ABSTRACT
This introduction presents an overview of the key concepts discussed in the subsequent chapters of this book. The book discusses the methods and equations involved in urban flooding modelling. It also discusses the weaknesses of current filters in terms of how they handle landscape and data characteristics. The book covers the formulation of the new filter by a modification of the Progressive Morphological Algorithm. It further discusses the case study performed in this research by covering the selected data, model structure, model set-up, flood events. The comparisons between the results of the flood model using the Digital Terrain Model (DTM) with the new filter, and the results of the flood model using the DTM with the current filter, are discussed in terms of flood depth, flood extent, and flood velocity. The rapid expansion of urban areas over the past two decades has resulted in the extensive growth of many population centres and settlements along coastal, low-lying areas that are prone to flooding.
