Potential future increases in flooding due to climate change need be taken into consideration when designing flood defences or planning new infrastructure housing developments. Existing guidance on allowances Great Britain was based research that developed a sensitivity-based approach estimating the impacts of peaks, which applied with catchment-based hydrological models. Here, is national-scale grid-based model, producing modelled response surfaces for every river cell 1 km grid. This...

Understanding the current hydro-meteorological situation is critical to manage extreme events and water resources. The United Kingdom Water Resources Portal (UKWRP) has been developed enable dynamic, interactive access data across Kingdom, including catchment daily rainfall (near), real-time mean river flows, groundwater levels, soil moisture data, standardised climate indices. UKWRP offers a way of exploring full range flow variability, comparing conditions those in past, from droughts...

PREDICTOR (PREDICTing flooding impacts from cOnvective Rainfall) has been developed to improve the approach forecasting of surface water flooding. is a next generation decision-support tool that utilises latest Met Office convective precipitation ensemble capabilities and Scotland’s National Flood Risk Assessment (NFRA) flood maps. The Impact-based Forecasting (IbF) combines likelihood ("the chance") flood-producing rainfall (from forecasts) potential impact NFRA) produce "Flood...

Mesoscale convective systems (MCSs) dominate rainfall and its extremes in most parts of West Africa, frequently producing flash floods that result major damage loss life. As African storms are already intensifying, these effects expected to become more frequent severe under climate-change rapid urban expansion. To help mitigate impacts, the NFLICS (Nowcasting FLood Impacts Convective Sahel) project has co-developed a prototype nowcasting system with meteorological services based on...

<p>Understanding the current hydro-meteorological situation is critical to manage extreme events and water resources. The UK Water Resources Portal (UKWRP) has been developed enable dynamic, interactive, real-time access data, including catchment daily rainfall, mean river flows, soil moisture data from COSMOS-UK standardised climate indices. Users can view at field, grid cell scale enabling holistic assessments of status a range spatial scales. portal offers way exploring full...

<p>Flash flooding from intense rainfall frequently results in major damage and loss of life across Africa. Over the Sahel, Mesoscale Convective Systems (MCSs) is main driver flash floods, with recent research showing that these have tripled frequency over last 35 years. This climate-change signal, combined rapid urban expansion region, suggests socio-economic impacts will become more frequent severe. Appropriate disaster preparedness, response, resilience measures are required...
