Flood Modeller

Seamlessly model river, floodplain and urban drainage systems using Flood Modeller's industry-leading 1D and 2D solvers.

Flood Cloud Laptop.png

Flood Cloud

Instantly run all your simulations at once and deliver your modelling projects faster and more cost-effectively


Dynamically link the Flood Modeller 1D solver with TUFLOW (2D), it’s 1D component (ESTRY) as well as the new 2D HPC solver which utilises GPU technology.


Where pipe networks overflow in SWMM, links to Flood Modeller and can be incorporated to model the resulting surface flows and possible flood scenarios.

FEWS Adapter

Flood modeller integrates with Deltares' flood early warning system (FEWS) to provide a state-of-the-art hydrological forecasting and warning system.

Our software is trusted by government, utilities, insurers, universities, consultants and members of the public .

1D modelling

River Danube

Navigation improvements, Romania

The purpose of this project is to identify solutions to ensure navigation conditions of the River Danube, in particular to improve the depth and width of the navigation fairway.

River Spey, Scotland

Flood forecasting, Scotland

Jacobs are working extensively with the Scottish Environment Protection Agency (SEPA) in Scotland (United Kingdom), to help develop and improve SEPA’s flood warning systems.

ISIS was the core modelling tool used within the Rio Salado Master Plan project in Argentina

Master planning, Argentina

Our 1D solver was used within the Rio Salado Master Plan project in Argentina. The study area was the 170,000 km2 Rio Salado Catchment to the south and west of Buenos Aires.

Flooding of the Tonle Sap, a tributary of the Mekong River in Cambodia

Basin planning, Mekong

The Mekong River Commission has used Jacobs' flood modelling software for over 10 years to inform decision makers on the likely impacts of development scenarios.

Taihu basin

Scenario analysis, China

In order to understand the potential flood impacts and responses, 1D modelling for the Taihu Basin Authority was carried out to generate credible evidence of flood risk.

Modelling the Têt, France

BRL Ingénierie modelled the River Têt and its tributaries in order to develop a flood risk management plan. The study modelled 25km of river covering an area of 45km2.

Somerset levels and moors, England

Scenario analysis, England

Black & Veatch modelled the Somerset Levels and Moors, a managed catchment which is controlled by a network of structures and pumping stations.

River Clyde Flood Management Strategy, Scotland

Catchment plan, Scotland

Glasgow City Council commissioned the River Clyde Flood Management Strategy to develop a long-term plan to address potential flood risk along the River Clyde. Catchment-wide modelling was carried out using our 1D solver.

1D modelling, England

1D modelling, England

Flood Modeller Pro’s 1D solver was used to help assess and design components of the London 2012 Olympic and Paralympic Games park infrastructure.

2D modelling

2D modelling, Dubai.png

Flood mapping, Dubai

Flood Modeller's 2D ADI solver was used to perform the flood risk analysis for this project due to the complex flow patterns in the urban environment.

Integrated catchment modelling, USA

Jacobs developed a coupled SWMM-Flood Modeller 2D model to identify locations at risk of flooding when the subsurface drainage system exceeds capacity.

ISIS 2D outputs represented in the area of the proposed water control structure

Catchment planning, Argentina

A geomorphological study was undertaken for the Pilcomayo River basin to provide secure access to Pilcomayo water resources for both Argentina and Paraguay.


Dam breach analysis, USA

Jacobs performed dam-breach modelling to confirm hazard classification of the Lane City Reservoir dam and develop dam-failure inundation maps for an Emergency Action Plan.

Yanga National Park, Australia

Flood mapping, Australia

To understand the extent of flooding for Yanga National Park, an area covering 760 km2 in Australia, the 2D FAST solver was used as an environmental water management tool.

ISIS 2D flood modelling outputs displayed within ISIS MAPPER

Flood mapping, Canada

A flood mapping study for the Grand River watershed in Ontario was carried out to produce fluvial flood outlines and flood depths, taking into account property damages.

Inundation flood mapping in Boston, USA

Inundation mapping, USA

Forecasted precipitation, sea level rise, storm surge and river dynamics in and around Boston for the present and future years has been mapped using the 2D FAST solver.

Lowestoft Estuary Inception Modelling Study, England

Tidal modelling, England

To map flood risk from a potential tidal storm surge propagating up the Lowestoft Estuary and into Lake Lothing, the 2D ADI solver was used to develop a model.

Forsyth County GA USA

Watershed modelling, USA

Jacobs have modelled and mapped the existing and future conditions floodplains for all flooding sources on a watershed by watershed basis using Flood Modeller.

Visualising flood depths and velocities in the Marikina, Philippines

Risk mapping, Philippines

The Philippines Department of Science and Technology has initiated the Nationwide Operational Assessment of Hazards programme to help manage flood risk.

Cobbinshaw reservoir

Breach analysis, Scotland

British Waterways Scotland (now Scottish Canals) requested that a breach analysis of Cobbinshaw Reservoir should be carried out to reassess the dam category.

National flood mapping, Scotland

Flood mapping, Scotland

SEPA produced a national surface water flood map to cover the whole of Scotland; 78,000 km2. The map complements the fluvial and coastal maps already available.

1D-2D modelling

Flood modelling of the Parramatta River in Sydney, Australia

Flood mapping, Australia

To evaluate the impact of development on surrounding water levels, fluvial and direct rainfall flooding was modelled in a sub-catchment of the Parramatta River.

The Office of Public Works in Ireland is undertaking an in-house Catchment-based Flood Risk Assessment and Management (CFRAM) Study of the Suir catchment in Ireland as part of the National CFRAM programme

Catchment study, Ireland

The OPW is using Flood Modeller and TUFLOW to identify and map the potential existing and future flood hazard and flood risk areas for a range of annual exceedence probabilities.
