Based on analyses of physiographic, meteorological, hydrological, and geological conditions, as well as groundwater resources development and utilization in the valley terrace of the Shichuan River, in Fuping County, a three-dimensional hydrogeological structure model was built, and the feasibility of the establishment of the Shichuan River groundwater reservoir was demonstrated. The storage capability of the groundwater reservoir was about 4. 95×10⁸ m³. The variation of groundwater level ten years after the implementation of artificial recharge with the amount of 0. 52×10⁸ m³ per year under different precipitation and pumping conditions was predicted through groundwater numerical simulation with the Visual MODFLOW software. The results show that the groundwater level of the reservoir would rise considerably, with the water levels in most parts of the reservoir area approximating the level in 1959, indicating that the local water demand could be basically satisfied.
