Percolation and related phenomena in porous media

Organized by Robert Ewing

Percolation theory was recognized from its inception as a conceptual model with application to fluid movement in porous media. But while it clearly has much to contribute to our understanding of porous media, it is currently more a curiosity than a tool in the hydrogeological and geophysical mainstream. This mini-symposium will bring together researchers in porous media and percolation theory to examine the connections between the two. What are the applications of percolation theory to porous media? What are the inherent limitations of applying the mathematical theory to physical objects, and what adaptations must be made? Are there related models and/or concepts that can be wedded to percolation theory to broaden its applicability? What critical issues in porous media are currently begging for a solution that percolation theory could provide?

This minisymposium, will be held Monday afternoon of the conference will include the following talks (please click on the titles to see the abstracts):

Conducting polymers and random lasing

Organized by Valy Vardeny

Two topics will be covered in this minisymposium. One is 'random lasers' in which there will be four talks; two talks on experimental works and the other two talks on theoretical issues. The novel and fascinating properties of random lasers are still a mystery, and these talks will give a sample of the many facets associated with this type of laser action. The other topic is 'conducting polymers' in which there will be also four talks, all on experimental works. One talk describes the electrical properties of doped polymers, the other three talks deal with optical properties of several conducting polymer films, including femtosecond transient, cw photomodulation, and spin dependent photomodulation.

Location and weather

Snowbird is a resort complex near the top of Little Cottonwood Canyon, in the Wasatch-Cache National Forest, located 29 miles from Salt Lake International Airport. The conference will be held in the Cliff Lodge, which is a modern, first class resort and business hotel and conference center. It is set at an elevation of about 8000 feet (2440 meters) amidst the spectacular alpine beauty of the Wasatch Mountains, with surrounding peaks reaching to over 11,000 feet (3350 meters). Temperatures and weather conditions during July are generally pleasant, yet in this environment they can be quite variable, with an average daily high of about 85 F (30 C) and an average daily low of about 45 F (8 C). Afternoon mountain thunderstorms are a possibility. The average rainfall in July is about 1.6 inches (40 mm).


We have booked a block of rooms at the Cliff Lodge at Snowbird for the reduced nightly rate of $104.00 plus state tax, currently 10.1% per night. Additionally we have reserved a smaller block of rooms at the Lodge at Snowbird for a nightly rate of $94.00 plus state tax. These blocks of rooms will be reserved until June 14th, 2002, but we urge you to make reservations early since there are a limited number of rooms at these rates. After June 14th Snowbird will continue to accept reservations at these rates on a space available basis.

Reservations should be made directly with Snowbird's Central Reservation Office by phoning 1(800)453-3000. Overseas participants may prefer to make reservations by emailing cres@snowbird.com or by faxing 1(801)947-8227. To get the discounted rates please mention that your booking is in connection with the ETOPIM conference.

For early arrivals and late departures Snowbird can provide guest rooms from July 12th 2001 through July 20th 2001 at the group rate on a space available basis.

We also have reserved a limited number of rooms for students at a special discounted rate. These will be made available to postdocs if they are not all taken by students. Any student or postdoc wanting further information should email us .

Flights to Salt Lake City

Salt Lake City is a major hub of Delta airlines, and is serviced by over 600 daily flights from most major US cities and by many airlines, including United, American, Continental, Southwest and Northwest.

Transport between the airport and Snowbird

Snowbird is 29 miles from Salt Lake International Airport and located near the town of Alta in Little Cottonwood Canyon. Canyon Transportation vans provide transportation between the Salt Lake City Airport to Snowbird Ski and Summer Resort on a daily basis. The trip each way takes about 45 minutes.

Reservations can be made through Snowbird Central Reservations Lodging, telephone 1(800)453-3000. Overseas participants may prefer to make reservations by emailing cres@snowbird.com or by faxing 1(801)947-8227. They should be made 48 hours in advance, and the roundtrip cost is currently $44. The express vehicle to Snowbird runs every 30 minutes, 8am to 10pm, while the return vehicle to the airport runs every hour on the hour, 6am to 8pm. Reservations are preferred for arrivals and required for departures.

If you arrive without a reservation, let the driver know you are attending the ETOPIM conference and you should be able to get the rate of currently $22 each way. If you are arriving or departing outside the normal hours of operation of the express vehicle please contact Canyon Transportation directly at 1(800)255-1841 to make reservations; the one way cost is currently $66 for 1 to 3 passengers, and $22 for each additional passenger.

Attractions in the area

Recreational opportunities in summer at Snowbird include hiking, rock climbing, mountain biking, tennis, swimming, extensive spa facilities, and the Aerial Tram which takes passengers to the top of Hidden Peak in 6 minutes. Deer, elk, mountain goats, and the occasional moose may be seen in the vicinity of Snowbird. Alpine flowers are abundant. There are many other options in the surrounding areas, including bird watching, golf, fishing, boating, hot air ballooning, horseback riding, mountain biking, mountaineering and canyoning, and river rafting.

In Salt Lake City itself there is a wide selection of restaurants, microbreweries, bars, dance clubs, entertainment and shopping. In the downtown area, popular tourist attractions include Temple Square, the Mormon Tabernacle Choir, Ballet West, and the Utah Symphony. Outside downtown the Hansen Planetarium, the Utah Museum of Natural History, the Museum of Fine Arts, the Red Butte Garden, Deseret Village, Tracy Aviary and the Hogle Zoo are worth visiting. Salt Lake City and the surrounding areas hosted the Winter Olympics in February 2002.

Within reasonable driving distance of Salt Lake City are many of America's best National Parks and National Monuments; including to the east (about 4 hours drive) Dinosoar; to the southeast (about 4.5 hours drive) Arches, Canyonlands, and, further away, Mesa Verde; to the south (about 6 to 8 hours drive) Bryce, Capitol Reef, Grand Canyon, Grand Staircase-Escalante, Natural Bridges, Rainbow Bridge (boat trips leave from Wahweap near Page, Arizona), and Zion; to the southwest Great Basin; to the north (about 7 to 10 hours drive) Grand Teton and Yellowstone; and nearby (about 1 hour drive) Timpanogos Cave.

Also worth visiting are a number of State Parks including Antelope Island (see also these photos) in the The Great Salt Lake , Dead Horse Point, Goblin Valley (see also the nearby Little Wild Horse Canyon), and Kodachrome Basin and other playgrounds such as the Bonneville Salt Flats, Cataract Canyon, Desolation and Grey Canyons, Labyrinth Canyon, Little Sahara, Monument Valley, Nine Mile Canyon, the San-Rafael swell, and Westwater Canyon.

Additional attractions include Antelope Canyon, the Bingham Canyon Copper Mine, Buckskin Gulch, Flaming Gorge, Glen Canyon and Lake Powell , the The Great Salt Lake , and the Uinta mountains, and the Wind River Range, and resort towns such as Deer Valley, Jackson Hole, Moab, Park City, and Sundance Resort, and there are also a number of ghost towns and hot springs. In Cedar City there is Utah Shakespearean festival with outdoor play performances during the summer. Further afield, but still within a day driving distance one way by car or bus is Las Vegas

In general the desert areas are very hot in summer and you should be careful to carry plenty of water when driving on remote roads or hiking, and be aware of danger of flash floods in the desert canyons caused by thunderstorms upstream and not necessarily where you are. Be aware of rattlesnakes in the wilderness. Mountains and other high elevation areas (including Bryce, Zion and the north rim of the Grand Canyon) are pleasant during summer.

We hope to arrange an afternoon excursion and several post-conference tours which cover some of the above attractions. More information about Snowbird, Salt Lake City, and Utah can be found at www.snowbird.com, utah.citysearch.com, www.visitsaltlake.com, and www.utah.com. Tickets for many performances in Salt Lake can be obtained through www.arttix.org. A collection of outstanding Utah photos can be found at http://utahpictures.com.
