Climate change detection and attribution in the Ganga-Brahmaputra-Meghna river basins

Trends and persistence in precipitation in the Ganges, Brahmaputra and Meghna river basins

The Ganges, Brahmaputra and Meghna (GBM) river basins occupy about 1.75 x 10 km of the Himalayan region. More than half a billion people in Nepal, India, Bhutan and Bangladesh are directly or indirectly dependent on the water resources of the GBM rivers. These river basins are characterized by diversified climatic patterns. Analyses of trends and persistence in precipitation over these river ba...

Climate change and the world’s river basins: anticipating management options

Methods for climate change detection and attribution

Detection and attribution (D&A) have played a central role within the assessment of the human influence on climate and within IPCC’s reports. Detection involves the statistical demonstration that a change has happened within climatic observations. Attribution consists in assessing the respective contributions of one or several causes to some observed change. Both require the use of climate mode...

Future changes in hydro-climatic extremes in the Upper Indus, Ganges, and Brahmaputra River basins

Future hydrological extremes, such as floods and droughts, may pose serious threats for the livelihoods in the upstream domains of the Indus, Ganges, Brahmaputra. For this reason, the impacts of climate change on future hydrological extremes is investigated in these river basins. We use a fully-distributed cryospheric-hydrological model to simulate current and future hydrological fluxes and for...
