Abstract

The unique features of flow and transport in the chalk aquitard in the Negev desert were first
documented on a regional scale by the monitoring of 23 wells which penetrate the chalk
across the central and northern Negev. We suggested that water and solutes shortcut
through the low-permeability matrix of the vadose chalk via hctures and joints, escaping
much of the land surface exposure to evapotranspiration. This conclusion was based on
observed seasonal fluctuations of water level in these wells and the chemical and isotopic
