L12. Advances in flood inundation modelling

In the past century, major efforts have been devoted to the modelling of flood inundation leading to substantial improvements in related methodologies. The modelling will however always be a challenging one because of the complexity and chaotic nature of the system. In recent years, there have been significant advances made in flood inundation modelling to cater for various needs such as flood risk mapping, flood damage assessment, real-time flood forecasting, hydraulic engineering, water resources planning, as well as having served as an important prerequisite to support other flood related decision making. These advances have been achieved through improving modelling structures and algorithms, data assimilation integrating remote sensing techniques, combining different modelling approaches, adopting the latest computing technology, etc. With these advances, it has now become possible to model large scale floodplains of several thousands of km2 for multiple flood events with relatively high computational efficiency. Another aspect of advances in flood inundation modelling is the quantitative estimates of uncertainty associated with floodplain inundation simulation and prediction. These advances have led to practical applications of rapid real-time inundation modelling and forecasting. This session invites papers dealing with various aspects of advances in flood inundation modelling such as:
