Acqua Alta: Flooding and Flood Forecasting in Venice, Italy

Acqua Alta: Flooding and Flood Forecasting in Venice, Italy

Comments 0 Comment

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…

How writing an article can come out of the blue (KGE on log-transformed flows: a bad idea?)

How writing an article can come out of the blue (KGE on log-transformed flows: a bad idea?)

Contributed by Léonard Santos (Irstea, France). It is common to read articles in which the Kling and Gupta Efficiency (KGE, Gupta et al., 2009) or its modified version (KGE’, Kling et al., 2012) are used as a metric to evaluate the quality of streamflow simulations. They are often seen as a solution to substitute the Nash and Sutcliffe Efficiency (NSE, Nash and Sutcliffe, 1970). However, are these two criterion totally comparable? Can the KGE be used exactly in the same…

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…

Can hydrological forecasting contribute to Science & Art projects?

Can hydrological forecasting contribute to Science & Art projects?

Contributed by Maria-Helena Ramos and Louise Arnal. In 1991, L. D. James starts his book chapter stating that “[i]n content, hydrology is a science; in practice it is an art”. The discussion that follows reflects on the links between science and practice at the time of writing, questioning how much “the art of hydrology [was becoming] increasingly outdated” and highlighting the “pressure for new methods” to keep on securing decision makers in water resources planning with “sound scientific information for…
