Assam is a state in Northeast India facing floods every year which leads to human misery and devastation of nature. The objective of this review is to explore the natural and anthropogenic factors causing flood in Assam over a period of 11 years. The SCOPUS, Science Direct, and Web of Science databases were searched to identify relevant studies in Assam. The outcome of interest was to identify the natural and anthropogenic factors that contributed to the occurrence of floods in Assam from 2010 to 2020. Data were charted and reported in accordance with the “PRISMA guidelines.” From 1582 screened citations, 54 articles went under full-text screening, among which 35 studies were eligible for this review. Rainfall events, climate change, urbanization, deforestation, improper drainage and embankment construction contributed most. This review concludes that anthropogenic factors outweigh the natural factors for flood occurrence in Assam.
