The central route of the South–North Water Transfer Project (CTP) is designed to divert approximately 9.5 billion m 3 of water per year from the Han River, a major tributary of the Yangtze River, to the Hai River basin in the north China. The main purpose of this study is to assess the impact of CTP on groundwater table in the Hai River basin. Our study features a large‐scale distributed hydrological model that couples a physically based groundwater module, which is sub‐basin‐based, with a conceptual surface water module, which is grid‐based. There are several grids in each sub‐basin and water exchange among grid that are considered. Our model couples surface water module and groundwater module and calculates human water use at the same time. The simulation results indicate that even with the water supply by CTP, the groundwater table will continue to decline in the Hai River basin. However, the CTP water can evidently reduce the decline rate, helping alleviate groundwater overexploitation in Hai River region. Copyright © 2013 John Wiley & Sons, Ltd.
