Analysis of precipitation and recharge of aquifers in Tota and Ibagué (Colombia) from stable isotopes (18O and 2H)

Identifying the hydraulic connection between the area of recharge and the area of discharge in aquifers is only possible by using tracers; the 18O and 2H isotopes have proven to be good tracers to determine such hydraulic connection. It is assumed that in Ibagué and Lake Tota the recharge of the aqu...
