Acqua Alta: Flooding and Flood Forecasting in Venice, Italy

Acqua Alta: Flooding and Flood Forecasting in Venice, Italy

Contributed by Luigi Cavaleri, Institute of Marine Science (CNR), Venice, Italy. Venice is sinking at a rate of 1-2 mm/y. Combined with the present rate of sea level rise, ~3mm/y, this leads to ever more critical conditions for the possibility of flooding. With half of the city now no more than 80 cm above the present mean sea level and a tidal spring excursion of about 1 metre, any small surge will imply flooding in large parts of the city. A…

CNDS Summer School on Natural Hazards & Disaster Risk Reduction

CNDS Summer School on Natural Hazards & Disaster Risk Reduction

Contributed by Siobhan Dolan, University of Reading. The Centre for Natural Hazards and Disaster Science (CNDS) held a summer school at their department at Uppsala University for early career researchers (ECR) who had an interest in learning more about ‘Natural Hazards in the Anthropocene’ and disaster risk reduction (DRR). This summer school was held on 20-24th August and had 36 ECRs attending, including myself. I am a doctoral researcher from the University of Reading and one of the 13 NERC…

Fictitious Forcings have Macondo in Trouble: A Hackathon Story

Fictitious Forcings have Macondo in Trouble: A Hackathon Story

Contributed by Georgy Ayzel.  Meteorological ensemble forecasts form the core of every system for hydrological ensemble prediction. There are multiple data sources where our meteorological ensembles could come from: historical observations, numerical weather prediction and climate models, or stochastic weather generators. Different sources serve different ways we want to communicate and deliver the information of possible runoff responses to various meteorological conditions. However, there is a source that is typically ignored in the modern landscape of ensemble runoff prediction –…

Summer 2018 in Europe: did the EFAS seasonal outlook predict low river flows?

Summer 2018 in Europe: did the EFAS seasonal outlook predict low river flows?

— this post is jointly published on the blogs of HEPEX and the European Drought Centre — Contributed by Louise Arnal (ECMWF and University of Reading), Shaun Harrigan (ECMWF) & David Lavers (ECMWF). Summer 2018 in Europe was remarkable from a hydroclimate perspective, with large regions experiencing persistent dry conditions, very little to no rainfall for extended periods, a series of heatwaves with record-breaking temperatures and numerous wildfires (in the UK, Sweden, Greece, Spain, Portugal, Latvia and Germany, among others)….
