Our process understanding and ability to quantitatively predict water fluxes away from boundaries is generally better than at the interfaces of these boundaries, where the characteristic physical processes change and parameterizations are required to express their coupling. But it is often the interfaces that we are most interested in, and in many cases that define, hydrologic fluxes.

We are using this challenge of understanding water across interfaces as an organizing principle for the CUAHSI 2010 Biennial Meeting. Theory, observations, and modeling are of interest as cross-cutting approaches that can be used to address this theme.

The format of this meeting is invited 30-minute talks, plus a poster session of contributed papers. Ample time is provided for discussion and interaction. One and a half days are reserved for workshops and an update on CUAHSI community activities. Visit the Sessions schedule page.

Complete Workshops Schedule

There are a few events at the upcoming colloquium that are being offered specifically for graduate students. Events will include:

1. Reception and graduate student networking on Sunday, July 18th. Business to include organizing a graduate student committee within CUAHSI.
2. Special session by Jeff McDonnell on writing research papers.
3. Tour of NCAR/UCAR Facilities, and meet-and-greet with NCAR/UCAR personel.
4. Poster sessions throughout the week (open to students and professionals) - abstracts due by May 31st.

Please circulate this among students at your institutions, and feel free to contact Adam Ward at asw178@psu.edu if you are interested in taking a leadership role within the CUAHSI graduate student group.

The CUAHSI Board of Directors is pleased to announce that travel grants of up to $500.00 are available to graduate students who present a poster at the upcoming Biennial Colloquium, to be held in Boulder, CO, July 19-21, 2010. The grants will be provided on a first-come, first-served basis. The grants will be a reimbursement for travel expenses rather than an outright payment. Applicants must submit the request for travel support to busmgr@cuahsi.org after submitting an abstract on the abstract submission page. Details on reimbursement for expenses will be provided to the applicants upon receipt of their travel support request email.

The deadline for submitting your poster abstract is May 31, 2010. The deadline for submitting your request for travel support is June 30, 2010.
