 My name is Renske Tervischa 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 a 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's a really great place to study rivers. This lab has about 10 different flumes, 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 re-circulate it. And 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 of small particles. The rocks, pebbles, the gravels, 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.
