Andy Chia-An Ku BSc MSc

PhD Candidate

My research focuses on integrating agent-based land-use modelling and flood modelling for evaluating the effectiveness of land-use based flood management strategies in urban environment.

Biography

I got my first degree in geography from National Taiwan University, where I spent most of the time studying the combination of remote-sensing and GIS techniques for evaluating the impervious surface area in Taipei City. Because of my strong interest in understanding the relationship between human behaviour and urban environment, I decided to pursue a Masters degree in urban planning, which focused on simulating the impacts of extreme floods on land-use patterns, based on a Markovian cellular automata model in Taipei City.

After graduation, I started to focus more on agent-based models and assisted in the construction of a simulation framework for a land-use modelling project funded by National Science Council of Taiwan. I had also worked as a full-time urban planner in an engineering consulting firm where I was in charge of the land-use planning for the Mass Rapid Transit system in Taoyuan City, Taiwan. Afterwards, I was awarded a 3-year Taiwanese government scholarship in the field of disaster management. In my PhD study, I will combine my previous experiences in urban planning and modelling in order to construct an integrated framework for evaluating the effectiveness of land-use based flood management strategies, which aims at reducing the flood risks in the future.

Research

In order to reduce the possible effects of flooding under extreme weather events, relevant strategies have been proposed, based on a risk management perspective, to set up more flexible and effective flood risk reduction methods by risk evaluation and adjustment. Among these strategies, land-use control is increasingly considered one of the most feasible solutions because of its ability to manage the characteristics of flood by altering the conditions of flood occurrence, and thus decreasing the overall damage it might cause in the long run.

Thus, there have increasingly been studies emphasising the influences of land-use changes on flood behaviour. However, these have failed to evaluate land-use based strategies effectively, because of the difficulties in dealing with uncertain spatial and temporal relationships between land-use changes and floods, understanding of which is crucial in helping policy makers to assess the feasibility of proposed flood management methods.

On the other hand, land-use patterns in urban areas can also be influenced by floods, as a result of risk perceptions and the adaptive behaviour of people. Therefore, it is necessary simultaneously to consider these two processes in an integrated framework because of their strong spatial and temporal inter-relationships. My study accordingly aims to develop an integrated simulation framework which is able to capture their dynamic relationship. It will focus on the capital of Taiwan, Taipei City, as a case study: this city has experienced increasing flood events over the past decade, which have caused severe damage.

The objectives of my study are (1) to systematize possible land-use based flood management strategies drawing on case studies and literature review; (2) to simulate possible land-use patterns in the future based on an agent-based model; (3) to model the potential flooded areas and depths of different scenarios by a 2D inundation model; and (4) to quantify the flood exposure and damage resulting from different strategies by depth-damage curves. The results of my research could be a solid reference point for developing the best combination of strategies for managing future flood risk in the study area, which aims at reducing the urban flood risk effectively in the future.
