This first CUAHSI colloquium features an exciting line-up of sessions exploring cutting-edge issues in hydrologic science, biogeochemistry, and environmental engineering that can benefit from the community planning that CUAHSI has been leading. Session topics are drawn from the hydrologic synthesis projects currently underway and from observatory planning efforts, including the WATERS Test Beds, Critical Zone Observatories, and various state efforts. Each session will consist of 3 30-minute invited talks from leading scientists around the world to be followed by a moderated 30-minute discussion session. Contributed papers will be presented as posters that will be viewed immediately following the oral session.

Keynote speakers are Wilfried Brutsaert (Cornell University), who will present the Peter Eagleson Lecture on Hydrologic Science and Robert Hirsch (USGS), who will present the Reds Wolman Lecture on Humans and Water. We hope that both Pete and Reds will be able to join us to offer a few remarks.

In addition to these sessions, there will be a workshop on the use of CUAHSI’s Hydrologic Information System (HIS) Web services for data publication and retrieval. Come and learn how to use these services to access data from major agency databases, such as the USGS NWIS system and EPA’s STORET system, as well as academic research sites. Learn how you can contribute data from your field study to this system for community use and recognition through a citation system.

Following the Biennial Colloquium, there will be a hands-on Workshop on Wireless Autonomously Powered Environmental Sensing, offered by CUAHSI’s Hydrologic Measurement Facility. Separate registration is required and space is limited for this workshop, so act quickly!

The abstract deadline was May 31, 2008. Thanks to all who have contributed abstracts. We will publish a list of the poster titles prior to the meeting and will provide electronic copies of the abstracts for your continuing edification.

Mark your calendars and plan to join us in Boulder for this exciting colloquium and workshop. It will be a CUAHSIpalooza!
