英文摘要	Study region: Upper Rio Grande, Colorado and New Mexico, USA. Study focus: Climate change is predicted to further limit the water availability of the arid southwestern U.S. We use the snowmelt runoff model to evaluate impacts of climate change on snow covered area (SCA), streamflow timing and runoff volume. Simulations investigate four future conditions using models downscaled to existing climate stations. Twenty-four subbasins of the Upper Rio Grande containing appreciable snowmelt and a long-term gauging station are simulated. New hydrological insights for the region: Future annual volume is 193-204 million m(3) more to 448-476 million m(3) less than the pre-climate change value of 2688 million m3. There is disparity between increased volume in wetter simulations (+7%) and decreased volume (-18%) in drier simulations. SCA on 1 April reduced by approximately 50% in all but the warmer/wetter climate. Peak flow is 14-24 days early in the future climates. Among the 24 subbasins there is considerable range in mean melt season SCA (-40% to -100%), total volume change (-30% to +57%) and runoff timing advancement indicating that climate change is best evaluated at the subbasin scale. Daily hydrographs show higher streamflow in March and April, but less from mid-May until the end of the water year. The large decrease in volume in May, June and July will compound water management challenges in the region. Published by Elsevier B.V.
