Researchers used a computer model called MODFLOW to study how groundwater flows in the Daduma River area of the Qilian Mountains. They considered the area's complex terrain and changing water levels, creating two models with different groundwater thickness. The models were calibrated using existing data. Results showed that one model had 2.76% of mountain recharge from precipitation, while the other had 0.103%. Base flow made up 79.307% and 77.570% of total water in the models, respectively. Evaporation and precipitation recharge accounted for 36% and 67% of the water. These simulations help understand how water moves in rocky, high-altitude mountain areas with limited data, offering insights for future research.
