Race Day
When we arrived at the races, large “START” and “FINISH” banners marked a thin canal in the middle of the University of Twente campus. The width of the sprint course was about 30 feet. Judging from that, the competitors were going to need good control of the canoe or people were going to run into the walls, and perhaps even each other! Assuming that everyone’s paddling skills were going to be similar to our regional and national competitions, the day was sure to be full of concrete canoe carnage.
Very few people were around when we first arrived at the race site, but soon, participants and spectators began pouring in. By the time the races started, the course was lined with spectators and 20 canoes that were ready to go!
Most of the remaining races were similar. Our canoe sustained a large amount of aesthetic damage, but structurally, it faired beautifully. After a brutal t-bone in one of the coed races, we were sure the side would be cracked from top to bottom. However, we found that the damage was mostly aesthetic. Crack propagation was not visible, and the only concrete that broke off was a piece that was placed on for aesthetic purposes. The side of the boat appeared to have flexed four inches or more from the impact!
Thoroughly exhausted, we made our way back the hotel to prepare for the night’s activities. The day was a great success! The competition was fierce, and a lot of fun. Our canoe sustained a lot of damage, but held together amazingly well considering the abuse. |

Competition Day 1
We woke up this morning to a wonderful breakfast, but outside, the weather was not so great. It was drizzling lightly when we arrived at the University of Twente campus and we crossed our fingers that it would let up soon. When we arrived, we found that our canoe had been dropped off by the shipping company. When we saw it, we couldn’t believe our eyes; the shipping company had painted and stenciled our team’s name and logo on the box! Anxiously, we rushed to get the top off and discovered that the canoe received no structural damages from the shipping. Everything was intact and ready for the races.
The jury of judges looked over all the canoes as they were weighed and measured. We had a nice talk with the judges and some of the other teams. Here in the Netherlands, concrete canoe is something they do for several weeks in the summer. Their rules are two pages long and they build a few boats each year. The boats were all painted and looked pretty sharp. From the judging area, we went to a barbecue for dinner and came back afterward for the night’s activities. The sponsors had some kind words for everyone and the organizers spoke briefly. Then, all the participating teams placed their boats in the water and paraded around the pond to show them off. After the banquet, we hung out at a bar on campus and listened to a local band play. We stayed for a short while and decided it would be best to leave and get rest for the races. |

Meetings and Nerves
I am currently waiting for the final three team members to arrive at a train station in the Schiphol airport near Amsterdam. Since my last post, Ivy Harmon and I met up with four other team members: Alex Rexrode, Ann Thielmann, Kelly Greuel and Nicole Brostowitz. Ivy and I have been here for a week and a half now. The other four plan to stay for a week, and arrived on Sunday morning. We met them for dinner on Sunday evening and on Monday, went on a boat tour together. On Tuesday they toured the Science Museum while we checked out some Dutch art and the Van Gogh museum. |

Touring the Sites
| I’m currently on a train with Ivy Harmon (a concrete canoe teammate), returning from our excursion south.
From Amsterdam, we caught a train to Delft, which is located in the southern part of South Holland. I’ve been wondering why Holland and The Netherlands tend to be used synonymously, so here’s what I’ve found: Amsterdam is located in North Holland, and Delft and Rotterdam are in South Holland. South of that is Zeeland. Each is one of the more than 10 provinces in The Netherlands. So now you know. Not all Dutch people are from Holland. For more info look here.
Delft is a gorgeous town. We stayed in a nice hotel on a canal downtown. We also wandered the town for a while, checked out a really old church and climbed the bell tower. The tower was over 300 feet high and had a great view (see the picture below). Delft is pretty expensive and full of tourists, so we saw a few sights and decided to move on. Wednesday morning, we left our hotel around 8 a.m., rented bikes and headed down to Delft Hydraulics where we met up with Jos Dijkman, a flood management engineer. Jos was very welcoming and gave us a presentation on Dutch flood protection. Since the Katrina disaster, American Congressional delegates have been visiting Delft Hydraulics to learn about the stellar protections designed for The Netherlands. The presentation we got in Jos’ office was an abbreviated version of the same one. Very interesting stuff! Jos also showed us some software programs they use. One was able to model flood inundation time and depth within a given dike ring or area, the other was a public relations tool which I’ll explain in more detail next.
The public relations tool was set up for the public who wanted to voice their opinion on any of the over 700 possible partial projects. The program was placed on a CD and was available to anyone, free of charge. It included 3-D renderings of the before and after of the hundreds of possible project portions and a simple interface to switch them on and off. When you made changes, a simple graph of flood peak levels over the entire Rhine delta* would change, showing if you were under the target. The peak had to be below a certain line every where. There is more information here. *The Rhine Delta includes basically all of the Netherlands in a historical perspective. There is more information here. After the presentation, Jos gave us a tour of some of the facilities at Delft Hydraulics. Really amazing stuff. Most things that used to be tested in the physical facilities are now being analyzed with computer simulations. However, they still have to do a lot of physical modeling of wave interactions with silts and sands, and this is mostly what we observed being worked on.
With all our stuff loaded on bikes, we headed south into Zeeland Wednesday afternoon and in the evening we made our way to the town of Ouddorp, where we stayed in a pleasant little hotel overnight. The next morning we were off on a long day of biking across much of the Delta-Works, a series of dams and barriers built after catastrophic flooding in the area in the 50s. The most impressive was the Oosterschelde Barrier which covers about three kilometers of tidal channel. It is normally open and allows over two-thirds of the usual tidal volume. There are more than 60 piers, each weighing an impressive 18,000 tons! This thing was huge and took nearly a half hour to bike across. After crossing the Oosterschelde Barrier, we biked straight into the wind, riding on top of a coastal dike where we went about 10 kilometers per hour into a 40+ kilometer per hour wind. No fun at all. We finally found our way behind the barrier and out of the wind. Needless to say, we were able to make much better time once we were out of the wind. About 30 kilometers later, we had traveled through several smaller towns, two big towns and rode a ferry (see picture below) across a shipping lane to a town called Breskins. In Breskins, we lost our bike route and found a shortcut instead. This was a great thing after spending such a long time on an uncomfortable bike seat. From Breskins it was about 40 kilometers to Brugge, a bustling tourist town in Northern Belgium. Our first night in Brugge featured one of the most fun and delicious meals we’ve had yet. The restaurant was called Bao Bab, an African restaurant run by an eccentric Belgian man who loved giving his patrons a hard time. The cook was his wife and she made some of the most exquisite and tasty meals I’ve ever had. After such a long bike ride, this dinner was a real life saver! We finished around 10:45 p.m. and got back to the hotel, where we passed out in a matter of minutes, completely exhausted from the long journey. The next morning we woke up to what seemed to be the standard continental breakfast here: bread, butter, chocolate syrup, honey, preserves, ham, gouda cheese and summer sausage. The cold cuts were sliced thin and placed on bread with spread. A wide selection of cereal, milk and juice finished off the buffet. A ham and cheese sandwich for breakfast with plenty of butter is actually really good! Brugge was beautiful, scenic and had a lot of interesting museums. We climbed a church tower, and were a foot away from the bells at the 10 a.m. chime; very LOUD bells I might add. The diesel cars on the cobblestone streets were extremely LOUD as well! Also, buses sped by six inches from your shoulder on a two-foot wide sidewalk. It was quite scary! I guess in a way, I’m glad to be away from Brugge, but at the same time if it weren’t for the few downsides, I really would have liked to explore more of the city.
I’ve been typing a mile a minute... slower than our train is going, but fast enough that this has gotten REALLY long. My apologies. We are meeting up with more members of our canoe team tomorrow morning and will be in Amsterdam for three more days. |

Arriving in the Netherlands
| We flew from Madison to Minneapolis, and then directly to Amsterdam Schiphol. From there, it was an easy train ride to Amsterdam Central Station. A fifteen minute walk took us to a beautiful little hotel in the heart of Amsterdam. The Hotel Aspen is three floors, and rests on top of some shops along the street. We have a room in the back overlooking patios and flower gardens. It’s quite clean and great.
For our first day in Amsterdam, we wandered around looking at the sights and enjoying the cool, sunny weather. The amazingly small cars and plethora of bikers is in stark contrast to what we are used to in the states. It’s been a very interesting experience so far. The next update may be a few days; we are heading to Delft and the Delta-Works tomorrow and will be back in Amsterdam toward the end of the week. |

Preparing for the Trip
The team’s preparations are almost complete for our trip to the Netherlands, where we will be competing in the 30th Annual Dutch Concrete Canoe Challenge--also known as the Beton Kanu Challenge. The University of Wisconsin–Madison team was awarded this trip for winning the American Society of Civil Engineers (ASCE) 2007 National Concrete Canoe Competition. Through countless hours of volunteer work done by our more than 25 team members, we secured UW-Madison’s fifth consecutive national championship and the opportunity to compete internationally. Since the USA Nationals, we have reviewed and submitted our technical design paper, and maintained our paddling form and conditioning. With the support of the American Concrete Institute (ACI) and ASCE, our canoe was crated and shipped to Europe. ACI and ASCE also assisted our team by providing flights to and from Europe, as well as food and lodging during the competition. Eight people from the UW-Madison team will participate in the Beton Kanu Challenge. Two of us are arriving on August 26th, and we’ll be touring sights around Amsterdam, Delft and possibly part of Belgium . Four more team members will arrive on August 30th and the final two team members will be arriving September 4, at which point we will head to Enschede, where the competition will be held. We are all thrilled to be given such an amazing opportunity to represent the USA and to experience a different part of the world. I am especially excited to see some of the flood protection constructed over the past several centuries in the Netherlands, and our planned visits to Delft Hydraulics (http://www.wldelft.nl/) and the Delta works (http://www.deltawerken.com/). The lab in Delft is going to be a great opportunity to learn more about some of the latest research in the field of sediment transport, fluid mechanics and water wave theory. Seeing the structures of the Delta works, some of which are built to withstand 4,000-10,000 year storm events, will be an amazing experience. |


After our tour in Delft, we visited the Maeslant Barrier. This Barrier was HUGE! It was 22 meters tall from top to bottom, and if stood on end, it would be taller than the Eiffel Tower. The huge ball joint at the inland side is 10 meters across. It resides in large dry docks and when flooded, causes the barrier to float. Once floating, the gates are rotated together to close the shipping lane. Once closed, they are sunk to the bottom by filling them with water. This barrier, because of the high value of what it protects, was designed to protect against the 3,000-4,000 year event. With a failure probability of something like 1 in 10,000 years. Really amazing stuff.
So here we are on a train going what feels like 100 miles an hour on our way to return the bikes to where we rented them in Delft.
