文摘
- •
Water–sediment interaction dominates groundwater evolution.
- •
A model of arsenic (As) influx and mobilization in Brahmaputra river basin is proposed.
- •
Geomorphology is hypothesized to be a major influencing factor for hydrogeochemistry.
- •
Geomorphic terrain dependent redox processes control the arsenic content.
