Gender balance in hydrology

Gender balance in hydrology

Contributed by Bettina Schaefli, a HEPEX guest columnist for 2014 At this year’s EGU in Vienna, gender balance in hydrology has (again) been heavily discussed – due to a question I raised during the business meeting of the Hydrological Sciences Division. I asked whether we might want to change the composition of the medal committees to get more female awardees (the recent awardees in hydrology are displayed here for the Henry Darcy Medal and here for the John Dalton Medal). The question…

Is a lack of competition affecting innovation in operational river forecasting?

Is a lack of competition affecting innovation in operational river forecasting?

Contributed by Tom Pagano, a HEPEX guest columnist for 2014 The opinions expressed here are solely the author’s and do not express the views or opinions of his employer or the Australian Government. I (with my co-authors) recently submitted a paper on the “Challenges of Operational River Forecasting”, which discussed institutional conservatism as a result of perceived liability associated with public forecasts. The paper postulated that if forecasters are concerned about liability, they will favor standard operating procedures over innovative – but…

Where do babies come from?

Where do babies come from?

Contributed by Maria-Helena Ramos and Florian Pappenberger In hydrology, many operational forecasters are usually receiving weather forecasters from a meteorological service without in-depth explanations regarding where these forecasts come from (there are a few laudable exceptions usually in organisations where the hydrological and weather forecast are issued by the same institution or where a concept of Public Weather Advisors exists – see for instance in UK). We can imagine that weather forecasters are so used to their forecasting practices that…

First step towards a multi-model probabilistic flood forecasting system for Europe

First step towards a multi-model probabilistic flood forecasting system for Europe

Contributed by Anna Kauffeldt, Fredrik Wetterhall, Florian Pappenberger The European Flood Awareness System (EFAS) provides flood information to national authorities around Europe. Warnings are based on a fully operational probabilistic forecasting system which addresses uncertainties in weather forecasts by using multiple weather forecasts (deterministic and ensembles) from several centres. These forecasts are used to force a hydrological model (LISFLOOD) and discharge predictions are compared to return flows determined from long-terms runs with observed data to issue alerts if certain threshold…

The Impact of using Ensemble Generator Produced Precipitation Estimates on the Calibration of a Hydrological Model

The Impact of using Ensemble Generator Produced Precipitation Estimates on the Calibration of a Hydrological Model

Contributed by Christopher J. Skinner The HEPEX Testbed Ensemble Representation of Rainfall Observation and Analysis Uncertainty was introduced in a previous blog post by Tim Bellerby. It aims to address some of the issues with representing uncertainty in precipitation observations by making use of ensemble simulation approaches and in the last few years I have been developing my research relevant to this Testbed, working with satellite rainfall estimates as one of Tim’s doctoral candidates. The doctoral research I undertook used…
