Flood Modelling

What we do

We develop and utilise river models for a variety of applications. We are experienced in the use of Flood Modeller, HEC-RAS, TUFLOW and linked 1D-2D modelling solutions (Flood Modeller-TUFLOW/ESTRY-TUFLOW) in modelling studies of all scales.

Our expertise and technical capability allows us to develop robust models from first principles or to utilise existing models from previous studies, following review and neccesary improvements.

We specialise in modelling complex scenarios and assist in troubleshooting model performance issues for a wide range of client organisations. Our knowledge of the fundamental equations at the heart of hydraulic modelling and their application within relevant software solutions enables us to develop robust, reliable models that suitably represent mechanisms of flooding within the study area.

Since 2008/09 we have provided lectures in hydraulic modelling to Leeds University School of Geography Masters students. This work area expanded in 2010/2011 and beyond, with further lectures given to undergraduate students in the Leeds School of Civil Engineering. During May 2010 members of staff presented at the Bristol TUFLOW UK Workshop (organised by Edenvale Young in association with BMT WBM).

We aim to add value and increase efficiency within the scope of project work wherever possible, focussing on comprehensive data review and project specification when commencing studies. This guides the approach taken and data used in studies and the specification for model output from studies. Where appropriate we guide client organisations in specifying output from modelling studies to ensure that the format in which output is provided is effective, convenient and fit for purpose bearing in mind project aims and targeted end users.

We have undertaken modelling studies for the following applications:

  • Floodplain mapping (extent mapping/hazard mapping/velocity depth mapping)
  • Flood map improvements and challenges
  • Calibration studies
  • Flood Warning Area (including First Property to Flood) studies
  • Design flood modelling used for informing Flood Risk Assessment studies
  • Simulating breach of coastal and fluvial defences
  • Simulating overtopping of coastal and fluvial defences
  • Dam breach inundation assessment
  • Flood defence project appraisals
  • Gauging station rating improvement
  • Benchmarking flood forecasting models

Technical capability

  • Flood Modeller Professional by CH2M HILL with unlimited nodes licensing
  • TUFLOW 2D licensing (multi-2D domains)
  • Flood Modeller-TUFLOW link
  • MapInfo GIS and ArcGIS compatible systems for model schematisation, floodplain mapping and processing of model output
  • Through our partner organisations we have access to photogrammetry services for production of surface TIN models of dams, other asset structures or floodplain topography

Why choose us?

Public Organisations

As intelligent consultants we ensure that we at the forefront of recent thinking in flood modelling, mapping and the wider area of flood risk management. Our staff are active members of relevant modelling user groups and fully aware of requirements for technical mapping and modelling within the context of latest legislation and guidance (The Pitt Review, 2008, EU Floods directive, 2007 and the Floods and Water Management Act 2010).

We specialise in undertaking modelling studies, assisting in studies where extra support is required and troubleshooting complex hydraulic modelling problems, finding a solution that enables project aims and objectives to be met.

Our presence on Environment Agency Frameworks enables us to provide advice and technical support to the Environment Agency where required, whether this be through secondment support or carrying out standalone project tasks.

We work flexibly alongside client organisations - being equally happy to quality assure and review external modelling studies or provide guidance and input to internal and standalone modelling projects.

Client organisations are assured of working with experienced staff members with a high level of technical expertise, whist our low overheads ensure that value offered is unsurpassed.

Private Clients

Our technical capability and knowledge is at a level comparable with much larger multidisciplinary consultancies; however as a small consultancy our low overheads mean rates are very competitive.

We will guide you through the project process and ensure that the most appropriate and cost effective approach is taken to fulfil your particular requirements.

Other Consultancies

We provide guidance, quality assurance and troubleshooting services to other consultancies and are happy to act as sub consultants or assist when modelling becomes complex or if resources are stretched. Our discretion is assured when working for third parties.

Our flexibility and technical/hardware capability allow us to produce the highest quality output in short time frames.
