Available for free, Flood Modeller's 1D and 2D solvers allow you to seamlessly model rivers, floodplains and urban drainage systems.

It provides users with a flexible and cost-effective range of tools for proactive decision-making to help manage our environment and the challenges associated with flood risk. It is suitable for a wide range of engineering and environmental applications, from calculating simple backwater profiles to modelling entire catchments to mapping potential flood risk for entire countries.

Integrated with third-party software including the US EPA SWMM, Deltares’ Delft-FEWS and BMT WBM’s TUFLOW, it allows users to incorporate elements of existing flood models and systems, directly within the customisable user-interface. It provides an intuitive environment for building, running and analysing flood models, and incorporates an open data file format and structure, allowing users to incorporate bespoke tools and customised workflows.

User friendly

Specifically designed to streamline the modelling process and automate repetitive tasks, its user-friendly interface and wide range of tools enable you to build and run models more intuitively than ever before.

Advanced solvers

Provides industry-leading, fully hydrodynamic 1D and 2D solvers that are designed to work independently, or together, enabling dynamic interaction between 1D and 2D models.

Fast simulation times

Developed for over 40 years, our solvers have become one of the fastest and most robust solutions available, making it an ideal choice for flood modelling applications.

Hydraulic structures

Includes a wide-range of hydraulic structures as standard, including weirs, sluices, orifices and bridges. Structures with automatic operation incorporate logical control rules.

Hydrological boundary

Provides embedded tools for modelling hydrological events, it can model both short and long-term hydrological events, direct rainfall, evaporation and infiltration, as well as water demands and abstractions.

Intuitive user interface

Incorporates a user-friendly interface that delivers an intuitive environment for building, running and analysing models. It offers superior workflows and support for multi-screen working.

Third party integration

The functionality of Flood Modeller can be extended, and linkages to pre-existing models formed, by integrating with third-party software such as BMT's TUFLOW, EPA SWMM and Deltares Delft-FEWS.

Technical support

Over 96% of our clients annually renew their support and maintenance contract for Flood Modeller as it provides extensive benefits. Whichever licensing option you select, technical support is available.

Tools and features

Flood Modeller provides users with a wide-range of tools and features as standard - all designed around user needs to improve productivity and efficiency.

Open file system

Built on an open file system, integrate Flood Modeller with your own workflows. It enables users to view and edit model data files and integrate custom tools quickly and efficiently.

 

Visualisation

A range of analysis and flood visualisation tools for spatial data are provided at no extra cost, allowing data to be shared with key stakeholders.

Flood Cloud

An innovative service that enables users of Flood Modeller, TUFLOW and HEC-RAS to seamlessly undertake flood risk modelling, at any scale, in the cloud.

No node/cell restrictions

Flood Modeller provides 1,000 1D nodes and 400,000 2D cells as standard. If your model exceeds this functionality, you can upgrade to the Unlimited Solver.

Case studies

Lowestoft Estuary Inception Modelling Study, England

Tidal modelling, England

In order to map flood risk from a potential tidal storm surge propagating up the Lowestoft Estuary and into Lake Lothing, the Flood Modeller 2D ADI solver was used to develop a two-dimensional model to incorporate the estuary, Lake Lothing and the Kirkley Stream channel.

Dam breach analysis, USA

CH2M performed dam-breach modelling using the 1D and 2D solvers within Flood Modeller to confirm hazard classification of the Lane City Reservoir dam and develop dam-failure inundation maps for an Emergency Action Plan.

Inundation flood mapping in Boston, USA

Inundation mapping, USA

Flood Modeller was used to map the possible effects of forecasted precipitation, sea level rise (SLR), storm surge and river dynamics in and around the Boston Water and Sewer Commission’s service area for the present and future years within a risk management framework.

Flood modelling of the Parramatta River in Sydney, Australia

Flood mapping, Australia

Flood Modeller's industry-leading 1D and 2D solvers have been applied to simulate combined fluvial and direct rainfall flooding in a sub-catchment of the Parramatta River in Sydney, Australia.
