Groundwater recharge and renewal in the Minle Piedmont Plain of the Heihe River Basin

Groundwater in the Quaternary aquifers is one of the major sources of water supply for domestic uses in the Minle Piedmont Plain,northwestern China. Groundwater flow and renewability are controlled by the buried faults. The present work discusses the groundwater recharge,renewal and effects of the buried faults on groundwater renewability by using the environmental isotopes. The results indicate that (1) the groundwater in the Minle Piedmont Plain is recharged from infiltration of river water an...
