STAHY 2019

by Svenja Fischer

The tenth edition of the STAHY International Workshop, STAHY 2019, is organized by the International Commission on Statistical Hydrology (ICSH) of the International Association of Hydrological Sciences (IAHS), in cooperation with the Hohai University. It will be held in Nanjing, China betweeb 19-20 October 2019 at the College of Hydrology and Water Resources, Hohai University. The potential participants could submit 1-page abstract through the IAHS-Copernicus Abstract Management System (will open soon).

STAHY 2019, similarly to previous editions (STAHY 2018 in Adelaide, South Australia & STAHY 2017 in Warsaw, Poland), will focus on statistical methods for hydrological applications. The topics range from big data to extremes and climate change but also prediction and uncertainty. This diversity makes this conference so interesting. I participated in this conference twice and I can highly recommend the participation.

Due to the small community with about 100 people, the conference is very familiar and one gets in touch with the other researchers easily. It has been a great opportunity for me as an early career scientist to talk to experts about my research. On the day before this workshop (Oct 18, 2019), also an Early Career Course will be held as well as a short reception for the early career members. Further information can be found at: http://www.stahy2019.org.

I hope to see many of you at the STAHY 2019!

Broader Impacts Can Bring Hydrological Processes to Life

A –Streams of Thought– contribution by  John Van Stan & Jan Friesen.

Writing my first full science proposal in a new tenure-track position was challenging but, honestly, most sections flowed smoothly from my fingertips. The motivation, background, research approach, hypotheses, methods, and even project and data management plans fit snuggly together beneath the overarching question: Will forests interact differently with rainfall along a natural-to-urban continuum? Then, confidently, I wrote “Broader Impacts” in bold, sipped my single-origin third-wave coffee, and stared blankly at the blinking text cursor. Every other blink interrupted my stream-of-thought until, after mere minutes, the cursor had elevated itself from nuisance to arch-nemesis. It became clear that each blink was a taunt as it shed its disguising vowel for a more rancorous one, becoming the villainous “Curser.” Unluckily, I knew this villain all too well. I also knew that I had to act fast, before the Curser’s mocking winks dissolved my thoughts to mush! With astonishing rapidity, my fingers fluttered out several sentences, forcing the Curser to retreat down the page. There it sat, one line below my newest paragraph, derisively staring at this anemic assembly of platitudinous promises. Like a bot trained by reading innumerable “Broader Impacts” sections, I had spewed out some vanilla text pudding that blandly promised to “present and publish findings,” “integrate work into my courses,” “extend current scientific theory,” and so on …list abbreviated as to not bore the reader any more than was necessary. I locked an unflinchingly open stare with the Curser’s unflinchingly blinking slash. It was clear: The battle for unique broader impacts had begun! Continue reading

YHS Collection on “Unexpected Results in Hydrology”

by Caitlyn A. Hall, Andrea Popp, Hannes Müller, and Tim van Emmerik

Understanding and learning from unexpected results is a fundamental element of science. Different names exist for these results, e.g., failures, obstacles, or unexpected results. Although all of these names sound unexpected, they are important for the understanding of processes, developing and testing of theories, and identifying pitfalls and possible dead-ends in science.

By carefully designing and conducting experiments with some level of trial-and-error, researchers eventually find results that will be published in peer-reviewed scientific journals. Paradoxically, we typically only publish the successful tests and their results. What comes of the weeks to months of critical information that led to this successful experiment? It usually remains in the dark. However, not sharing unsuccessful iterations or unexpected results — defined here as experiments that do not adequately confirm an accepted hypothesis, despite sound and careful experimental design, planning, and execution — along the way prevents others to learn from these endeavors (Nature Editorial, 2017).

In the past, many philosophers, including Popper (1963) and Chalmers (1973), have emphasized that science can only advance by learning from mistakes. Moreover, recent literature in various fields elaborate on the many benefits and values of publishing unexpected results and call upon the scientific community to nurture their dissemination (e.g., Andréassian, et al., 2010; Schooler, 2011; Matosin et al., 2014; Granqvist, 2015; Goodchild van Hinten, 2015; Boorman, et al., 2015; PLOS collections; 2015, 2017; Nature Editorial, 2017). Despite the various calls to report such results and the frequency they occur in the labspace, they are still underrepresented in most fields of our current publication system. The reasons can be manifold such as, a lack of incentive (no scientific reward) or the fear of a negative reputational impact.

So, why should you report your failed approaches and unexpected findings?

By reporting on unexpected findings, we can do the following:

  • Decrease the currently existing publication bias towards positive results
  • Save time and resources of other scientists exploring same/similar hypotheses and/or approaches
  • Increase transparency and reproducibility of our studies
  • Share all findings of publicly funded projects

How and where can you share your unexpected findings?

You can share your unexpected results at:

  • Special journal issues
  • Dedicated sessions at conferences
  • Platforms (e.g., Researchgate)
  • Supplementary material of your paper
  • Blog posts

We aim to stimulate this discussion via the new Young Hydrologic Society collection “Unexpected Results in Hydrology”. We want to instill a positive perception to change the way in which the scientific hydrologic community value unexpected and negative results including individual researchers, scientific societies, funding agencies, and publishers. Therefore, we invite researchers to report their negative and unexpected results, such that we are able to holistically advance science – by sharing our failures, not only our successes.

Reporting on such findings should include the following components in a maximum of 3,000 words: 1) an original research objective and expected results, 2) a brief summary of experimental design and methods, 3) discussion on the experimental results and challenges, including images and/or figures, and possibly 4) lessons learned and the path forward.

After a peer-review done by the editors of this collection, the post will get a DOI and will be visible on the YHS website and on a dedicated ResearchGate project site. On ResearchGate we invite discussions on published submissions such that the authors can receive feedback to facilitate new insights from the scientific community. Upon enhancing their previous analysis or coming to new conclusions, we welcome resubmissions by the original authors.

Call for Applicants — IAHS Early Career Committee

Early Career scientists make up a significant amount of our community, creating an opportunity to include a new generation of hydrologists as active contributors to IAHS. Early Career scientist involvement in geoscientific organizations has rapidly increased over recent years. Organizations such as the American Geophysical Union (AGU) and the European Geosciences Union (EGU) have adopted Early Career representation in committees, board and executive committees.

During its Bureau Meeting in July 2017 (held in Port Elizabeth, South Africa following the IAHS Scientific Assembly 2017), IAHS decided to strengthen its Early Career scientist representation to enable more active participation of those members within IAHS Commissions and Working Groups. To achieve this goal, in line with the proposal submitted by Tim van Emmerik and Nilay Dogulu—and approved by the Bureau members—IAHS will establish an Early Career Committee (ECC) consisting of the Early Career Representative of each IAHS Commission plus a chair and co-chair. The IAHS definition of Early Career embraces scientists up to 5 years after completion of the PhD (allowing for an extra year per child for parents if they took parental leave).

IAHS Early Career Committee (ECC) structure

The ECC is aimed at representing the Early Career membership of the IAHS at the highest level, and within each Commission. ECC members are dedicated to fostering dialogue between Early Career members, and between current and future generations of hydrologists. The ECC chair will be appointed by the IAHS Bureau and will join the IAHS Bureau meetings as an observer. The chair will be encouraged to also be an active member of the Young Hydrologic Society to assure strong connections with other Early Career initiatives in the hydrological community.

Towards Regional Information to Improve Our Understanding on Weather, Water, and Climate Extreme Events

A –Streams of Thought– contribution by  Caroline Aubry-Wake, Gaby Langendijk, Marisol Osman, Carla Gulizia.

On May 3-5, 40 early careers researchers from 23 different countries grouped together for an in-depth interdisciplinary discussion on generating regional information to improve our understanding of weather, water and climate extreme events. This workshop, organized jointly by the Young Earth System Scientist (YESS) and the Young Hydrologic Society (YHS), took place prior to the 2018 GEWEX Open Science Conference (OSC). The goal of the workshop was to develop a shared ECR vision on challenges and ways forward to enhance the generation of usable regional information for water, weather and climate extremes, and the utility of that information for users, decision makers and other stakeholders. During the three days, the discussions centered on three topics: data sources (conventional and unconventional), scale-interactions and user needs.

Hydroinformatics for hydrology: extreme value modelling

At the EGU General Assembly 2018 in Vienna, “Hydroinformatics for hydrology” short course (SC) was run for the fourth time. The previous themes of the SC were data-driven and hybrid techniques, data assimilation, and geostatistical modelling. And this year the focus was extreme value modelling. Participants of the SC were given a state-of-the-science overview of different aspects in extreme value analysis along with relevant case studies. Available R functions for extreme value analysis were also introduced. Thanks to Hugo’s excellent lecture, we now know common issues and pitfalls in using extreme value models (i.e. modelling choices and assumptions). We would like to thank Dr. Hugo Winter from EDF Energy for delivering the lecture. You can find his lecture slides (and exercises) here:

Research “Hylight”: Hydrological response characteristics of Mediterranean catchments at different time scales: a meta-analysis by Merheb et al.


Mohammad Merheb

In January 2016, Mohammad Merheb and colleagues published a paper on comparative Mediterranean hydrology in Hydrological Sciences Journal. At the 2017 IAHS General Assembly, Mohammad was awarded the Tison award for this paper, and we decided to ask him a couple of questions.

Q: Let’s start with the basics. Where are you from, where are you based, and what are you working on now?

A: I am from a small village called El-Bireh located in Akkar district in the northern part of Lebanon. Now, I live and work in Tripoli, a port city in northern Lebanon where I am based at the Lebanese University. However, I must say that the article that won the Tison award was written when I was doing my PhD. I was based in Irstea, Montpellier, France and the L-CNRS, Beirut, Lebanon.

Nowadays, my main work is teaching. Nevertheless, I am still working on some research projects that I have started during my PhD. These are mostly related to catchment classification and regionalization studies.

The role of Early Career Scientists in community research

Repost from HEPEX blog

Contributed by Florian Pappenberger and Maria-Helena Ramos (both considerably beyond the early career stages, they admit)

Science and forecasting practice are the foundations of the HEPEX community. These are certainly the routine of many of us during our office hours and while spending time in front of your computers.

But this community is also based on individuals, and this is often what really makes it fun to go to meetings, workshops and conferences. Face-to-face interactions often bring new ideas into form (see also this previous post from CSIRO team), while also helping us to further develop interpersonal skills.

Meet the Expert in Hydrology: Is research at different spatial scales connected?

A –Streams of Thought– contribution by  Wouter Knoben, Shaun Harrigan, David Wright, Wouter Berghuijs

Scaling (i.e. the transfer of knowledge across scales) and scale issues (i.e. the associated problems) are at the heart of most hydrologic puzzles. In the most recent “Meet the Expert in Hydrology” session, organized at the EGU General Assembly 2017 in Vienna, YHS invited three speakers to identify to what degree their research is connected, influenced by, and influencing research at other spatial scales. By evaluating the current state of research and discussing future directions we tried to shed some new light on the question “Is hydrological research at different spatial scales connected?”. This is what we learned…

Opinion papers in hydrology: Why and how? (short course) at EGU 2017


Opinion paper short course at EGU17

by Anna Solcerova (Delft University of Technology, convener)

Young (and mature) scientist visiting the EGU 2017 conference had a chance to participate on a short course titled “Opinion papers in hydrology: Why and how”. Bettina Schaefli, Vazken Andréassian, and Hubert Savenije shared their experience and opinions on this topic. Participants of this course could enjoy insights into pros and cons of opinion papers, as well as personal advice of the speakers. Bettina suggested to base an opinion on a quantifiable message, while Huub believes that opinion paper should be personal and controversial. Vazken discussed the use of humour in opinion papers and emphasised the readability. Two things all speakers agreed on was that one should write only few opinion papers, and that good opinion needs “time to settle in” (just like pancake batter).

Ralph Trancoso

A: I am from Brazil, and have moved to Brisbane in Australia, about four years ago, to undertake my PhD at the University of Queensland. Having finished PhD a couple of months ago, I am now working for the Queensland government. My current main research focus is catchment ecohydrology. By integrating hydrology, remote sensing and ecosystem sciences, I explore the spatio-temporal variability of catchments biophysical properties to generate new insights into their hydrological functioning and changes. I compare the water and energy exchanges of many catchments spanning large extents to investigate large-scale ecohydrological patterns. Continue reading

10 guidelines for an awesome poster

A –Streams of Thought– contribution by Andrea Popp.

A scientific poster is a visual communication tool summarizing your work and encouraging conversation with colleagues. However, posters are often poorly designed, e.g., they are densely packed and overloaded with text. This makes it difficult and tiring for the audience to understand the content. The following list provides 10 guidelines for an awesome poster to help you to communicate your work efficiently. We spiced this blog with insider tips from recent EGU and AGU Outstanding Student Poster Award winners (Skuyler Herzog, Ingo Heidbüchel, and Michael Stölzle).

Why every scientist should make a science video

A –Streams of Thought– contribution by Yvonne Smit. 

As a kid imagining a scientist, we always thought of a professor with messy grey hair, weird glasses, handling all sorts of flasks with chemicals in it (including an explosion once in a while). In our mind those chemicals were magic potions to make someone happy or (in case of the Evil Queen from Snow White) to kill somebody. Not exactly what a scientist is or does, right? Other type of scientists we could think of as a kid were the ones that invented stuff like robots, electric wings (that you could tie on your back and would make you fly), etc. The latter idea might be representing reality a tiny bit more, but most of the scientists are not like these nutty professors or dodgy inventors at all. Soon enough, you’d find out that you do not really know what it means to be a scientist, so why become one? What appeals more to the imagination are doctors, lawyers, teachers, and firemen. So my question nowadays is: how do we stimulate children to go into science? Or, formulated in a different way: how do we stimulate parents to motivate their children to go into science? Let us begin by communicating about the things we do as a scientist and create awareness! After all, we are all trying to make the earth a better place to live on. This can be done as a scientist or by anyone who is interested in science and would like to make his or her own contribution to the world. Therefore it is important to show how science is done, what its use is and how cool it can be. However, scientific articles might not be the most appealing way to deliver the message. Perhaps an informal blog or a short science video is more effective? Continue reading

Permafrost hydrology: the urgency for understanding in a thawing world

A –Streams of Thought– contribution by Matthew Morison.

A little background: recently, the Canadian branch of the Young Hydrologic Society was formally recognized as a committee of the Canadian Geophysical Union Hydrology Section. As an international member of the diverse global YHS community, we are so excited to be apart the next generation of hydrological research and to have new links to so many different regions and countries! In this spirit, this article strives to shed some light on some research which is not uniquely Canadian (in fact, far from it), but remains a large research focus in Canada – permafrost hydrology.
