What's new in Flood Modeller V4.6

Arriving in early 2020, we are excited to introduce version 4.6 of Jacobs’ industry-leading river and floodplain modelling, and real-time flood forecasting software, Flood Modeller. With new functionality and enhancements designed to improve the user experience, the next release will help streamline your modelling projects.


Our award-winning Flood Cloud solution has also been updated, providing new tools and features that allow you to deliver your Flood Modeller, TUFLOW and HEC-RAS projects faster and cost effectively – providing on-demand resources in the cloud.


Enhanced 1D results plotting: The process for plotting data from your 1D networks and associated results files has been substantially revised to enable both multiple nodes and multiple results files to be selected in a single operation (calibration files can also be added to plot at this stage as well). The plot definition window has been redesigned to enable this enhanced plotting specification.


Generic rainfall runoff boundary: The generic rainfall runoff boundary has been significantly enhanced. It now offers multiple options for each hydrological component, i.e. rainfall, infiltration, transformation, unit hydrograph and baseflow. Furthermore, you can divide a catchment into multiple sub-catchments and define different methods to simulate each. The resulting flows are then combined to produce an overall net flow output, which can be incorporated into a 1D or 2D model as boundary data. The options offered for each hydrological component are globally recognised methods. Thus, this boundary provides a useful alternative to the more UK specific hydrological boundaries already included in Flood Modeller.


1D data plot: Previously if you generated a 1D data plot on a secondary screen and then reverted to a single screen display then subsequent plots would be created “off screen”. This would require a manual edit of the formsed.ini settings file. Now the Flood Modeller interface checks your setup and positions new plot windows so they should always be immediately visible.


Packaging TUFLOW models within Flood Cloud: A third option is added for packaging TUFLOW models (i.e. TUFLOW only models and TUFLOW linked models; to Flood Modeller 1D and/or ESTRY). This option is independent from TUFLOW in-built packaging functions. It should provide greater reliability (and in some cases work faster) than these. However, note that it requires a particular model file/folder structure to be setup prior to starting your simulations. This new option is not set as the default option but can be selected in the Flood Cloud settings (TUFLOW tab). An option has been added to allow TUFLOW models to run displaying the TUFLOW native progress window.


Additional enhancements: In addition to these new features we have enhanced both the user interfaces and solvers to address many minor bugs and improve workflows.


The enhancements we’ve made are a mix of items from our own development plan and suggestions made by our users (via the forum, the user conference and our support network).


We can't wait to release the latest update to Flood Modeller version, which will be with you early 2020. Watch this space!


If you have any questions with regards to the above features, or would like to suggest items for future versions, please contact our support and development team.
