Abstract: (33 Views) |
The Meghna River, a vital lifeline for Bangladesh, sustains ecosystems and livelihoods, facing increasing threats from a variety of natural and anthropogenic activities including rapid urbanization, advance agricultural production, industrialization, development of flood control devices, over exploitation, pollution, habitat degradation, and climate change. Thus, to achieve this aim, complete understanding of the River dynamics is an essential requirement for sustainable management. This paper examines the spatio-temporal distribution in the Meghna River Basin, particularly hydro-physico-chemical characteristics and bio resources. These included water color, depth, temperature, ph, dissolved oxygen, carbon dioxide levels, alkalinity, hardness, transparency, salinity, turbidity and TDS, conductivity. Two other groups of bio resources phytoplankton, zooplankton and bottom dwellers (benthic macro invertebrates) were also considered. Field surveys, laboratory analysis and satellite images were used for collection of data in relation to site selection. The analysis of this research work indicated that all the hydro-physico-chemical attributes and bio resources of the study area had spatial temporal coherency at congenial level. Furthermore, relations between these variables and their effect on the ecosystem were established and no anomally was found. The findings emphasize the critical state of the ecosystem amidst anthropogenic stressors and climate change, underscoring the need for effective conservation strategies to maintain the ecological balance and livelihood support of this vital river system. The presented data serves as a valuable resource for policymakers and conservationists aiming to protect and sustainably manage the river basin.
