Case Studies

Observed Event Modelling, Llangefni, Wales

Flood Modeller’s ReFH2.3 was used to model ungauged catchments in Llangefni, North Wales. For this project the modelling of historical flows was necessary to calibrate and validate the hydraulic model in order to develop flood risk management options for the town.

Integrated Catchment Management, Yorkshire, England

Flood Modeller's 1D urban and 2D solvers were used to understand the flooding mechanisms involving overland flow from an open channel and the subsequent overflowing of the sewer system in a small and heavily urbanised catchment.

National flood mapping, Taiwan

Fluvial flood mapping to enable scientific and engineering informed analysis of flood risk was undertaken for Taiwan. Using Flood Modeller's industry-leading 1D and 2D solvers, Jacobs developed flood mapping for the whole of Taiwan.

2D modelling of urban flooding, Dubai, UAE

A flood risk assessment for the EXPO 2020 rapid transit rail system extension involving integrated hydrologic analysis with detailed 2D hydraulic modelling of the urban areas. Flood Modeller was chosen due to its ability to accurately model complex flows in urban environments.

Complex structures and operational rules, Somerset Levels, England

A catchment scale study with over 270 km of embankments, 40 separate pumps, and long duration flood events. Flood Modeller was selected due its ability to model complex structures and their operational control and the robustness of its solvers.

County-wide flooding study, Arlington County, Virginia, USA

Flood Modeller's 2D FAST solver was used to conduct a flooding study to support the Arlington County, Virginia, Stormwater Program Risk Assessment Management Plan.

Dam-breach modelling for the Lane City Reservoir, USA

Flood Modeller's 2D TVD solver was used to undertake dam-breach modelling of the Lane City Reservoir dam. It allowed complex hydraulics of steep changes in velocity and water level to be calculated more accurately.

Flood risk modelling of a steep watercourse, Greater Manchester, UK

Flood Modeller's 1D river solver was used to accurately model a steep watercourse in Greater Manchester. It aimed to produce a baseline model for the development of an Outline Business Case seeking to protect properties at risk of flooding.

Developing a 1D hydraulic model for historical flood events, Bath, England

The HYDRIC BATH project has used Flood Modeller’s 1D river solver to create a hydraulic model of the City of Bath calibrated to represent the river geometry pre-Bath Flood Defence Scheme.

Integrated 1D-2D modelling of the Parramatta River, Australia

Flood Modeller's 1D and 2D ADI solvers have been applied to simulate combined fluvial and direct rainfall flooding in a sub-catchment of the Parramatta River in Sydney. They were selected for their speed and stability.

Integrated catchment modelling, Colorado, USA

An integrated catchment study for the Little Shooks Run drainage basin within the City of Colorado Springs. A Flood Modeller 1D urban model was used to identify areas at risk of flooding once the subsurface drainage system exceeded capacity.

Inundation flood mapping for the city of Boston, USA

Flood Modeller's 2D FAST solver was used to map forecasted precipitation, sea level rise, storm surge and river dynamics in and around Boston for the present and future years. It was chosen due to its versatility and rapid computing time.

Keadby pumping station appraisal, England

Flood Cloud enabled more than 100 simulations to be completed in two days instead of 70 days. This significant saving enabled the modellers to build more precise models with better and more accurate calibration and investigate more scenarios to gain greater confidence in their design solution.

Newton Stewart flood defence scheme, Scotland

Flood Cloud enabled more than 300 Flood Modeller simulations (1D-2D linked model) to be completed in just a few hours. Processing time was reduced from 31 days to 2.5 hours, significantly reducing the programme and cut costs for the project.

Pluvial flood risk modelling, Fingal and East Meath, Ireland

Flood Modeller's 2D FAST solver was used as part of Fingal East Meath Flood Risk Assessment and Management Study to provide a rapid assessment of potential locations where pluvial flooding may occur.
