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. Digital copies of the meetings from 2000-2018 found here. Digital copies of the meetings from 2019- are published in Colorado Water Center newsletters issues.
