Abstract

This paper outlines a methodology for conducting systematic literature reviews (SLRs) and meta-analysis studies in geospatial study of flood modelling. This paper offers an advanced and comprehensive appraisal of flood modeling, challenges, and advancements in flood-related studies. The research produced an up-to-date overview of current trends, new advances, and research gaps within the realm of flood and hydrological simulation studies. Subsequent investigation revealed due to the advent of computer applications and advancements in Remote Sensing (RS) data provides an ideal platform for integrating data and technologies for flood prediction. Further, this state-of-the-art review unveils that heuristic and metaheuristic techniques like data-driven tools are widely used in flood prediction with good efficacy. A framework is outlined on how to choose the most appropriate technique or model to address real-world flood-related issues, taking into account by considering the specific model objective, the data available, and computing requirements. However, an additional study has to be done in the flood-prone regions where less research is conducted, which have the potential to forecast floods and mitigate the associated hazards.
