Impact of climate and land-use changes on the water and sediment dynamics of the Tokoro River Basin, Japan

•The impacts of climate and land-use changes on water and sediment dynamics were assessed for a river basin in northern Japan.•Severe depopulation is currently undergoing in rural areas of Japan.•Climate change decreased both discharge and SS loads due to an increase in evapotranspiration.•Land-use...

Summary:•The impacts of climate and land-use changes on water and sediment dynamics were assessed for a river basin in northern Japan.•Severe depopulation is currently undergoing in rural areas of Japan.•Climate change decreased both discharge and SS loads due to an increase in evapotranspiration.•Land-use change decreased sediment yield but accelerated channel erosion, resulting in little changes in suspended sediment loads.•Combined climate and land-use changes substantially decreased suspended sediment loads due to a decrease in discharge and sediment yield.
