Due to a rapid increase in urban and built-up areas, the East Coast – Gulf basin of Thailand faces flood hazards more frequently than in the past. In this study, we aim to assess the effects of building construction on flooding, and any link between them. The FloodMap model is used to simulate flooding in the study area in September 2015. Two flooding scenarios were designed; one based only on land surface elevation and the other one with building construction included on the land surface. According to the result, we found that human construction increases flood hazard in the study areas, particularly flood depth. Flood areas are also found to increase if the human factor is added into the model, but in a lesser extent. With human construction, paved road is found to have the highest flood potential compared to other types of road. Built up areas are more flooded, while flooding extent is almost similar to results from the scenario of no human construction in forest and agricultural areas.
