Never Stop Discovering | Civil and Environmental Engineering


My name is Renske Terwisscha van Scheltinga. I am a PhD student, I was born in the Netherlands. We are in the hydraulic engineering laboratory
of the University of Auckland where we just recorded the video of my flume experiment. This is one of the top places to do research
around the world because of its facilities and because of the big variety of people that work and study
here. In New Zealand you still have natural rivers
so it is a really great place to study rivers. This lab has about 10 different flumes – one
really large one and also a lot of smaller ones. We have a basin of water, downstream, with
pumps we move the water and the sediment upstream and then we recirculate it, and then because
the walls are glass, we can study it from the side and from the top. So we are able to create any feature we
find in nature, so, a tsunami, a river, a river flood. We can study the transport of really big rocks
and also small particles – rocks, pebbles, the gravel… there are actually a lot of names
for different sizes of stones. So if we are going to expect, with climate
change, flooding to be more common and to have bigger floods, we need to adjust. We can’t stop floods from happening but
if we understand them better we can limit the consequences.
