Flood Risk Assessment
A flood risk assessment explains how a proposed development will handle flood risk from all water sources to the site. It should also consider how the development might change flood risk to nearby areas and give suggestions to prevent increasing that risk.
Flood Modeller allows users to quickly and easily undertake flood risk assessments to obtain fast regulatory approval. Our flexible licensing structure means it is scalable and suitable for businesses of all sizes.
Key benefits
⟶ Flood Modeller’s powerful solvers are designed to be dynamically linked to provide accurate representation of flood risks
⟶ Consideration of diverse sources of flooding including fluvial, coastal and pluvial flood risk.
⟶ Automation tools to streamline the model build process
⟶ Quick setup of multiple model runs for different scenarios and configurations
⟶ Easy review of results to ensure current/existing flood risk is not increased or can be mitigated to gain planning
⟶ Access a GIS interface, suite of numerical solvers, hydraulic structures and the latest hydrological methods
⟶ Confidently represent flood risk for a wide range of proposed developments

Resiliency in planning and flood risk management
In this webinar, George Wade, Senior Associate Director of Urban Planning at Jacobs, discusses resiliency in planning and flood risk management. The first part of the presentation focuses on Jacobs’ integrated and collaborative approach to urban planning and the second part introduces Flood Modeller as a digital solution for flood risk management.
Quick and easy modelling
Flood Modeller enables you to confidently identify the source of potential flooding and secure fast regulatory approval.
In England, flood risk assessments are required for most developments within one of the Environment Agency’s flood zones. This includes developments within:
Flood zone 2 or 3, including minor development and change of use, or more than 1 hectare in flood zone 1
Less than 1 hectare in flood zone 1 where you could be affected by sources of flooding other than rivers and the sea (for example surface water drains)
In an area within flood zone 1 which has critical drainage problems as notified by the Environment Agency
The Scottish Environment Protection Agency, National Resources Wales, Department for Infrastructure (Rivers) in Northern Ireland and the Office of Public Works in Ireland also provide similar guidance. Additional guidance is also available on how to use modelling for Flood Risk Assessments.
The software provides everything you need to model different sources of flooding, including fluvial (rivers) and coastal (tide) sources. You can also represent urban drainage systems to consider pluvial (rainfall) flood risk. These models predominantly define subsurface pipe drainage networks, however they can include components to model both infiltration and surface water.
Flood Modeller offers specific units to represent a wide range of hydraulic structures including bridges, culverts, orifices, weirs, reservoirs, etc., providing you increased accuracy in the representation of the proposed development.
Its intuitive GIS interface allows you to visualise flows, water levels and any other variable to easily understand flood risk in your study area.
