April 25, 2022 - "The Oosterschelde storm surge barrier (1976-1986)
The construction of the 9 kilometer long storm surge barrier the “Oosterscheldekering” is a complex and unique project. A structure of such enormous dimensions has never been built. The barrier consists of 65 pillars of 30 to 40 meters high and 62 sliders of 42 meters wide and 6 to 12 meters high. That makes the defense barrier (cost 2.5 billion euro) one of the most impressive hydraulic constructions in The Netherlands.
A lot of discussion precedes the construction of the barrier. At first, the plan is to close off the Oosterschelde with a solid dam. However, fishermen and nature conservationists revolt against this plan. The Oosterschelde is a unique nature reserve with more than 70 species of fish, 140 species of aquatic plants and algae and 350 species of benthic animals, which live on the sea bed. Building a solid dam would result in this nature reserve suffering irreparable damage.
Oosterschelde Open
Completely closing off the sea arm means the end of the salt water environment in the Oosterschelde and therefore also the cultivation of mussels and oysters. The protest – with the Oosterschelde Open as battle cry – does not fall on deaf ears. In 1975, the then Cabinet came up with the proposal to build an open barrier that could be closed by means of gates – if necessary.
A permeable barrier is much more expensive than a solid dam and thus the Cabinet’s proposal leads to fierce debates. In 1979 parliament approved the plan for the construction of the Oosterscheldekering." Previous text from the following website: watersnoodmuseum.nl/en/knowledgecentre/the-oosterschelde-...
January 9, 2021 - "This span is an iconic connection between the historic district of the City of Dublin and a new commercial district across the Scioto River to the east, enhancing the character of the surrounding historic neighborhood with a modern iconic element. The bridge connects parkland 40 feet below the bridge deck with the eastern bank of the Scioto. Located in the Midwest, the design is for a two span (350-foot each), 700-foot total length by 14 foot wide pedestrian bridge. The bridge deck is “S” shaped in plan with a radius of 500 foot and is anchored into the earth at the embankments."

September 11, 2024 - Glen Canyon Dam, rising 710 feet above bedrock within the steep, rust-colored sand-stone walls of Glen Canyon, was constructed to harness the power of the Colorado River in order to provide for the water and power needs of millions of people in the West.
Glen Canyon Dam is the second highest concrete-arch dam in the United States, second only to Hoover Dam which stands at 726 feet. The 25.16 million acre-feet of water storage capacity in Lake Powell, created by Glen Canyon Dam, serves as a ‘bank account’ of water that is drawn on in times of drought. This stored water has made it possible to successfully weather extended dry periods by sustaining the needs of cities, industries, and agriculture throughout the West.
Hydroelectric power produced by the dam’s eight generators helps meet the electrical needs of the West’s rapidly growing population. With a total capacity of 1,320 megawatts, Glen Canyon Powerplant produces around five billion kilowatt-hours of hydroelectric power annually which is distributed by the Western Area Power Administration to Wyoming, Utah, Colorado, New Mexico, Arizona, Nevada, and Nebraska. In addition, revenues from production of hydropower help fund many important environmental programs associated with Glen and Grand canyons.
The designation of Glen Canyon National Recreation Area in 1972, underscores the value and importance of the recreation benefits associated with Lake Powell and the Colorado River downstream of the dam. The recreation area is managed by the National Park Service.
Glen Canyon Dam is the key water storage unit of the Colorado River Storage Project, one of the most complex and extensive river resource developments in the world. Without it, development of the Upper Colorado River Basin states’ portion of the Colorado River would not have been possible." Previous description: www.usbr.gov/uc/rm/crsp/gc/

June 29, 2017 - I actually recorded a seven minute video of us being lowered in the lift however it is way to large to post on Flickr. It was an exciting experience! Sailing aboard Chang Jiang SanXia 5 in the Ship Lock Lift which allows ships to be raised/lowered to pass the Three Gorges Dam. This saves time instead of navigating through the lock system at the dam which larger ships must navigate. Three Gorges Dam located in the Hubei province, China.

June 21, 2023 - Returning to the Port de Carcassonne from our cruise on the Canal du Midi. The canal was declared a UNESCO World Heritage Site in 1996. It was designed by engineer Pierre-Paul Riquet and was constructed between 1667 and 1694 it links the Mediterranean Sea and the Atlantic Ocean.
