Ep 9. Holland's Barriers to the Sea

In the ninth episode of Extreme Engineering season 1, titled "Holland's Barriers to the Sea," host Danny Forster takes viewers to the Netherlands to explore one of the country's most impressive engineering feats: the Delta Works.

The Delta Works are a series of barriers, dams, and sluices designed to protect the Netherlands from flooding caused by storm surges. The country is particularly vulnerable to flooding because much of its land lies below sea level. Without these protective measures, large portions of the country would be inundated by water.

The episode begins with Forster explaining the history of flooding in the Netherlands and the devastating impact it has had on the country. He takes viewers on a tour of an underwater museum that tells the story of the 1953 North Sea flood, which killed nearly 2,000 people. The museum serves as a reminder of why the Delta Works were built.

Forster then visits the Eastern Scheldt Storm Surge Barrier, which he describes as the "crown jewel" of the Delta Works. The barrier is a massive dam that stretches for nearly 5 miles and is designed to protect the Netherlands from storm surges caused by the North Sea. Forster explains that the barrier was built in response to a devastating flood in 1953 and took nearly 10 years to complete.

Next, Forster travels to the Maeslant Storm Surge Barrier, which is located on the outskirts of Rotterdam. The barrier is unique in that it is made up of two massive doors that can swing shut in the event of a storm surge. Forster explains that the doors weigh over 6000 tons each and that the barrier was designed to protect the industrial heartland of the Netherlands from flooding.

Finally, Forster visits the Oosterscheldekering, which is another massive storm surge barrier located on the Oosterschelde estuary. Unlike the Eastern Scheldt and Maeslant barriers, the Oosterscheldekering is designed to allow some water to pass through, preserving the ecosystem of the estuary. Forster explains that the barrier is made up of dozens of individual sections that can be raised and lowered depending on the tide.

Throughout the episode, Forster provides insights into the engineering challenges involved in building the Delta Works. He speaks to the engineers and architects who designed the barriers and explains the various techniques they used to ensure their success. He also provides historical context and explains the importance of the Delta Works to the Netherlands.

Overall, "Holland's Barriers to the Sea" is an engaging and informative episode of Extreme Engineering that highlights the incredible engineering feats that have allowed the Netherlands to thrive despite the threat of flooding. Forster's enthusiasm and expertise make the episode a must-watch for anyone interested in engineering or the history of the Netherlands.
