Conference Scope This meeting will explore current multidisciplinary methodologies for assessing the impact of non-point source (NPS) pollutants upon soil and groundwater resources at field, basin, regional, national, and global scales. The meeting will encourage interaction between the disciplines of spatial statistics/geostatistics, remote sensing, geographic information systems (GIS) and solute transport modeling to enhance the development of techniques for the measurement, assessment, and modeling of NPS pollutants in the vadose zone and in subsurface waters.

Topics to be Discussed


Conference Dedication The 1997 Joint American Geophysical Union Chapman - Soil Science Society of America Outreach Conference is dedicated to the memory of Professor Robert J. "Jeff" Wagenet from Cornell University. Jeff was both a gentleman and an international scholar whose work in the area of modeling nonpoint source pollutants was of the highest caliber. Jeff's integrity, self-effacing manner, positive and generous attitude, grace and dignity set an example for all to emulate. Jeff's contributions to Soil Science are appreciated and his presence will be deeply missed by his many students and colleagues.

Goals and Objectives As the world's population continues to grow, the foremost nonparochial problem facing man is meeting the world's food demand with a sustainable agriculture. Sustainable agriculture strives to optimize food production while maintaining economic stability and minimizing impacts upon the environment and minimizing the utilization of finite natural resources. Assessing the environmental impact of non-point source (NPS) pollutants at local, regional and global scales is a key component to achieving sustainability of agriculture. Because of the volume of data, the spatial heterogeneity of the earth's surface and subsurface, and the complexity of solute transport processes, a multidisciplinary approach is required to assess the impacts of non-point source pollutants upon soil and groundwater resources.

The subdiscipline of spatial statististics is essential to establish the uncertainty of spatial information and to characterize the spatial variability; remote sensing is needed to measure/estimate physical, chemical and biological properties and to measure/estimate real-time environmental impacts over vast areas in a cost effective and timely manner; geographic information systems (GIS) are needed to manipulate, store, retrieve and display the tremendous volumes of spatial data; and solute transport models are needed to simulate future scenarios to assess temporal and spatial changes.

The objective of this jointly-sponsored conference is to explore current multidisciplinary methodologies for assessing the impact of non-point source pollutants upon soil and groundwater resources. Topics covered by the conference will include, but are not limited to, spatial analysis, geostatistics, remote sensing and non-invasive techniques for solute transport parameter measurement, solute transport parameter estimation techniques (e.g., pedo-transfer functions), scaling, uncertainty and sensitivity analysis, fuzzy set theory and fractal approaches, risk assessment, GIS and solute transport modeling as related to the assessment of the impact of non-point source pollutants upon soil and groundwater resources from a local to a global scale. The goal is to stimulate interaction between the disciplines of spatial statistics/geostatistics, remote sensing, GIS and solute transport modeling to enhance the development of techniques for the measurement, assessment and modeling of non-point source pollutants in the vadose zone and in subsurface waters.

Conference Location The conference will be located at the Mission Inn in Riverside, California. The Mission Inn is a registered state historical monument which has recently been totally remodeled.

The Mission Inn offers a unique Spanish mission setting in a tranquil, luxurious environment. As a state historical monument, the Mission Inn has in the past provided lodging to several U.S. Presidents and other dignitaries.

The Mission Inn is an ideal conference location:

Anticipated Participants The conference is open to all scientific disciplines and intended for GIS specialists, geographers, remote sensing specialists, spatial statisticians, geostatisticians, time-series analysts, solute transport modelers (including soil physicists, soil chemists, agronomists, civil engineers, wastewater specialists, and hydrogeologists), hydrologists (surface and subsurface), environmental scientists, geomorphologists, groundwater specialists, water resource specialists, water conservationists, cooperative ag-extension specialists, risk assessment specialists, toxicologists, and natural resource policy-makers.

Presentations Oral Presentations:
Keynote presentations are 45 minutes in length (5-10 minutes for Q&A); invited presentations are 30 minutes in length (5 minutes for Q&A); and contributed presentations are 15 minutes in length (2-5 minutes for Q&A). Oral presenters should check the Conference Program for exact time schedule and length of their presentation. Oral sessions will be located in the Music Room.

All oral presenters are required to submit a short biographical sketch (one paragraph) to AGU for introduction purposes by September 15.

Oral Session Chairpersons:
All keynote and some selected invited speakers are asked to serve as Session Chairpersons. Each Session Chairperson will be responsible for (a) introducing each presenter within their session using the bio provided by the presenting author, (b) directing the Q&A at the end of each presentation, (c) making certain that each presentation oes not exceed its allotted time, and (d) preparing a 1-2 page summary of the session, which should include a brief summary of each presentation and an overall summary/conclusion for the session.

Audio Visual Equipment:
The standard audio visual equipment for oral sessions is one slide projector, one overhead projector, and two screens. If you require additional audio visual equipment, please contact Brenda Glenn for more information.

Poster Presentations/Computer Demos:
Poster presentations are scheduled for 7:00 P.M.-9:30 P.M. on Tuesday, October 21. Poster presenters will be required to set up their posters between 6:30 P.M.-7:00 P.M. Posters must fit on a 4-foot high by 8-foot wide poster board. Presenters are expected to be with their posters between 7:00 P.M. 9:30 P.M. Poster must be taken down by 10:00 P.M. Each presenter will be provided with a table and chair, pushpins, scissors, etc.
