Research Abstract	This study evaluated the impacts of increased irrigation agriculture on surface and groundwater availability in middle and upper Yellow River Basin in China. To this end, we developed an integrated modeling framework consisting of economic and MIKE SHE hydrologic models. Developed model was calibrated using streamflow and groundwater table data during 1994-1995, and then validated using the data during 1996-1997. Streamflow and groundwater table simulated by the MIKE SHE model matched historical observations reasonably well. Our results indicate that further expansion of irrigation agriculture have serious impacts on the amounts of surface and groundwater in the region. Adopting better and more efficient irrigation systems may be one of the most cost-effective measures to conserve surface and groundwater resources in the basin.
