Hydraulics

The first wave pool in North America to consistently generate 3-5 foot spilling waves suitable for surfing

Big Surf Waterpark uses 15 gates that empty water into a 2.5 acre lagoon with contours that replicate a natural beach. Waves are produced by pumping water to a pre-selected height and released through underwater gates. The water released breaks over a baffle (similar to a natural reef), forming one wave per cycle. Water is recirculated to the lagoon through pumps.

The Hydraulics Laboratory at The University of Iowa, renovated in 2001 and in 2003 renamed the C. Maxwell Stanley Hydraulics Laboratory, is the oldest university-based hydraulics laboratory in the U.S. that continuously has focused on research, education, and service in hydraulic engineering. Since its initial construction in 1919, the facility and staff have produced a massive amount of research that has shaped water-related constructs around the world. Its efforts have been guided by noted directors such as Floyd Nagler (1920-1933), Hunter Rouse (1944-1965), and John F.

Morris Canal was built to transport coal from the Lehigh Valley of Pennsylvania to industrial markets in Newark and New York. The total length of the canal was 106 miles. The canal climbed an astonishing 914 feet from Newark Bay to the summit at Lake Hopatcong, and then dropped 760 feet to the Delaware River at Phillipsburg. This gave the canal an average vertical slope of 18 feet per mile, steep compared to the contemporary Erie Canal's relatively gentle slope of one foot per mile.  

The 367-80 is the prototype for most jet transports. Its success was due largely to its mechanical systems, including turbine engines with thrust reversers and noise suppressors, redundant hydraulic control systems, and an improved cabin-pressurization system. Honeycomb flap panels were introduced, along with a strong, lightweight structural design that controlled fatigue cracking. These led to several innovations in aircraft tooling and manufacturing techniques. The Dash-80 was the first commercial airliner economical enough to take the US airline industry off subsidy.
