The 2020 meeting has been canceled due to concerns for public health and safety in regards to the current COVID-19 pandemic.


We remain committed to sharing knowledge and ideas throughout our strong and vibrant scientific community. We will make arrangements for students or scientists who remain interested in presenting their research via web-conference.

Anyone interested in presenting online (via webinar) should contact the Hydrology Days Organizing Committee by March 26, 2020 – please include your presentation title (hydrologydays@engr.colostate.edu).

In addition, we will publish limited online proceedings for all abstracts and manuscripts submitted to the 2020 meeting.


All presentations (including posters) are to be accompanied by an abstract for publication in the conference proceedings. The format should follow the template and instructions here:



Abstracts are required for poster presentations. Please be sure to indicate your preference for poster presentation during online registration. We will provide pins and other supplies to mount your posters.

Dimensions – HDs posters are expected to follow the following dimensions: 45″(w) x 36″ (h). We will supply poster boards which will have TWO posters placed side-by-side on each board so please adhere to the posted dimensions to ensure everyone has adequate space to share their work. In addition to the poster board, there will be a table on which you can place handouts or other information for interested people. 

* Final acceptance in scientific program is contingent on receipt of formatted abstract/manuscript by the posted deadline AND completed conference registration
