Administrative Advisor Allen Mitchell (University of Alaska) reported that the narrative section for this year’s annual report would be limited to 12,000 words, which would limit the information that could be contained in the report, especially the impacts section. Don Nielsen mentioned that the annual report should contain at least the references from the members, so that interested parties could research the activities. Ray Knighton thought that W-188 section should produce an executive summary with the impact statement and references, and then place the complete report on the W-188 web site ( This option appeared to garner the most support from the members, many of who have already completed their institutions’s report. Allen will generate the executive summary and place it at Appendix D in the National report. As before, the guidelines for the report are found at Report sections should be sent to Michael Young, W-188 secretary, for assembly and distribution. The full report will be sent to Allen Mitchell by February 15, 2002.

Ray Knighton (CSREES) gave the CSREES representative's report and provided a two-page summary of the budget status for fiscal year 2002 (FY02). He stated that FY02 funding for CSREES was $1,024,388,000, an increase of just under $43 million over FY01 budget. The NRI budget was increased by about $15 million, while special grants was decreased by just over $2 million. Almost $43 million was provided for the new Integrated Activities account, representing an increase from FY01 of approximately $1 million. Unfortunately, the IFAFS program was not funded in this funding cycle, though Ray thought that it could be revived in a future farm bill amendment, or it could receive strong consideration in the FY03 budget. Ray described several new research initiatives being developed that would provide additional research funds. The first is the Section 406 Water Quality, which will form a new collaboration with EPA, possibly focusing on nutrient management. The National Climate Change Technologies Initiative was proposed by the Bush administration as a response to the non-participation in the Kyoto protocol. This initiative would focus on greenhouse gas emissions. Technical support papers were being written in Washington to support this area, and many discussions are being held between agriculture and industry. Ray also mentioned that the S1004 group had formed to deal with total maximum daily load (TMDL) issues. Because this group is dealing with the scaling issues and modeling, Ray feels that the W-188 group could contribute some expertise. He indicated that he would provide that group with the W-188 member name, and objectives for model validation.

The business meeting followed the CSREES representative's report. The annual report and minutes of the previous meeting (Jan. 3-5, 2001) were approved unanimously. Nominations were taken for new committee members. The nominees were: Scott Jones (Utah State University) and Markus Tuller (University of Idaho). Nominees were voted on and approved unanimously. Michael Young nominated Frank Casey to be next year’s secretary; he was elected unopposed. The location of next year's meeting was discussed briefly. Most of the attendees found the accommodations at Circus Circus favorable, though others felt it was time for a change. Michael Young indicated that he would search for other possible accommodations, but that timing, and thus cost, was important given large conventions that are in Las Vegas at the same time as W-188. He will communicate to the group through email. The cost for this year's meeting was $80 per person.

With respect to new business, Gerard Kluitenberg announced that S-1 had voted to approve an S-1 Early Career Award for those scientists who are within six years of obtaining their Ph.D. Kurt Pennell has the information on this award on the S-1 soil physics web site ( Michael Young mentioned that AGU was combining their Spring 2003 meeting with the European Geophysics Society, to be held in Nice, France in May, 2003. AGU was soliciting central themes for this meeting. Suggestions should be forwarded to the Unsaturated Zone Committee of the AGU in the near future.

The technical presentations commenced with presentations from the University of Arizona. Ty Ferré discussed the borehole GPR method of identifying wetting fronts. Art Warrick presented results on the use of analytic elements for simulating the presence of multiple impermeable objects. Laosheng Wu (University of California, Riverside) described the effects of applying polymers (e.g., polyacrylamide) on the sorption of pesticides. Dani Or (Utah State University) presented a list of his on-going projects and introduced Scott Jones (Utah State University), who is studying the use TDR to measure water content in cereal grains. Mike Sukop (Utah State University) presented research on the use of Lattice Boltzmann models for simulated fluid movement in porous media. Gerard Kluitenburg described new solutions for the dual-probe heat pulse meter, including comparisons of errors associated with probe orientation.

After lunch, the technical presentations continued with Bob Horton (Iowa State University) who described the use of the heat pulse sensor to measure subsurface flux. Dan Jaynes (USDA, National Tilth Lab, Ames, IA) described the use of cluster analysis to describe spatial distribution of corn yield. Jan Hendrickx discussed geophysical methodologies for detecting land mines. Glendon Gee (Batelle Pacific Northwest National Labs, Richland, WA) presented the water flux meter for directly measuring subsurface flux. Michael Young (DRI, Las Vegas, NV) discussed modeling efforts to simulate flux at the Savannah River Site, SC. Bill Albright (DRI, Reno, NV) presented the Alternative Cover Assessment Project, which compares flux rates through prescriptive and monolithic covers in different geographic areas of the US. Lehua Pan (Lawrence Berkeley National Labs, Berkeley, CA) described modeling activities using TOUGH2 code to simulate fracture flow at Yucca Mountain, NV. All participants were invited to a social hour in Don and Joanne Nielsen's room.

The technical presentations continued the following morning (Jan. 4) at 8:30. This was the final day of the meeting. Joan Wu (Washington State University, Pullman) began the day’s presentations by discussing modifications to the WEPP model and to the CLIGEN climate generation. Markus Flury (Washington State University, Pullman) described a new technique for measuring soil water retention curves by freezing and thawing the soil sample. Greg Butters (Colorado State University, Fort Collins) presented the results of an automated experimental method and inverse modeling, for obtaining water retention curves in soils. Time Green (USDA-ARS, Fort Collins, CO) described the use of artificial neural networks and geostatistics to study the yield of winter wheat.

A number of presentations by scientists at the USDA-ARS-USSL, Riverside, CA commenced with Scott Bradford, who presented experimental results of cryptosporidium parvum and giardia movement and release from waste material as a function of solution salinity. Marcel Schaap described a method of simulating fluid flow in porous media using the Lattice Boltzmann model. Paolo Castiglione presented laboratory and numerical results using the dual permeability model to simulate preferential flow in large soil columns.

After lunch, the presentations continued with Frank Casey (North Dakota State University), who described a method for field-scale solute transport prediction using a mechanistic-stochastic model. John Nieber described the modeling of unstable water flow using higher-order corrections to Richard's equation. Phil Meyer (Batelle Pacific Northwest National Labs, Portland, WA) demonstrated new software developed at PNL for estimating vadose zone water fluxes for identifying potential disposal sites. Markus Tuller presented new methods for modeling unsaturated soil hydraulic properties. Frank Schwartz (USDA-ARS, Bushland, TX) presented new sensor technologies for measuring soil water content. The meeting was adjourned around 16:30. Afterward, all were invited to a social hour in Don and Joanne Nielsen's room.
