Laboratory and Annexes

The C. Maxwell Stanley Hydraulics Laboratory is IIHR’s initial and central structure, and it has played a crucial role in the institute’s history. Through the years, it has been remodeled many times to meet changing needs and research approaches. This record group includes the papers related to the construction and physical restructuring of the hydraulics laboratory through time. It also includes material on construction of the ship model towing tank, ice model towing tank, and IIHR’s research annexes.

The record group consists of six archival boxes.
