4. Flooding: the most costly natural hazard in the UK Concern of many LWEC partners Prioritisation of critical knowledge gaps by LWEC Flooding Research Strategy Pitt Review illustrated need for natural science research on extremes

5. Flooding from Intense Rainfall Programme Objective Reduce the risks of damage and loss of life caused by surface water and flash floods through improved identification, characterisation and prediction of interacting meteorological, hydrological and hydro-morphological processes that contribute to flooding associated with high-intensity rainfall events. Programme will last for five years Comprise of three work packages WP1 & 2 during first four years WP3 in years four and five

6. Flooding from Intense Rainfall WP1 Improve the length and forecast accuracy of the occurrence and intensity of rainfall associated with convective storms. The research will focus on: Extracting maximum information from new and existing observation sources; Improving techniques for small scale data assimilation within multi-scale environments; Developing methods to quantify and reduce error growth within models.

7. Flooding from Intense Rainfall WP2 Identify the susceptibility to high-intensity rainfall of different catchment types. The research will focus on: Historically assessing selected catchments with suitable archived data where flooding associated with significant responses to high intensity rainfall; Parameterizing the increased complexity of the hydrological cycle under extreme conditions; Physically observing hydro-morphological dynamics within field experiments;

8. Flooding from Intense Rainfall WP3 Enhance flood risk-management through the development of both flood risk estimation and real-time forecasts of floods associated with high-intensity rainfall. The research will focus on: Modelling the rainfall inputs to pluvial and flash flooding; Incorporating morphological, sediment and debris dynamics in flood prediction, including pluvial and flash floods; Developing and enhancing risk management solutions.
