Abstract: The Jinan karstic spring groundwater basin is an important source for water supply to the city of Jinan. Spring water is also an attraction to tourists and citizens. Groundwater abstraction for water supply has caused drying springs at times. Four alternative groundwater development scenarios were designed,including the business as usual,increased recharge,decreased discharge,and combined scenarios. Numerical groundwater flow model was established to simulate the effects of these scenarios on gr...
