Tentative Agenda of US-Japan Joint Seminar on
the Hydrology and Biogeochemistry of Forested
Catchments
Imin Conference Center, East-West Center,
University of Hawaii
Preamble: Catchment hydrology has evolved quite differently in the US and Japan.
Much of catchment research in the US is motivated by interest in explaining stream
water chemistry. Catchment hydrology in Japan is grounded more in soil physics with
geotechnical origins. As a result, the strengths of the two countries
differ—interdisciplinary approaches are common in the US but rare in Japan. On the
other hand, Japanese hydrologists have very sophisticated and novel hillslope and
catchment monitoring approaches and process interpretations. To date, there has been
little interaction between catchment hydrologists in the two countries.
The objective of the US-Japan Joint Seminar is to examine the cultural differences in
catchment hydrology research and to highlight some of the cutting edge studies from
both countries. The workshop component of the meeting is designed to facilitate
informal exchange of ideas and approaches to educate each side on what the other is
doing. We hope that a consensus will emerge from these discussions that provides for a
robust quantitative description of hydrological flowpaths that control biogeochemistry
at the catchment scale in forested systems.

How do we translate knowledge and models of what occurs at the profile and
hillslope scale to larger scales?
Are hillslope chemical signatures "re-set" in the near-stream zone? To what
extent should we focus on hillslope or near-stream processes to explain
geochemical flux into receiving waters?
Representative elementary areas: fact or fiction - what does the field evidence
say?
What are the averaging lengths in catchments in terms of flowpaths?
Are there any best ways to integrate methods for more well understanding

General Information on the East-West Center and
Accommodation
The East-West Center, primarily known for its role in promoting understanding among
the nations of Asia, the Pacific and the United States since its establishment in 1960,
9
also welcomes conferences, meetings and workshops by other organizations.
The Center's 21-acre campus is ideally situated in a lush, quiet area adjacent to the
University of Hawaii's Manoa campus. It is convenient to all of Honolulu's resources,
yet feels a world away from the bustle of Waikiki and downtown.
The Hawaii Imin International Conference Center is designed for an international
audience, offering outstanding resources to produce successful events of all kinds. And,
because the East-West Center is a non-profit education and research institution, the
Center can make its facilities available at a reasonable cost.
With 11 meeting rooms, a large auditorium and other meeting places, including lounges,
a business center and outdoor area, the Center offers more than 20,000 sq. ft. of
conference space to accommodate groups requiring conference, reception, banquet and
workshop facilities.
The Garden level, designed to accommodate receptions and luncheons, overlooks a
tranquil Japanese Garden. Located on the ground floor of the Imin Conference Center,
the Garden level can be divided into smaller rooms or opened up to all 4968 sq. ft.
Housing:
Lincoln Hall is a four-story building serviced by one elevator. Lincoln Hall houses
visiting scholars and short-term conference participants. All apartments have cable TV,
telephone service and private bathroom/toilet facilities. A limited number of apartments
with kitchens are also available.
Each residence hall has a reception desk to provide check-in and check-out services.
The desks also take messages, provide change for laundry and vending machines, issue
spare keys, and provide general information.
