2020 Hydrology Days Special Issue of Colorado Water Published!

Each year the American Geophysical Union Hydrology Days meeting brings together water scientists, researchers and students to discuss the current state of the science and latest water-related research findings.  Due to the novel coronavirus (COVID-19) pandemic the 40th Annual American Geophysical Union Hydrology Days in-person meeting was canceled to protect public health and subsequently moved to voluntary online presentations to provide an opportunity for students and scientists to share their research. 

The organizing committee remains committed to sharing knowledge and ideas throughout our strong and vibrant scientific community. Therefore, a Special Hydrology Days Issue of Colorado Water was published in recognition of the hard work and outstanding efforts of our community. Colorado Water is a publication of the Colorado Water Center. The newsletter is devoted to highlighting water research and activities at CSU and throughout Colorado.

The two-day online conference was attended by 179 participants from over 33 organizations, including 10 academic institutions, two international institutions, five federal agencies, five local governmental agencies, four non-profits organizations, and several private/consulting firms. The program offered 21 webinar presentations covering interdisciplinary topics, including 14 student presentations. Conference proceedings for the webinar and presentation recording have also been published.

Keynote Speakers

Each year at the American Geophysical Union Hydrology Days meeting the Hydrology Days Award is presented in recognition of outstanding and significant contributions to hydrologic science.  We also honor two Borland lectures, one in hydrology and the other in hydraulics.  In partnership with the Colorado Water Center, the Dr. Norm Evans Lecture & Reception will also take place during the event.  We are excited to announce the Hydrology Days keynote speakers!

In Memory: Jorge Alberto Ramírez

Our esteemed colleague and dear friend Dr. Jorge Alberto Ramírez, professor of Civil Engineering at Colorado State University, passed away on March 28, 2020 in Fort Collins, surrounded by family. He was 65 years old. The full obituary is available here.

For nearly 20-years Dr. Ramirez served as the organizer of the internationally recognized, annual Hydrology Days Conference which brings world renowned experts to the CSU campus each spring semester. He took on Hydrology Days and raised the bar to serve students and university engagement clients at a higher level.

Over nearly three decades of service to Colorado State University, Dr. Ramirez led numerous research, education and training efforts to establish CSU as a leader in water science and technology.  His academic scholarship substantially expanded the University’s research reputation in the fields of hydrology, hydrometeorology, and water resources planning and management, benefiting not only CSU students and his fellow faculty members, but the profession as a whole.

Ramirez Hydrology Scholarship

Jorge will be deeply missed but lives on forever in our hearts and minds.  A memorial scholarship for Dr. Ramirez is being created for Civil and Environmental Engineering graduate students at Colorado State University.  Additional information is available here:

The Annual American Geophysical Union Hydrology Days meeting provides a unique opportunity for students, faculty, staff and practitioners to engage in wide range of water-related interdisciplinary research topics. The spring meeting promises to expand our attendance beyond engineering and hydrology by engaging colleges across campus to holistically represent the far-reaching facets of water.  The organizing committee includes representatives from the Colleges of Engineering, Natural Resources, Agricultural Science, Liberal Arts, History and, the School of Global Environmental Sustainability (SoGES) as well as the USDA Agricultural Research Service.

We recently turned the spotlight on students across campus to broaden our understanding of the interconnections of water and linked systems.  The Student Showcase provides an avenue for students to exchange ideas, present their research findings and refine their science communication skills.  This year we are excited to announce the Student Showcase will feature a Three Minute Thesis (3MT) & Poster Competition! The top scoring competitors will receive cash awards and select students will be invited to contribute to a special issue of Colorado Water! Students interested in entering the student competition must adhere to posted deadlines, register and submit an abstract to confirm their participation. 

Faculty, staff, practitioners and industry representatives are encouraged to attend the event and learn just how poised our students are to enter the workforce – take this opportunity to enhance the student experience and invest in the future!  Any attendee sponsoring student registration will receive a discount.  Learn more about this exciting opportunity by visiting the registration page.
