HYDRO-GEOMORPHOLOGICAL DYNAMICS AND SOCIO-ECOLOGICAL VULNERABILITIES OF RECURRENT FLOODS IN MORIGAON DISTRICT, ASSAM

Abstract

Morigaon district is repeatedly affected by annual floods and severe riverbank erosion driven mainly by the Brahmaputra and its tributaries. Flooding disrupts livelihoods, damages crops and infrastructure, forces repeated displacement of riverine (char) communities and exacerbates public-health risks. This review synthesizes published studies, government reports, and situation updates to characterize flood drivers and spatio-temporal patterns in Morigaon, summarize impacts on people, economy and environment, evaluate past/ongoing mitigation and disaster-management responses, and identify gaps and pragmatic recommendations for building resilience locally. Key findings highlight the combined role of large river dynamics (Bankline shift and siltation), monsoon variability, and anthropogenic drivers (land-use change, inadequate embankments), while pointing to the urgent need for integrated, community-centred adaptation and improved early-warning and relocation planning.
