived from ALS - Aerial Laser Survey)

Export any surface as a vector or raster GIS layer.

Flood Damages

Quickly and easily calculate flood damages for both individual properties and the community as a whole.

Separate flood damages into components using any number of dwelling types (eg residential, commercial, industrial etc).

Calculate the Average Annual Damage (AAD) for a community.

Carry out a Net Present Value (NPV) analysis on your flood damages.

The comparative analysis feature allows you to compare various floodplain management options and carry out Benefit/Cost analysis.

Flood Forecasting

Utilise a library of design flood surfaces to derive a predicted flood surface based on a forecast flood level at a gauge (or number of gauges).

The flood surface will be warped to fit predictions at numerous gauges to account for differing degrees of flooding in different parts of the floodplain.

The surface is automatically mapped to the DTM to provide indicative flood depths and flood extent, and integrated with GIS datasets to help assess the consequences of forecast flooding.

Flood Planning Level

Automatically calculate a flood planning level for all cadastral lots (in a GIS file) in the floodplain (eg the 1 in 100 year ARI level +0.5m).

Export the levels to your corporate GIS package for use by others.

Automated Flood Certificates

The GIS capabilities of waterRIDE™ FLOOD Manager allow model surfaces, georeferenced property data and corporate database systems to be read and combined automatically in the production of flood certificates.

Flood certificates use standard Microsoft Word templates with keywords for the automated insertion of relevant data.

You can update your certificate formatting at any time.

Peak of Peaks (Flood Envelope)

Readily calculate the maximum of all hydraulic parameters across a number of model runs to determine the maximum "flood envelope"

For example, determine the maximum level, velocity and hazard for a 1 in 100 year ARI using a number of 1 in 100 year ARI design rainfall intensity/duration combinations.

Thematically map the source of the peak water level across the floodplain (see figure)

Rate of Rise

Interrogate the rate of rise at any location in the floodplain throughout the entire duration of the flood.

Individual Property Photos

Automatically display individual property photos for GIS property information layers.

Scale your property photos to provide a realistic visualisation of flooding at each property.

Fantastic for use in community flood awareness and education campaigns!

Metadata

Store additional information about each model surface to keep track of the source of all your model results and enhance modelling Quality Assurance.

Digital Elevation Model (DEM) Creation Tools

waterRIDE Batch comes with waterRIDE FLOOD Manager and can be used to manipulate and create Digital Terrain Models (DTM's) from various sources.

waterRIDE Batch can work with a variety of file formats, including: XYZ text and binary files, ASCII and binary GRID files, GIS files, and CAD files.

Elevation information can be processed such as excluding points, clipping points, thinning points and combining different files into one seamless DTM.

waterRIDE Batch was designed to assist users in creating digital elevation models from very large Aerial Laser Survey (ALS) data points (10's-100's of millions of points).

Import existing DEM's from 12D, AutoCAD, Idrisi, MapInfo, ESRI, ERDAS Imagine, and MicroStation.

Preparing Report Figures

Plot outputs using user defined drawing templates specifying borders, graphics, logos, text etc.

Readily export high quality images at the desired print resolution for direct insertion and annotation in reports.

Automatic GIS Integration

GIS datasets integrate seamlessly with your model results.

Clicking on an active GIS layer will automatically retrieve the field data for the selected element, along with with any model results relevant to that GIS element.

Grid or TIN Based Surfaces

waterRIDE FLOOD Manager supports both triangular irregular network (TIN) elevation models, and raster (grid) elevation models with thematic mapping of the ground surface, elevation retrieval at any point and extraction of cross-sections.

Map the model results over a fine scale DTM (such as ALS or LIDAR) to enhance flood depths, extents and hazards.

Data Management and Presentation Tools

Linking of external files (images, charts, websites, PDF's, text etc) to GIS information can enhance the value of your information.

Any file that can be opened by "double clicking" in windows explorer can be linked to values in your GIS files.

When presenting results using a well prepared waterRIDE project, you have access to all the data you need at your fingertips!
