英文摘要	Mountain block recharge (MBR), an important water resource, is a widespread process that recharges lowland aquifers. However, little is known about MBR due to the limited climatic and geologic data in mountainous regions such as the northern central foothills of Tianshan. Here, we present an approach to quantify MBR through the combination of water balance calculations and numerical modeling. MBR calculated from the water balance in the data-limited Tianshan Mountains is employed as a fluid-flux boundary condition in the numerical model of the plain. To verify the performance of the model, mean absolute error and root mean square error were used. Results show that the volume of water that is recharging the aquifer via MBR is 107.29 million m~3/yr, accounting for 2.2% of the total precipitation that falls in the mountains. Additionally, 53.3% of that precipitation enters the plain aquifer via runoff, totaling 2,652.68 million m~3/yr. The lower volume of MBR is attributed to a major range-bounding anticline with apparent low permeability in the Tianshan Mountains. Through numerical modeling of groundwater, MBR coming from bedrock was found to be significant, accounting for 14% of total aquifer recharge in the plain, only after the portion of runoff seepage. This research contributes to a deeper understanding of MBR, and may provide instructions for estimating groundwater recharge in arid and semi-arid areas.
