The Netherlands is great for a mechanical engineer and
environmental scientist like Tom and I. There are water projects all over the
place and living below sea level is a surprise. We first realized that we were below mean sea level (below mls)
when driving on the A58 here in Zeeland. As we passed under a canal there was a sailboat sailing over
us!
Then in Oegstgeester, our elevation below msl was confirmed.
We saw a cow grazing next to a sailboat. The sailboat at sea level and the cow
and pasture below msl. These low-lying areas enclosed by dikes that are formed
from reclaimed lands.

In my opinion, the windmill is the most romantic water pump
every built. Not only is it beautiful it is elegant in construction. Windmills
use scoops on water wheels and Archimedes screws to move the water from the
well like shaft into the canal and onward to the sea. The canvas sails point
into the wind and supplies the pumping power. The entire top of the mill can be moved around on wooden
wheels to point into the shifting wind.
Even though they say that there are 1150 working windmill in Holland (http://www.windmillworld.com/europe/netherlands.htm) and
their presence in the landscape is a constant reminder that we are living below
sea level.

Don’t you love the sound of the wind in the sails?
We visited the Neeltje Jans. No I can't pronounce the words either. Nor can I say Oegstgeester. I just don’t think we can put “ltje” together in
English... sigh. As an aside, there is a town nearby called Vlissengen. Yep, also can't say it. But there was a similar town in Queens, New York which used to be called Vlissengen back when New York was New Amsterdam. Now is is called Flushing. The British I guess couldn't say it either. Flusing is anglicized but sounds like Vlissengen.
Back to water and great hydro projects. The Neeltje Jans are part of the 13 dams of the Delta Works/Zuiderzee
project. This project was declared to be on of the Seven Wonders of the
Modern World by the American Society of Civil Engineers along with projects like the Channel Tunnel and our very own
Golden Gate Bridge. We visited the dams between Schouwen-Dulveland and
Noord-Beveland both islands to the north of us. These barriers were
initiated after the 1953 floods where the North Sea storm surges raised sea
level up to 18.4 feet. Yikes!

The giant gates were open during our visit and the elevation of the sea was the same on the day of our visit. During storms the gates can be lowered by the giant rams to protect the low lands from flooding.
