Lumami, Feb. 11 -- Nagaland University Researchers have completed a pioneering GIS-based hydrological study that scientifically examines how geo-ecological conditions and human activities influence runoff and river flow in the North Eastern Himalayan hill region, an area long marked by data gaps and global scientific debate.

According to a press release, the research addresses a critical and contested question in Himalayan science - the true hydrological impact of land use change on river discharge, floods and environmental degradation.

Beyond advancing scientific understanding, the study proposes a practical four-zone runoff classification-low, moderate, high and very high runoff zones-to support water resource planning, flood mitigati...
