Darcy’s famous sand column.

The 2003 symposium will be divided into four sections:• Open channel flow• Closed conduit and pipe hydraulics,• Groundwater and porous media flow, and• Hydraulic instrumentation.

Each section will consist of a quick review of Henry Darcy's work in the topic area, followed by technical papers on others researchers. As previous writers, such as Rouse and Ince (1957) and Rouse (1976), have provided historic overviews for the earlier hydraulics work, it is hoped that most papers will address persons and developments of the last 50 years. To minimize discord, biographies will only be accepted for persons who are deceased or no longer professionally active.

The symposium's papers be published as a special proceedings shortly after the symposium.

DARCY MEMORIAL SYMPOSIUM ON THE HISTORY OF HYDRAULICS

ASCE/EWRI National Meeting, Philadelphia, PA, 2003

Henry Darcy

The SymposiumJune 10th, 2003 will mark the 200th anniversary of the birth of Henry Philibert Gaspard Darcy (1803-1858). Darcy was a person of unusual ability and accomplishment. He is credited with inventing the modern style Pitot tube, was the first researcher to suspect the existence of the boundary layer in fluid flow, contributed in the development of the Darcy-Weisbach equation for pipe flow resistance, made major contributions to open channel flow research, provided the first quantitative measurements of artesian well flow, and of course developed Darcy's Law for flow in porous media.

To celebrate the anniversary and to draw appropriate recognition to Darcy's work and the work of other prominent hydraulicians, a task committee is planning a specialty symposium to be held during EWRI's hydraulics and water-resources conference in 2003. ASCE's Environmental and Water Resources Institute (EWRI) has recently established the task committee, which aims generally at researching and publishing information on the history of hydraulics research and engineering, including biographical accounts of prominent hydraulicians. The specialty symposium in 2003 will commemorate Darcy's accomplishments, as well as provide a forum to remember the accomplishments and contributions of more recent hydraulicians. Papers are sought that address either the history of a given hydraulics topic or the biography of a practitioner who made a major contribution in hydraulics.
