The family of the GR hydrological models – Interview with Charles Perrin and Vazken Andréassian

The family of the GR hydrological models – Interview with Charles Perrin and Vazken Andréassian

Contributed by Guillaume Thirel and Maria-Helena Ramos, members of the Irstea Guest Columnist Team You may have already heard of one of the GR models developed by the Catchment Hydrology research group at Irstea in the Centre of Antony (France). Or you may have already run one of these models in your study catchments or as an exercise with your students. These models started to be developed in the 80’s, with the support of data from the Orgeval experimental basin, a 104-km²…

Flood forecasting in the UK: what should we learn from the winter 2015 floods? Interview with Hannah Cloke and David Lavers

Flood forecasting in the UK: what should we learn from the winter 2015 floods? Interview with Hannah Cloke and David Lavers

Contributed by Louise Arnal In November 2014, a HEPEX post entitled “Flood forecasting in the UK: what should we learn from the Winter 2013/14 floods?” was written by Liz Stephens and Hannah Cloke (it can be found here). This post presented the forecast lessons learnt after the winter 2013/14 floods in the UK. Two years later, progress has been made in flood forecasting, early warning and emergency response, but some challenges remain. In September 2016, the UK government Department for…

Crowdsourced data for flood hydrology – Interview with flood chasers in France and Argentina

Crowdsourced data for flood hydrology – Interview with flood chasers in France and Argentina

Contributed by MH Ramos, member of the IRSTEA Columnist Team A recent paper published in the Journal of Hydrology has drawn my attention: Crowdsourced data for flood hydrology: Feedback from recent citizen science projects in Argentina, France and New Zealand. The paper deals with the use of information from social media in applied sciences and operations, with a focus on collecting photos and videos  to better assess river flows and to improve flood mapping after severe events. It prompts reflections on the way qualitative and quantitative data can…

Flood forecasting systems around the world – Interview with Thomas Adams and Tom Pagano

Flood forecasting systems around the world – Interview with Thomas Adams and Tom Pagano

As the 1st Edition of the book “Flood Forecasting, A Global Perspective” has just been released, Thomas Adams (UCAR) and Tom Pagano (BoM) [see their bio below], editors, recall how the idea of the book was born and what they have learned when editing contributions describing national and regional flood forecasting systems from 11 different countries, as well as continental scale systems. This reference book points out challenges and ways forward to improve flood forecasting around the world. Maria-Helena Ramos…

Interactions between the meteorology and hydrology communities – Interview with Martin Best

Interactions between the meteorology and hydrology communities – Interview with Martin Best

Contributed by Maria-Helena Ramos, member of the Irstea Guest Columnist Team At Irstea, the Catchment Hydrology group working in Antony (southern Paris) has been developing research that aims at better integrating knowledge from meteorology in hydrological models and forecasting systems. In December last year, I met Martin Best, an expert scientist on land surface modelling at the MetOffice, during a workshop organized in Lillehammer by the Norwegian Water Resources and Energy Directorate (NVE), the Norwegian Meteorological Institute (MET), and the…
