Introduction to 2D modelling

Learning objectives

Attend our introductory CIWEM-accredited training course to gain an overview of the 2D modelling techniques available within Flood Modeller. It is aimed at users who want to learn about 2D modelling, including overland flows, breach and culvert modelling.

By the end of this course, you will appreciate the pros and cons of 2D modelling and the data required in order to undertake it. You will have a good understanding of the 2D functionality within the software and know when it is applicable to apply each solver. You will be able to use the software for a variety of modelling applications where full 2D or 1D-2D linked models are required.

The course will allow you to familiarise yourself with the various tools and features within the software, allowing you to build your own 2D model, run simulations, troubleshoot common modelling issues and interpret results.

Key benefits

  • Delivered online or in person at venues throughout the UK and Ireland.

  • Fast-track your learning and understanding of Flood Modeller.

  • CIWEM accredited - attendance contributes toward your CPD.

  • One-month Flood Modeller license provided (worth £600)

  • Limited to 10 individuals, maximising the learning experience

  • Comprehensive notes, practicals and other materials are provided

  • Post-course support is provided for two-weeks

Course pre-requisites

This course assumes a basic understanding of 1D modelling using Flood Modeller.

It is recommended that attendees complete the ‘Getting started’ guides prior to the training to ensure the best possible learning experience.

Course structure

You will cover a range of topics through the training, including:

  • Introduction to 2D modelling

  • Building a 2D ADI model

  • Running simulations

  • Incorporating roughness, topographic features, and flood defences

  • Direct rainfall/surface water/pluvial modelling

  • Multiple 2D domain modelling

  • Flood hazard mapping

  • Validating results using the 2D TVD and 2D FAST solvers

  • Embedding 1D structures within a 2D domain

  • 1D river-2D linking (high-level overview)

Additional information

The in-person version of this course is delivered in one day. The course starts at 09:30 and finishes at 17:00.


The online version of this course is delivered across two-days. It consists of four sessions, with each session being delivered across a two-hour period. Two sessions are delivered each day with the first session in the morning followed by a second session in the afternoon.

Prior to the training, you will receive a detailed document which provides all the information you need to undertake the course, including the agenda, links to the various resources, and details on how to access Flood Modeller.

Each attendee must provide their own laptop to undertake the training. However, a one-month Flood Modeller Standard edition training license (worth £600) is provided to each attendee.

This course is approved by the Chartered Institution of Water and Environmental Management and attendance will contribute toward your continuing professional development (CPD).
