This project is one of a number that are in competition for funding from the NERC GW4+ Doctoral Training Partnership (GW4+ DTP). The GW4+ DTP consists of the GW4 Alliance of research-intensive universities: the University of Bath, University of Bristol, Cardiff University and the University of Exeter plus five unique and prestigious Research Organisation partners: British Antarctic Survey, British Geological Survey, Centre for Ecology & Hydrology, the Natural History Museum and Plymouth Marine Laboratory. The partnership aims to provide a broad training in the Earth, Environmental and Life sciences, designed to train tomorrow’s leaders in scientific research, business, technology and policy-making. For further details about the programme please see http://nercgw4plus.ac.uk/

Flood impacts over the past two decades have affected 2.3bn people resulting in an estimated total damage cost of £500bn. The Committee on Climate Change estimates that total expected annual damages from flooding and coastal change (for the whole UK, excluding groundwater) for the present day as £1.1bn, which could increase to £1.7bn and £2.8bn by the 2080s under 2°C and 4°C climate change projections, respectively, assuming no population growth and continuing adaptation at current levels.
To mitigate the impact of flooding, various measures have been proposed to enhance the preparedness and protection of societies against flooding. Most of these measures rely on flood forecasting to deploy resources and implement actions at the right locations and times.
The Grid-to-Grid (G2G) model has been adopted operationally for countrywide fluvial and pluvial flood forecasting across Britain. Surface water flooding risk is evaluated based on matching the G2G modelled surface runoff with a pre-simulated Impact Library.
Project Aims and Methods
The project aims to develop a hybrid modelling approach, coupling with environmental observations and weather forecasting, to nowcast and forecast flooding and its impact across multiple scales (national, regional, catchment-wide, and local community) to support decision-making for different stakeholders.
The aim of the project is to dynamically link the national-scale Grid-to-Grid hydrological model (typically applied at a 1km resolution) with the detailed urban flood model (with 10m or finer spatial resolution) in highly urbanised areas to better simulate the influences of urban features (e.g. drainage network, buildings) on surface water propagation. Further, the flood modelling results will be combined with socio-economic datasets to forecast flood risk - to human safety, critical infrastructure and services, properties and communities - to develop prototype tools for alerting the public that are at high risk and support emergency response actions to mitigate the hazard impact.
The candidate will be able to discuss with the supervisors how to shape the final research direction of the project and co-design the hybrid modelling framework for real-time applications.
