THE IMPACT OF RIVER BED SEDIMENTATION ON THE SUNDARBANS MANGROVE FOREST (BANGLADESH) WITH ITS EXCEPT

The current contribution focuses on conservation difficulties in Bangladesh's Sundarbans mangrove forest, which is a UNESCO World Heritage Site. The forest's declining number of Royal Bengal Tigers may be affected by current challenges to its environment. Furthermore, rising salt concentrations in the water are endangering plants and animals. Because the assessed Environmental Risk Index is quite low, the impact of dredging in the Passur River on the forest's so-called Outstanding Universal Value is negligible. The toxicity threshold will be set at 29%. The Sundarbans' salinity levels range from 54,025 dS/m to 69,152 dS/m for south western rivers, which is almost 50% higher than the average salinity value of 43,320 dS/m. There is a Strongly negative impact on soil, agriculture, fisheries, flora, and animals; all of this is harmful to the Sundarbans' Outstanding Universal Value. The Sundarbans natural setting and ecosystem are under substantial environmental stress, according to an examination of current physical, chemical, and biological processes that play a part in them.
