Gradient analysis of saline groundwater dynamics along spatial transects in the Chaco

摘要：

Introduction The transitional zone between the dry and the semi-humid Chaco is characterized by a high table of saline groundwater.Dryland salinity is commonly observed at the edges of seasonally inundated grasslands in landscape depressions without external runoff (so called water camps) surrounded by native drought deciduous thorn bush.So far,little information had been available on groundwater characteristics (depth and conductivity) as related to soil salinity.
