About Hydrology Days

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 Department of Civil and Environmental Engineering and the One Water Solutions Institute at Colorado State University.

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. 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.
