Alden Research Laboratory, Hydraulic research facility in Holden, Massachusetts, US.
The Alden Research Laboratory is a hydraulic research facility in Holden, Massachusetts that studies water flow and hydraulic systems. It features multiple large tanks and specialized instruments that scientists use to conduct experiments related to flood control, river restoration, and water management.
The laboratory was founded in 1894 as part of Worcester Polytechnic Institute and began operations in a former woolen mill. The building was donated by Stephen Salisbury III, marking the start of a long tradition of water engineering research.
The facility works closely with universities to train future engineers and scientists in advanced hydraulic engineering and environmental research. Visitors can observe how academic knowledge translates into practical applications for solving real-world water problems.
The facility is accessible by special tour since it is an active research center with ongoing experiments. Visitors should contact the laboratory in advance to arrange access and inquire about the best times to visit.
The facility houses a steel rotating boom from 1911 that is used for testing hydraulic equipment. This historic apparatus has been recognized as a landmark by the American Society of Mechanical Engineers.
