                  The present study combines  the exposure and

                classified into five categories (very high, high, moderate,   increases toward the surrounding hills, both the elevation
                low, and very low) based on the risk level. It is inferred   and flood risk decrease, contributing to the lower flood

                388 and 476 Barak River floodplain villages are at very
