Abstract

Different land covers affect water quality through interaction at root microsites during various phases of nutrient uptake. The litter layer and its decomposition, microbial interactions, and physico-mechanical all have roles with soil influencing water uptake directly or indirectly. However, the role of vegetation on water is dependent on the scale of space and time. Water samples from creeks and seepages were collected from mountainous catchments of varied land cover in southeastern Bangladesh to comprehend the land cover effect using paired watershed methods. The water sample analysis for common anions and cations found that shifting cultivated catchments contained higher 1 and 2 and lower 3, Na+, K+ and TDS compared to natural vegetation areas. The cations of water sample showed a regular trend than anions with land cover change. University of Chittagong
