CUAHSI
recently hosted its Biennial Colloquium at the National Conservation Training Center in Shepherdstown, West Virginia. This year’s symposium focused around
the theme of “Finding your place in big data: using observations to understand
hydrologic processes for predicting a changing world.” More on that in a
moment, but first: CUAHSI.
What is CUAHSI?
CUAHSI
stands for Consortium of Universities for the Advancement of Hydrologic Sciences,
Inc. CUAHSI is funded by NSF, governed by a community of expert water resource scientists
and researchers, and serves as a collective voice for over 100 universities and
organizations on subjects related to water science. Generally speaking, CUAHSI aims to support the advancement of water science in the United States. This goal is operationalized
through workshops, conferences, the coordination of initiatives that assist
water researchers (i.e., HydroClient and Hydroshare, which simplify data
download and sharing), and more.
CUAHSI’s Biennial
Colloquium
The
Biennial Colloquium aims to host an event with content that lands between
“super specialized and only for a select group of experts” and “broadly
appealing to all environmental/biosystems scientists and engineers.” This
year’s program addressed all things “big data” within the context of water
science – big compute, large-scale modeling, tools and sensors that collect
loads of data, and case studies of big data analyses – by including a variety
of talks by distinguished lecturers, concurrent sessions on specialized topics,
workshops, water-related field trips, and a poster symposium.

Rather
than detail all of the interesting experiences had over the few days of the
colloquium, I’ll focus on two workshops that I participated in: (1)
Do-It-Yourself, Open-Source Wireless Environmental Data Logging, and (2) CUAHSI
Data-Driven Education.
EnviroDIY Mayfly: fun,
open-source, inexpensive, wireless environmental monitoring
At the “Do-It-Yourself,
Open-Source Wireless Environmental Data Logging” workshop, my geekiness reigned as I tinkered with the Arduino-based
EnviroDIY Mayfly data logger. The workshop was directed by the brains behind
the Mayfly, Steve Hicks (Research Engineer) and Dr. Anthony
Aufdenkampe (Associate Research Scientist) of the
Stroud Water Research Center. The Mayfly was born from the desire to create an
extensive network of sensors that monitored various environmental variables,
but on a tight budget. The EnviroDIY Mayfly logger board is based on Arduino, an
open-source platform that uses simple and user-friendly hardware and software
to translate inputs (i.e., a digital signal, button push, sensor trigger, or even
a Twitter message!) into useful information based on user-programmed
instructions.

At first glance, the Mayfly looks like a
simple circuit board with a few additional components. These components include
an atomic clock, microSD memory card slot, several input pins (i.e., 8-bit
Analog-to-Digital, 16-bit ADC), microUSB port, Bee socket (allows for wireless
capability), and solar panel connector. For a full list of Mayfly features,
check out their website. All of these components allow for data to be collected
from several solar- or battery-powered sensors, and logged on the microSD card that
the user has plugged into the Mayfly. Users program the Mayfly using
open-source software that is both Mac OS X and Windows compatible. The code is
easy to write, and the creators of the Mayfly have created an online community
called EnviroDIY that includes blog posts and forums on all
things open-source + environmental monitoring. On this website, Mayfly users
can download and contribute other open-source codes, making this technology
very accessible for those of us who lack experience in Arduino. Have I convinced you that it’s awesome yet?
If not, maybe the price will: you can buy a complete EnviroDIY Mayfly loggerstarter kit on Amazon for $90.

Teaching Hydrology with Data
The second workshop I
attended focused on Data and Model Driven Hydrology Education. Participants were asked to create a
data-driven hydrology assignment prior to attending the workshop. These
assignments were then contributed to the Science Education Resource Center (SERC),
which is a NSF-funded venture with the mission of improving "education in the Earth sciences and beyond." The SERC website includes several different modules
with user-contributed earth science assignments that target K12 through higher education students,
making this online platform a wonderful resource for any and all educators
working in natural sciences and engineering. If you ever find yourself needing
to create an educational exercise, save yourself some time and check out the
brilliant assignments on SERC!

All in all, I found that the
CUAHSI Biennial Colloquium provided several unique learning experiences, and
opportunities for interactions with leaders in the field of hydrology. Whether
you’re a student like me, or an experienced water professional, you should
strongly consider venturing to the wilds of West Virginia to participate in
this conference in 2018! If you don’t want to wait that long, there will also
be a Hydroinformatics conference coming up in July of 2017 in Logan, UT. Hope
to see you there!
