Formation of the shallow groundwater in the Northern Henan Plain based on isotope ananlyses

Precision of assessment of groundwater resources is greatly affected by many indeterminacy factors in items of charge and discharge of a groundwater system.Increase of the precision of assessment of groundwater resources is of important significance to hydrogeologists.This paper introduced three means to enhance the precision of assessment of groundwater resources examining the replenishment of the shallow groundwater.(1) Combination of elements and change in isotope contents in groundwater can ...
