With a view to avoiding overlap with the main subjects of the Rome conference being held in October 86 and in order to emphasize the regional character of the French workshop, the scientific committee of the workshop has decided, in full agreement with E.W.E.A. council, to allocate subject No. III to the French authors only.

PRELIMINARY PROGRAM FOR ASCE INTERDIVISIONAL CONFERENCE ON ADVANCEMENTS IN AERODYNAMICS, MECHANICS AND HYDRAULICS
FLUID
3--6 June 1986, Minneapolis, Minnesota The above conference will present advanced fluid mechanics applications in engineering and related areas. The preliminary program identifies 148 papers which will be presented in three parallel tracks.
101 Track I
Covering the topical areas of turbulence measurement and modelling, computational fluid mechanics, vortex flow, and physical modelling. Track H
Cavitation and two-phase flow, flow over bodies and fluidstructure interaction, architectural aerodynamics. Track III
Environmental fluid mechanics, sedimentation, granular flow, pipelines, stratified flow, and porous media flow. Each track will have several invited k e y n o t e lectures of 40 minutes duration each. Fourteen k e y n o t e lecturers have accepted to make presentations in a staggered schedule during the three and one-half day conference. In addition, each day will open with a plenary session for a different subject track. The speakers will be Professor Norman E. Brooks, CalTech (Hunter Rouse Lecture), Professor Jack Cermak, Colorado State University, and Professor John Lumley, Cornell University. A copy of the proceedings will be available at the time of the conference. Technical tours will be offered on the afternoon of June 6. The final program will be distributed in March. The weather will be suitable for sight-seeing trips in the Twin-Cities area, to Minnesota lakes, or Lake Superior after the conference. Individuals or organizations interested in the program should contact: Ms. Sandra Peterson, St. Anthony Falls Hydraulic Laboratory, University of Minnesota, Mississippi River at 3rd Avenue S.E., Minneapolis, MN 55414, U.S.A.

T H I R D I N T E R N A T I O N A L WORKSHOP ON WIND AND WATER T U N N E L M O D E L L I N G OF ATMOSPHERIC FLOW AND DISPERSION This E U R A S A P sponsored meeting will be held at the Ecole Polytechnique Federale de Lausanne from the 15th to 17th September, 1986. The workshop will be followed by an optional visit to the rotating platform facility at Grenoble and the wind tunnel facilities at L y o n on the 18th and 19th. The Workshop will follow the same format as the previous two meetings at Apeldoorn and Oxford, and papers are sought on topics coming within the general area of the physical modelling of atmospheric flow and dispersion. The meeting is being jointly organised by: Dr. A.G. Robins, Dr. J.A. Hertig,
