EPSRC Studentship


Building a community understanding of flood risk through participatory modelling


Running alongside the Blue-Green Cities project was an EPSRC studentship held by Shaun Maskrey and supervised by Nick Mount and Colin Thorne at the University of Nottingham

The studentship investigated the potential of different participatory modelling tools to more actively involve local stakeholders in the modelling of flood risk. It had the following five objectives:

  1. Elicit what participation aims to deliver at different stages of the flood risk modelling process
  2. Identify the strengths and limitations of different participatory modelling tools
  3. Develop a methodological approach through which participatory modelling can be delivered
  4. Trial and evaluate different participatory tools in local flood risk contexts
  5. Develop a framework against which to evaluate the use of participatory tools

Two case studies, Hebden Bridge, West Yorkshire and Southwell, Nottinghamshire, were selected in which to trial two popular tools: Bayesian networks and system dynamics, respectively. Literature review has revealed that the affordances of these tools are suited to different stages in the flood risk modelling process (Figure 1).

The case study in Hebden Bridge ran from late-2013 to mid-2014. It consisted of six workshops attended by a mixture of local stakeholders, including non-expert residents and expert representatives from the Environment Agency, Calderdale Metropolitan Borough Council, The National Trust and others. Through a series of modelling activities, the group co-produced a conceptual model of their understanding of flood risk using Bayesian networks. The network was built around nine key ‘catchment objectives’ identified by participants (Figure 2), and investigated how different interventions might affect their achievement.

Results showed that participants prioritised the social consequences of flood above other effects of flooding, and saw a community stewardship approach to flood resilience as being the favourable route to achieving their objectives, as illustrated in the 'Change Under Each Scenario’ pdf PDF file icon.

second case study in Southwell ran in 2015. In partnership with Southwell Flood Forum, five workshops uased employ system dynamics as the participatory modelling tool. Southwell is at a much later stage in the flood risk modelling process than Hebden Bridge (Figure 1), with the community focussed on appraising options and designing solutions for reducing flood risk, the funding for which (c. £1.9 million) having recently been secured. The five workshops brought together a group of 15-20 individuals, mainly local residents (both experts and non-experts), with additional representatives from Nottinghamshire County Council, the Environment Agency and Severn Trent Water.
