India’s massive civil engineering project, the National River Linking Project (NRLP), will not only reduce inflow of the northern rivers, but also significantly reduce the sediments deposited by the rivers in deltas, a study shows. Fertile deltas will be under threat, with coastal erosion expected to threaten the land and livelihoods of local economies that support 160 million people. Four researchers from the University of Colorado sought to fill critical knowledge gaps in the understanding of the impact of the project: reduction in river discharge due to extensive canal works, and silt trapping in newer reservoirs and barrages. The study was published earlier this year in the journal Elementa: Science of the Anthropocene.
