Soil pollution in Guwahati city, Assam, India has become a major concern since the last few decades. To study the impact of automobile and industrial emission, distribution patterns of 16 different polycyclic aromatic hydrocarbons (PAHs) and eight heavy metals were investigated in the soil samples collected from 15 different sites. Higher concentration of total PAHs and heavy metals was found in the industrial areas compared to the high traffic areas. Differences in the pollutants observed between the polluted and nonpolluted sites, endorse that anthropogenic activities are the major cause of soil contamination.Keywords

Water resources management of the transboundary Brahmaputra river basin is challenging due to limited hydro-climatic information beyond the national boundary. The present study uses soil and water assessment tool (SWAT) to evaluate the likely impact on hydrology, due to water diversion activity. Adopting several scenarios of water diversion, simulation results of the SWAT hydrological model show a significant impact on streamflow along the downstream of a hypothetical reservoir at the Indo-China border. The monthly discharge at ‘Bhomoraguri’ reduces up to 15.77% against only 10% withdrawal. Besides, diversion would lead to a change in sediment discharge of the Brahmaputra.Keywords
