Operational flood forecasting system including levee performance

Heavy rainfall and/or high discharges upstream cause rising water levels in rivers and streams. Certainly in steep areas this could lead to extremely fast rising water levels and unexpected flooding in watersheds due to overtopping embankments and failing levees - causing victims and economical damage. With real time information about weather forecasts and water levels, Nelen & Schuurmans has proven to be able to develop operational Flood Forecasting Systems of watersheds with the hydrologic and hydraulic model 3Di - including warning messaging. (Parramatta (Australia) and Taiwan). Worldwide these (kind of) flood forecasting models do not yet take into account the actual performance and presence of levees - while they significantly effect flood patterns and flood risk. The idea of this proposal is to improve operational flood forecasting systems by adding actual levee performance.

Developed by Nelen & Schuurmans

This operational flood forecasting system takes real time levee performance into account. With this innovation a next step in the future of operational flood risk modelling- and crisis management will become available for areas behind levees which are in danger of flooding. In order to do this - two innovation steps are required:

TRL5. Laboratory testing of integrated system
Technology validated in relevant environment. Fidelity of breadboard technology increases significantly. The basic technological components are integrated with reasonably realistic supporting elements so they can be tested in a simulated environment. Examples include “high-fidelity” laboratory integration of components. There are already two operational flood forecasting systems running daily in Taiwan and in Australia. DAM software (including D-GeoStability) has been proven in competative manufacturing and is a well developed and known software.

See more information about this level and the TRL and SRL levels.

The main components of the system have been tested separately, and an initial integration exercise has been conducted.

How does it work?

The end-user gets its personal viewer/dashboard in the cloud (secured by password) and is able to send warning messages if flood risk becomes too high. In this dashboard/viewer the end-user can see every new update, can look back at historical results and can take a look in the future (2hrs ahead). Besides, the professional user can see the background information, like the water levels, the precipitation, the actual strength of the levees.

Limitations/conditions under which this innovation does not work or is less effective

When no data is available about precipitation, actual water levels and no highresolution Digital Elevation Model (DEM) of the test site.

Added value
The addition of the detailed presence of levees and the performance (failure modes slope stability and overtopping) of the levees in an operational flood forecasting system.
