 Hi, my name is Emilian, I'm from Indonesia, so actually I was a ten-year lecture at Water Resources Engineering Department in Ravica University, Indonesia, so I've been working there since 2014 and I have a background as a coastal engineer with a master's degree from the University of Miyazaki, Japan and my focus is in coastal pathological modeling. My name is Uve Best and I'm from Guyana, it's a country along the South American coastline and I'm a civil engineer with a specialty in coastal engineering and my specialty was actually gained right here at IHE Delft in one of the MSc programs, Coastal Engineering and Port Development. I chose IHE to pursue my PhD because I know that the coastal engineering group research at IHE is very well known for its expertise in coastal modeling so I know some of their models such as Delft 3D, X-Beach and also the latest and the four for my promoter, Professor Donorolving, he also developed this newly a model called ShoeNS, so that's why I would like to do my PhD at IHE. During my MSc research I was fortunate to be able to work on the coastal dynamics along the Guyana coastline but even before then I worked as a civil engineer with the ministry in Guyana and it's there that I really developed a passion for coastal engineering. So my research would be the mangrove modeling dynamics in a programming delta so it is actually I would like to study the interaction between mangrove and mag flat by developing by developing a couple of models with an individual based mangrove model which is actually modeling each trees so I can track and detect for their growth their interaction between mangroves and also with landscape development. And why did you choose Parang as your research location? Okay so Parang is quite important in my country because in May 2006 there was a volcanic mud eruption there so it is even considered as the largest mud eruption in the world and because of that disaster so like more than of 60 000 people have to be evacuated from the area because like a lot of mud have in have inundated area so they have to move and my government the government of Indonesia they have to build like a diverse structure to divert the mud from that particular area to the nearest river because if they don't divert that low the mud flow the the area will be much more inundated so they created some kind of a diverse instructor and they flow the mud into the river because of that so we see that the rapid development of delta in the downstream and one of the effect of that diversion is we see the growth of the mangrove and it is nice because the dataset on mangrove mud flat and sediment flow it is quite scarce in in our area in our subject in our research so with that kind of disaster I found that the government have like almost 12 years of observation so that I can make use of that observation to build my portal and then to analyze the interaction between mangrove and mud flat we should be able to analyze what will be the future of the delta so we will have less impact to the people live nearby that was my next question was what do you hope is the benefit of your research to the area but also to the contribution to the SDGs okay so luckily by having this kind of analysis so I can show to the government so this will be the future of the portal but in the other hand I can also deliver so I can also give some kind of contribution to community that I have a working model with interaction of mangrove and mud flat and they can use that model to assess the location or to analyze what or to quantify the interaction between mangrove and also landscape in their particular study area so it is not bounded in in Indonesia you can use it for every location okay thank you can you explain why mangrove conservation through restoration is so important for your country definitely Ruth and I think it's a really good question so contrary to the sandy coastlines that we're most familiar with along several beaches whether it's in Netherlands or within Europe geonics coastline is developed by these massive mud banks which are about 20 kilometers wide and they move along shore and whenever these banks are in front of an area you have the coastline becoming stable and prograding but in their absence you have a lot of erosion and this increased erosion is usually what instigates the loss of the mangroves and so when you talk about mangrove restoration you have to look at the benefits of it Gannis coastal area is flat it's below sea level and so it's vulnerable to sea level rise but it's also quite an essential area because it be used for agriculture or capital cities there or ports are there and so when managing the use of such a valuable and vulnerable area you really have to have an understanding of what are the processes governing the overall development of that area and so the use of mangroves allows us to step beyond the whole line approach that several hard structures usually encompass and it allows for us to not only advance the coastline but also reclaim several areas that have been lost to the Atlantic Ocean so the question really isn't why do we use or want to restore the mangroves but more so how we can integrate them properly within the coastal strategies great very interesting and what is your own research hoping to achieve well thank you for the question so my research is actually two-fold it hopes to first assess the mangrove dynamics with regards to sea level rise and increasing waves and also to really look at how effective the combination of hybrid approaches are with regards to coastal protection for example in Guyana we use the sea walls with the mangroves and in other countries they combine the mangroves with offshore breakwater is and so looking at the effectiveness of such combinations I really feel would add a great value to the discussion on on how we can include the mangroves within coastal protection measures and interestingly both of you are doing your research into mangroves and I imagine that you collaborate to a certain extent can you explain a little bit more about the link between if there is one between your two pieces of research so wonderful question right these are indeed different projects they're in different parts of the world different mangrove species different situations that resulted in us focusing on them but definitely the overall idea is that we need more monitoring we need more days to be collected and it's only with that that we can improve the message that is being carried out on protecting and conserving the mangroves and also by collecting some deficits we also develop a model so we're developing a transit model which is actually trying to solve the processes but in my project I am actually developing a landscape model which is actually can solve the interaction between mangrove and mangrove plants
