all those guilty of such things, you know who you are. I almost want to slap myself for it, but figured this is one of those occurrences I must make known in a public cry for help.
Here are mostly photos from the field trip I took out to see the barriers over a couple of days in Zeeland and elsewhere of the Deltawerken, the Delta Works Projects. I will avoid going into too much detail (if you want it, email me or wait for my report) so I’ll just show the pics and include a few basics. Delta” refers to the Delta of the Rhine-Meuse (Maas)-Scheldte rivers. For more details online, check out http://www.deltawerken.com/
The suffix “kering” means “barrier” in Dutch. It… was… huge… (you will notice a theme). Sadly the photo doesn’t do it justice, but here is Matthijs in front of it to give you kind of an idea. And no, I didn't fly my heli-overhead to get the shot, I borrowed it from online.
(I did take this one though)
Apparently they used a crappy grade steel when initially constructing it which means they have more maintenance than they would like. Costly, but they will still do it due to safety.
Matthijs (pronounced: Ma-tie-us/Mathias) is a kind, kind, and really smart man. I was put in touch with him by one of my professors from UC-Berkeley. He is a risk-management consultant/”expert” for the country and a part time professor at the Technical University in Delft. He spent time with me all day driving me around the area looking at flood-defence sights and showing me the massive amounts of greenhouses in this part of the country (which I accidentally deleted the photos).
They use so many greenhouses to extend the growing season (it’s cold here!) and export. From what I could tell it was mostly tomatoes and peppers. Interestingly enough, there are enough greenhouses in this area that the rainwater from the roofs actually is an issue for drainage and flooding.
I told Matthijs that if I can’t find a job in the US, I’ll be back to competing with the Polish migrants for the greenhouse jobs. He apparently thought that was funny. I ended up with free dinner Tuesday night, so my humor must be getting me some points (or pity).
I learned a ton and we had great discussions on flood policy approaches in the Netherlands and the US. Incidentally, he does not understand us and our flood policy—why we wont’ step it up when we know things aren’t right. Go figure, neither do I.
Haringvliet Sluices
Near the Haringvliet estuary, these are sluices which have a long arm extending down, to provide a barrier to the North Sea during flood conditions, a storm surge, and twice a day during high tide. This barrier works to control the river and water levels in a large part of the country. On one side of the barrier is the North Sea and on the other side are the Rhine and Maas Rivers.
Construction period from 1956-1971
It was pretty cool and they take you on a tour of it after watching a video on construction (all in Dutch), you can even go inside.
Bear thought he looked rather regal in the wind, so here.

The gates are 10.5 meters high. so about 5 meters protrude above the normal water level.
Oosterscheldekering (Oh-sta-schkell-da-kerin)


Some might argue that Bear is actually looking at the D>50 (grainsize) on the levee. You have to be a hydrologist to appreciate that terrible joke (thanks KP).
Fishermen at the edge of the barrier. This is the North Sea on the left, and the river draining through is the Scheldte.
The construction of this barrier was incredible. They built 3 islands/land masses and then connected them by this giant barrier/dam. I think an aerial photograph would best explain it.
All of this land has been "reclaimed" from the sea. This process of reclaiming land from the is not unlike parts of New Orleans or the Sacramento-San Joaquin Delta in California, though it is a much grander scale here in Holland.
Lastly, after the visit at the museums, I drove the rest of the way across the Oosterscheldekering, got off the main road, parked my car and sat on the beach next to this barrier for quite some time. I even put my feet in the North Sea. I was told this was cold water, but growing up on the Great Lakes, I really could not agree. J
