Floods

Seminar Session

Climate change is likely to affect everyone of us. To protect communities flood mapping is essential for managing risk and predicting future flood events. In the south east of the UK the country’s largest flood risk programme is deploying advanced high resolution technologies to capture topography and details of over 4,000 assets, while a new data format for modelling river channels is helping surveyors.

Modelling flood predictions for Great Britain under a changing climate

Paul Drury, Product Manager, Ambiental Technical Solutions Ltd

Ambiental Risk Analytics in collaboration with Landmark and Wales & West Utilities have created the first national flood map using future climate change prediction data. A new type of flood map is revealing insights into future flood hazards and enabling organisations to undertake risk management. Climate change scenarios modelled by UKCP09 indicate that Great Britain is likely  to receive rain more frequentlyand of greater intensity. As a consequence it is predicted that flood hazards will generally increase through more severe events at greater frequency, compounded by rising sea levels. This presentation will analyse the results and evaluate the impact of future flooding on potential erosion and risk to transport

As Product Manager Paul oversees the development, preparation, integration and quality assurance of Ambiental’s growing range of digital products and services. Paul has wide-ranging experience of managing technical computing and data modelling projects. He has a developed understanding of the environmental data industry and is an expert in Geographical Information Systems (GIS) with over 15 years of experience. Paul is a graduate in Environmental Sciences from Brighton University and is passionate about using technology and spatial data to tackle environmental challenges. His work with Ambiental has seen him deliver flood risk seminars and training workshops in the UK as well as internationally in locations such as Brazil and Malaysia.

Using UAV and mobile LiDAR surveys to drive efficiencies in flood defence management on the Thames

Dan Culli, GIS Consultant, Critigen/TEAM2100

Gary Nel, Managing Director, Geocurve/Team2100, Critigen/TEAM2100

The Thames Estuary Asset Management 2100 (TEAM2100) programme is the Environment Agency’s largest flood-risk programme and involves new ways to manage flood defences. With 4,000+ assets, including over 350 km of walls and embankments, the collection of geospatial information is key to our asset management approach. We looked at a variety of techniques to capture asset information and identified the use of drone technology as an enabler for efficiency, safety and data quality. We attached multiple sensors to drones to capture 3D topography, HD aerial photography and 4k video – all geospatially referenced. All data is stored and viewed in the Estuary Eye, a GIS viewer available to all team members.

Dan manages the GIS for TEAM2100 and has extensive GIS experience in federal and local government as well as the private sector. With a particular interest in enterprise GIS implementations, he ensures all GIS requirements for the programme are understood and met utilising innovative approaches and applications.

Gary Nel has over 21 years experience in the civil engineering industry, working with some of the biggest construction companies in the UK. He has been running his own engineering company since 2004. In 2011 he started using Unmanned Aerial Vehicles (UAVs) to assist in surveying and ultimately to enhance my services to my clients. He was the first person in the UK to purchase a SenseFly EBEE (a sophisticated fixed wing UAV) to assist and develop aerial surveying using photogrammetry. As an Associate Member of the Royal Institution of Chartered Surveyors (RICS), he has participated in a portfolio of prestigious survey & engineering projects including: Abberton Reservoir upsize scheme, the construction of Lowestoft Waste Water Treatment Centre, Hinkley Point C, the Broadland Flood Alleviation Project and Thames Estuary Asset Management 2100 programme (TEAM2100).

The development of a standard format for channel survey data EACSD: 2D or not 2D?

Richard Groom, Survey Specialist, Environment Agency

Dimensional river channel surveying is a specialised activity which is still carried out by ground survey techniques. The presentation will give the background as to how these surveys have been carried out, the influence of new technology and will focus on the development of a standard format for channel survey data – EACSD. The presentation will explain the reasons for its introduction and relate the recently growing acceptance of this data format by modellers.

Richard is a Chartered Land Surveyor with forty years of experience, working overseas and in the UK and working for for consultants, survey companies and government. For the last fifteen years he has been with the Environment Agency where most of his work involves commissioning and managing surveys which are put out to the private sector.
