Letter from the Executive Director 


Dear Friends of Water Science,

“Many researchers were not compliant with their published data sharing statement.” This is the headline of an article published in the Journal of Clinical Epidemiology in May. 

Quoting from the article: “Of 3,556 analyzed articles, 3,416 contained the DAS (data availability statement). The most frequent DAS category (42%) indicated that the data sets are available on reasonable request. Among 1,792 manuscripts in which the DAS indicated that authors are willing to share their data, 1,669 (93%) authors either did not respond or declined to share their data with us. Among 254 (14%) of 1792 authors who responded to our query for data sharing, only 123 (6.8%) provided the requested data.” Granted, this study is from the health sciences, but is there any reason to believe that the geosciences are different? In fact, the surest way to ensure data availability is to make the data publicly accessible and citable in a secure data repository, like CUAHSI’s HydroShare or Hydrologic Information System. 

Quoting from another article from closer to our science domain: “Data, which should be regarded as first-class outputs of science, are not routinely published as the necessary evidence for the knowledge claims based upon them. Without routine access to the vast and varied data streams of the modern digital world in an interoperable form, science will fail to respond to the complexity that is inherent in key modern concerns including the imminent environmental, social and economic crises humanity faces.”

Cudennec, et al., offer some lessons learned from the scientific community’s response to the global health crisis that might be applied to the water domain. They note that the possibilities associated with open science were demonstrated by those who by-passed traditional systems to share data and findings in non-conventional ways to more quickly respond to the pandemic. Creative approaches will be needed to continue to ensure access to data, as well as methodological and computational reproducibility. 

Nevertheless the community’s growing acceptance of and support for open science is encouraging, as we seek ways to support this goal. 

Take care, Jerad


Voices From The Community 

Hydrologist at Cloud to Street
Theme leader of the 2021 & 2022 Summer Institute

The CUAHSI Summer Institute (SI) wrapped up last month with a bang, and in doing so, set the stage for a new era for community participation with the U.S. National Water Center (NWC). This year’s SI included six research groups working on coastal flood inundation, machine learning, data assimilation and standardizing model selection, focused on the Next Generation Water Resources Modeling Framework (Nextgen; Ogden et al., 2021; CUAHSI Town Hall 2022). One of the core tenets of Nextgen is the need to have a fairly straight-forward path for contributions directly from the hydrologic research community, and this year’s SI was the first full-scale test of that path from research to contribution. There were several minor, and a few major, hiccups along the way, but from my perspective, the SI research was a successful demonstration of that tenet. Each of the SI research projects will be informative and potentially directly applicable to Nextgen.
Trying hard not to overstate this: The success of this year’s SI is several years in the making spanning the legacy of the extremely talented SI student fellows, the NWC’s hard working staff, the vision of the NWC leadership and the hydrologic research community in general. In a world that desperately needs serious advancement in hydrologic science, this year’s SI was a welcomed demonstration of progress, and I am proud to have been involved.I also look forward to the progress the hydrologic sciences community will make with Nextgen, as a community accessible model, for tasks ranging from hypothesis testing to multi-decadal continental scale water predictions. I believe this framework gives us the opportunity to come together and do hydrologic science in a much more collaborative and rigorous way.
I’ve spent the last decade building a career in water resources science and engineering. My experience spans non-profit, government, academic, consulting and technology sectors. The opportunity to be involved in the SI for the past two years has been a career highlight. While my interest in the dynamic and exciting problems we face in this industry has never waned, my enthusiasm in the community has never been greater.

General Announcements

CUAHSI wants to hear about your open source tool for water science! CUAHSI is interested in highlighting the work of water scientists who are creating open source tools for FAIR science, by facilitating an opportunity for creators to speak about their work through a lightning talk style webinar. If you would like an opportunity to speak about your open source tool, reach out to to speak about whether this opportunity would fit your needs and align with the theme. 

The 2022 CUAHSI Summer Institute concluded on July 28 with a Capstone event at the University of Alabama. The Capstone was well attended with over 150 people participating, both virtual and in person. A total of 22 students worked on 6 projects that were presented during the Capstone. Many of the students' advisors from their respective home institutions were physically present, as well as individuals from NOAA, the National Water Center, and the University of Alabama. 

Students are continuing to work to turn their final reports from the Summer Institute into publishable journal articles. A gathering of past Summer Institute participants is being planned for the Fall AGU meeting - stay tuned for more details. 

Congratulations to the 2022 Summer Institute Fellows for successfully completing the program!

Do you have a new water data science tool or have you discovered a data science application that is particularly helpful? Get the word out!

The CUASHI website is accepting blog posts that introduce new and review existing data science tools. These blog contributions are part of a new initiative by CUASHI’s Standing Committee on informatics designed to disseminate information about available tools, techniques and other data science resource used in hydrology and related disciplines. With rapidly evolving data science, it is often challenging for hydrologists and other water scientists to find or even be aware of new tools or how to choose the best tool for the job. We want to access the rich experience that CUASHI members have with using and often creating these data science tools.  Tools can include software, models, datasets as well as updates to existing tools. If you have built a new tool or have tools that you’d like to recommend, please consider contributing a blog post. To contribute, email

The difficulties of translating the results of research into a form that can be understood, shared, and used by researchers are well known to the water science and engineering communities.  When it comes to the results of hydroinformatics research, the tasks are no easier.  Research designs seldom communicate with end users and rarely take into account how findings and tools might best be used and by whom.  Consequently, results may never find their way into communities, either because of their technical features or because they never reach the people who need them the most. The purpose of the CUAHSI Informatics blog is to take on these challenges and serve as the bridge between the researchers and the community who might benefit from their results and tools. The tools that are described in the CUAHSI Informatics blog are contributing a set of workable, extendable, and flexible informatics strategies, many of which can be adopted, adapted, and ideally, scaled for use in water science and engineering research and education activities. While these tools and approaches hold great promise to improve the transparency of research and accelerate the diffusion of innovation in water resources research, doing so will require continued support from the community to achieve a culture shift towards collaborative, open-source, and reproducible workflow development. We are excited to learn more about your tools and datasets and have your thoughts and insights on the repositories of other tools. Let's explore the capabilities of informatics and analytics tools in water resources!

HydroShare’s growing use by the international water community is highlighted by one of this month’s most viewed resources: High temporal resolution hydrometeorological data collected in the tropical Cordillera Blanca, Peru (2004-2020).  The data were collected to evaluate how glacier mass loss impacted stream hydrology, and data have been downloaded 85 times. In fact, there are 23 datasets associated with Peruvian hydrology in HydroShare, offering  rich opportunities for hydrologic investigation.
