An integrated modeling system has been developed for analyzing the impact of climate change on snowmelt runoff in Kaidu Watershed, Northwest China.
The system couples Hadley Centre Coupled Model version 3 (HadCM3) outputs with Snowmelt Runoff Model (SRM).
The SRM was verified against observed discharge for outlet hydrological station of the watershed during the period from April to September in 2001 and generally performed well for Nash-Sutcliffe coefficient (EF) and water balance coefficient (RE).
The EF is approximately over 0.8, and the water balance error is lower than ± 10%, indicating reasonable prediction accuracy.
The Statistical Downscaling Model (SDSM) was used to downscale coarse outputs of HadCM3, and then the downscaled future climate data were used as inputs of the SRM.
Four scenarios were considered for analyzing the climate change impact on snowmelt flow in the Kaidu Watershed.
And the results indicated that watershed hydrology would alter under different climate change scenarios.
The stream flow in spring is likely to increase with the increased mean temperature; the discharge and peck flow in summer decrease with the decreased precipitation under Scenarios 1 and 2.
Moreover, the consideration of the change in cryosphere area would intensify the variability of stream flow under Scenarios 3 and 4.
The modeling results provide useful decision support for water resources management.
