Submit a Session Proposal before March 15th for CUAHSI's Conference on Hydroinformatics!
Dear Friends & Colleagues, 

Sunny spring weather is right around the corner, and CUAHSI is here to brighten your day with this month's news!

In this edition, you can expect to learn more about CUAHSI's Spring Cyberseminar Series, this year's Conference on Hydroinformatics including the calls for session proposals and abstracts, HydroShare updates, and more! 

Don't forget to check out our training and workshop schedule. We still have spots open for some, and you don't want to miss out! We are also announcing the deadline for CUAHSI's Instrumentation Discovery Travel Grant! Keep reading to find out more. 

Lastly, CUAHSI had some international visitors this week! Read more about their endeavors below. 



Dear Friends of Water Science:

CUAHSI had some visitors this week. We were pleased to host guests from Vietnam in our offices on March 11 – 13. Guests included:
  • Dung Kieu Tuan, Lecturer in Computer Science and Engineering from Thuyloi University. Thuyloi University focuses on all aspects of water resources, and has four campuses, including the main campus in Hanoi; 
  • Tung Nguyen Thanh, Dean of Computer Science and Engineering, Thuyloi University;
  • Chi Ngoc Le, Machine Learning and Graph Theory Team leader, School of Applied Mathematics and Informatics, Hanoi University of Science and Technology; and
  • Tho Nguyen, Senior Scientist at University of Virginia.
The group focused on potential applications of CUAHSI’s water data services, especially HydroShare, for data management in the Mekong River basin through the Lower Mekong Initiative. Miguel Leon, University of Pennsylvania, also participated in part of the meeting to discuss the ODM2-Admin package as a solution for sensor data management that links to HydroShare. In early April, I will be speaking at a State Department bi-lateral workshop on data management solutions in the Mekong River basin, and I will travel to Laos in May to work with the U.S. embassy and the Mekong River Commission to encourage water data sharing in the region. We are pleased to be able to work with multiple partners on water data collection and management in this important region.

I also participated in an International Association of Hydrological Sciences conference on Measurements and Observations in the 21st century (MOXXI), co-hosted by CUAHSI. About 90 percent of the participants were from outside the U.S., and it was fascinating to learn about the innovative solutions being developed. Many groups are developing their own inexpensive, specialized sensors using off-the-shelf materials. In addition, at one level of sophistication, an app for measuring stream discharge using an Android-powered smartphone was demonstrated, but there also were discussions about engaging citizen scientists in water data collection.

These engagements are helping CUAHSI to expand the hydrologic sciences community and bringing CUAHSI tools to new users.

All the best,

CUAHSI's Data Down-low

Delaware River Watershed Initiative
Check out data from the Delaware River Watershed Initiative on HydroClient!
The Delaware River Watershed Initiative is an ambitious effort underway to protect and restore the Delaware River Basin’s water quality and overall ecological health. Kick-started by a $35 million commitment by the William Penn Foundation, the Delaware River Watershed Initiative (DRWI) is targeting eight “clusters” within the basin for conservation investment. More than 50 leading nonprofits have joined together, aligning priorities for land protection and restoration projects and assessing water quality impacts using standardized methods. Clusters were delineated using landscape variables including land use, conservation easements, and land trust areas in addition to input from local nonprofits. Monitoring sites in each cluster were chosen based on how representative of the cluster’s landscape they were. These sites represent the “typical” conditions of each cluster. The diversity of the landscape in each cluster influenced the number of sites, and they represent a range of watershed sizes (9-313 km2). Monitoring for the DRWI began in 2013 and will continue through at least 2020. Chemical, algae, fish, and macroinvertebrate data are collected at each of the sites.

Submit a Proposal for CUAHSI's Instrumentation Discovery Travel Grant!
CUAHSI is pleased to announce the addition of a Hydrologic Instrumentation Facilities page to the website. This page contains information about observatories and facilities available to the community for training and conducting hydrologic research. It may also be especially useful to our Instrumentation Discovery Travel Grant (IDTG) applicants who want to learn the details of hydrologic instrument installation, operation, maintenance, and data processing by visiting experts or scheduling reverse site visits. In 2019, CUAHSI will offer only one proposal deadline for the IDTG program, April 19, which is a change from previous years when there was both a Spring and Fall deadline. If you are a graduate student or early career researcher, we hope you will consider submitting a proposal this Spring!

Meet the CUAHSI Community

This is the next installment of our series as we shine the spotlight on a member of the CUAHSI community.

[Know a CUAHSI member that deserves to be highlighted? Contact with a nomination!]
This month’s Meet the CUAHSI Community introduces you to Margaret Zimmer. Margaret is an avid HydroShare user, and an assistant Professor in the Fresh Water Earth and Planetary Sciences Department at the University of California, Santa Cruz.

What are your research interests?
The central research goal of my lab is to understand how and why precipitation inputs are partitioned into watershed outputs, namely streamflow, deep aquifer recharge, and evapotranspiration. We are further interested in the biogeochemical implications as well as how humans influence this hydrologic partitioning.
How has HydroShare impacted your research? 
CUAHSI’s HydroShare is a unique community resource that allows for the storage, sharing, and discovery of hydrologic datasets, code, and other resources. Not only does HydroShare allow members of my lab the opportunity to safely store and share our results, but it allows us to identify data and other studies that are complimentary to our research. HydroShare has provided a bridge between our efforts and our community’s work, which undoubtedly strengthens the research products and results we produce.

Why should others use HydroShare?  
The long term success of CUAHSI’s HydroShare is contingent on our community’s use of this resource. HydroShare provides an incredible and unprecedented resource to our community and is arguably underutilized. HydroShare is also versatile and can serve several purposes, depending on the needs of the user, thus I encourage researchers to explore its capabilities!

How would you describe CUAHSI? 
CUAHSI serves several roles to me and my lab and thus can be described in many ways. CUAHSI provides our community with workshops, conferences, tools, and databases that ensures the transfer of knowledge to anyone interested. CUAHSI also serves as a community hub and provides opportunities for networking and sharing of ideas. Finally, CUAHSI serves as a support system – I personally have approached CUAHSI’s staff via email or in person about problems I am having in my research and have received invaluable and unprecedented support. This is a unique and important aspect of CUAHSI, especially for early career researchers.

What has been your proudest professional accomplishment to date? 
As an assistant professor, I have the opportunity to mentor students as they grow as scientists. I have found pride in watching the development of the undergraduate and graduate researchers in my lab and I have felt a great sense of professional accomplishment as my students succeed in their individual endeavors.

What are some of your favorite hobbies outside of work? 
While I greatly enjoy exploring the coasts, mountains, and redwood forests of Santa Cruz (where I live), I absolutely love to garden, read, and relax in my own backyard.
