The Rupsha River is a significant waterway in the southwestern region of Bangladesh. It is a distributary of the Ganges, which is locally known as the Padma when it enters Bangladesh. The river merges with the Bhairab and Pasur Rivers before flowing into the Bay of Bengal. Spanning a notable distance, the river passes through Khulna district, one of the country's industrial hubs. The Rupsha River is an essential source for the livelihood of the local populations, providing routes for inland water transport and fishing. The riverbanks host a diverse array of activities including the bustling Port of Mongla, the second-largest seaport in Bangladesh, situated near the river's confluence with the Pasur. The surrounding landscapes feature a mix of rural settings with lush greenery and urban industrial development. The Rupsha Bridge, a significant landmark, spans the river and facilitates regional connectivity. This river is also a vital water source for the Sundarbans, the world's largest mangrove forest, which lies to the south of the Rupsha. The river's ecosystem supports a variety of fish species and birds, making it a point of interest for both economic and ecological reasons.
