A New Attempt to Evaluate the Renewable Capacity of A Typical Karst Groundwater System by Using 13C and 14C——A Case Study of Karst Groundwater in Pingyi-Feixian County, Shandong Province

摘要

Objective The renewable capacity is an important attribute of groundwater resources.Most previous studies have focused on the porous aquifer systems by the measurement and analysis of isotopes deuterium(D),oxygen-18(^(18)O),tritium(~3H),and carbon-14(^(14)C)
