He also authored or co-authored EA documents such as the real-time modelling guidance and the extension of rating curves at gauging stations.
  • He retains a very strong capability in flood forecasting and led Edenvale Young in the development more than 50 forecasting models to support river and coastal flood warning in the cities of Manchester, Carlisle, Edinburgh, Perth, Leicester, Gloucester, York, Bristol and London among others..
  • Overseas Chris has worked on projects in the US, South Africa and Australia, he was the expert modeller for the World Bank funded CRIP project in Sri Lanka between 2016 and 2018.

Chris is also a director of the Bristol Avon Rivers Trust consultancy and has developed close relationships with various rivers trusts in recent years which has included working on projects to quantify the impact of Natural Flood Risk management (NFM) interventions as well as small storage areas, constructed wetland design, river restoration and reconnection of watercourses.
