Professional summary

Research Interests

Steven heads the Hydrological Forecasting Group at the UK Centre for Ecology & Hydrology (UKCEH). He has experience of leading collaborative hydrometeorological research projects, in partnership with stakeholders, which deliver new and lasting capability to decision-makers. He is a specialist in the real-time forecasting of fluvial and pluvial (surface water) flooding in data rich and data sparse locations, and gridded estimation of rainfall using radar and/or weather radar. He is a lead developer of the Grid-to-Grid (G2G) distributed area-wide hydrological forecasting model and supported its implementation across Britain for the Flood Forecasting Centre and Scottish Flood Forecasting Service, marking a step-change in operational capability. This has included developing probabilistic flood forecasting approaches and investigating their application to Rapid Response Catchments that are often ungauged, verification of ensemble forecast systems and reviewing approaches for snowmelt forecasting.

Steven also manages the UKCEH Models and Adapter software suite of hydrological models commonly used for operational flood forecasting in the UK and beyond (including the Probability Distributed Model (PDM), Kinematic Wave (KW) routing model, and PACK Snowmelt model) and the Hyrad Weather Radar System for storing, archiving and analysing gridded hydro-meteorological products. Currently he manages research applying G2G to support improved management of the Great Barrier Reef under eReefs programme, is Principal Investigator for the NERC funded NFLICS (Nowcasting of FLood Impacts from Convective Storms in the Sahel) project and Principal Investigator of projects under the Weather and Climate Science for Service Partnership India (WCSSP India) that are developing a Flood Hazard Impact Model for India . The latter two projects build on methods he pioneered for real-time flood impact and risk forecasting at national, regional and local scales as part of a bespoke real-time surface water flood forecasting pilot system for the Glasgow 2014 Commonwealth Games and the subsequent Surface Water Flooding Hazard Impact Model (SWF HIM) used across England and Wales by the Flood Forecasting Centre. He has experience of delivering many national training courses and workshops to operational agencies in the UK and abroad including World Meteorological Organisation courses, and helped host the 2011 International Symposium on Weather Radar and Hydrology.

Wider interests of the group include flood and rainfall frequency analysis, including the Flood Estimation Handbook suite of methods, and urban hydrology
