Lucien M. Brush Jr., a Johns Hopkins University professor with an international reputation for his study of rivers and the way they carry sediment, pollutants and other materials, died Feb. 13 of cancer at his home in Roland Park. He was 64.
He was a professor in both the civil engineering and the geography and environmental engineering departments at Hopkins. He had joined the faculty in 1969.
M. Gordon "Reds" Wolman, engineering professor and former chairman of the geology and environmental engineering department, described Dr. Brush as a "delightful colleague, with a first-rate scientific understanding, a good teacher and a superb person to work with."
Dr. Brush collaborated with Dr. Wolman on a study of the soundness of plans for a dike to be built around the dredge spoil area at Hart and Miller Islands in Baltimore County.
Dr. Brush was a consultant to many governments, including that China. In 1987, he chaired the American representation in a study of the Yellow River and two years later published a book, "Taming the Yellow River: Silt and Floods."
He studied the frequency of flooding by rivers in the mid-Atlantic region and the effect of land use changes and urbanization on
flooding and river channels.
With his wife, Grace Brush, also a professor in the geography and environmental engineering department, Dr. Brush studied the flow and deposit of pollen grains in lakes and estuaries and applied the information to research on the history of the Chesapeake Bay.
He served on the Maryland Sewage Sludge Management Commission from 1965 to 1968 and on the Governor's Task Force on Dredged Material Management in 1990 and 1991.
His work for Hopkins included service from 1983 to 1985 as associate dean for undergraduate and graduate studies and as the faculty representative to the National Collegiate Athletic Association.
Between 1965 and 1968, he was associate editor of the Journal of Geophysical Research.
Dr. Brush was a former president of the Hopkins chapter of Sigma Xi and was a member of the American Society of Civil Engineers, the International Association for Hydraulic Research and other academic and professional organizations.
He was a member of the Hamilton Street Club and enjoyed golf as a member of the Green Spring Valley Hunt Club.
A memorial service for Dr. Brush will be held at 3 p.m. March 3 in the Garrett Room of the Eisenhower Library on Johns Hopkins' Homewood campus.
In addition to his wife, the former Grace Somers, his survivors include three sons, Lucien N. Brush of Seattle, George S. Brush of Owings Mills and John M. Brush of Baltimore; a sister, Hannah Van Horn of Pittsburgh; and two grandchildren.
The family suggested memorial contributions to the department of geography and environmental engineering or the Athletic Center at Hopkins.
