The precipitation recharge coefficient (PRC) is an important parameter for regional water resource evaluations and groundwater numerical simulations. This parameter has evident seasonal variations due to seasonal differences of climatic and vegetation, especially in cold arid regions. While the annual mean value and spatial variability of PRC are reported commonly, fewer studies have focused on seasonal...
Understanding the pattern of regional groundwater circulation is essential for sustainable management of groundwater resources and ecosystems protection. A large-scale basin may develop nested groundwater flow systems including local, intermediate and regional flow systems. Hydrogeochemical tracing may be an effective methodology to identify different groundwater flow systems, considering its routine...
