Fort Collins, Colorado


Keynote Speakers (2023)

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. We are excited to announce the Hydrology Days keynote speakers!

2021 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 2021 Annual American Geophysical Union Hydrology Days in-person meeting was hosted online 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 210 participants from nearly 75 organizations, including 21 national academic institutions, 28 international institutions, 15 private/consulting firms, seven federal agencies, and two non-profit organizations. The program offered 50 webinar presentations covering a range interdisciplinary topics delivered by eight undergraduates, 20 Masters degree students and 22 Doctoral students. Conference proceedings for the event have also been published.

The Annual American Geophysical Union (AGU) Hydrology Days meeting provides a unique opportunity for students, faculty, and practitioners to engage in a wide range of water-related interdisciplinary research topics. This event is hosted by the Civil and Environmental Engineering Department and One Water Solutions Institute at Colorado State University with support from the Colorado Water Center, USDA Agricultural Research Services, and University colleagues from the departments of Environmental Science and Sustainability, Geosciences, History, Soil and Crop Sciences, Agricultural and Resource Economics, Political Science and the Center for Environmental Justice.

The 2023 event lands on the United Nations’ annual World Water Day (March 22) with an emphasis on accelerating change to solve the water and sanitation crisis.  In addition, building upon the University’s Courageous Strategic Transformation we endeavor to broaden participation across campus as well as regional institutions. This year we encourage presentations from a wide variety of sessions designed to highlight the interconnections of water and linked systems. The Student Showcase will provide an opportunity for students to exchange ideas, present their research findings and refine their science communication skills.  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!  The spring meeting endeavors to expand our attendance beyond engineering and hydrology by engaging colleges across campus to holistically represent the far-reaching facets of water.
