Understanding human-water nexus in a floodplain district of the Brahmaputra Valley, India: An integration of socio-hydrological and rural hydrological approaches.

The present study delves into the complex human-water relationships that have a significant impact on the concerned socio-cultural practices and economic livelihoods. The primary objective of this research is to explore and comprehend the dynamic relationships between local communities and water systems in the villages of Nagaon district, situated in the floodplain of the Brahmaputra Valley, India. By integrating socio-hydrology and rural hydrology, the study seeks to gain a holistic understanding of water usage patterns, land management practices, and human adjustments to the district's diverse hydrological environment.

Micro-spatial flood risk assessment in Nagaon district, Assam (India) using GIS-based multi-criteria decision analysis (MCDA) and analytical hierarchy process (AHP).

Nagaon is one of the highly flood-prone districts of Assam, India that recurrently experiences devastating floods resulting in the loss of lives and property and wreaking havoc on the district's socioeconomic infrastructure. Identification and mapping of spatial patterns of flood hazards, flood vulnerability, and flood risk zones (FRZs) of the district are, therefore, crucial for flood management and mitigation. The present study, therefore, attempts to delineate the FRZs of more than 930 villages in the Nagaon district by integrating the flood hazard and vulnerability layers in the geospatial environment using the multi-criteria decision analysis and analytical hierarchy process techniques.

Delineation of groundwater potential zones at micro-spatial units of Nagaon district in Assam, India, using GIS-based MCDA and AHP techniques.

Groundwater is one of the most precious natural resources in the densely populated regions of the world. The ever increasing population in the developing countries like India and the concurrent growth of industrial and urban centres along with modern agricultural systems have caused tremendous pressure on groundwater. In the present day context of groundwater depletion and degradation, it is necessary to identify and map the groundwater potential zones (GWPZs) of an area to manage and utilize them sustainably.
