 Hey everyone, my name's Harry and I'm a fourth year environmental engineering student here at the University of Newcastle. And my name's Chelsea and I'm also a fourth year environmental engineering student as well as a Bachelor of Science. So for our project the problem was really assessing the flood impact on this development and we were acting as the consultant in this in this role. So we were presented with a problem about a development. Is it going to be suitable and sustainable? And then we do the COX quantify what's going on in that catchment and we hand it back. So the first step was to actually work out the real-world parameters and that might be how much land is covered by grass? What sort of areas covered by concrete? What are the catchment features like roads and dams and ponds? And they're really important and pretty much converting those real-world things into a computer or a mathematical idea within our model. And then the next thing that we're going to do is put the development into the model. If it means that there is water coming into the houses, if it's going to cross the road and what kind of like categories that is. Moving forward I guess this development is not going to last 10 years. It's going to be people's lives. They're going to be living there. And so there's also within local government areas the requirement to plan for the future. So once we had our model and our results we used was geographical information systems. So behind every solution there's hundreds of problems and this project was not short of problems. Obviously flooding it's a very emotional personal experience if you've ever gone through it. And so trying to communicate our like numbers and facts through to clients or decision-makers and making sure that they understand the full extent of it that's been a difficult challenge. Yeah, so it's really important that Chelsea and I as young engineers get our experience up in real-world modeling. So to be able to work out and get some real-world experience in quantifying the effects that that might have is something that was really important for us and it's going to put us in good stead for when we head into industry.
