In commemoration of Engineer Week, this program is dedicated to the USACE San Francisco District’s construction of the Bay Model. This former one-of-kind scientific, hydrodynamic, engineering testing facility has accurately produced water related predictions for almost a half century. The first 30 years it was all hand operated. How did they do it? How was the information used? Although retired now, this story is part of the districts amazing legacy. Join Ranger Linda for more.
