It has a fracture system providing the transmissivity and a low unconfined storage coefficient of up to 2%.<\/jats:p>\n          <jats:p>Conceptualization of regional aquifers is carried out to support regional modelling studies. In such studies, observation well piezometry is of primary importance in understanding the hydrogeology of an area. While flow gauging provides an understanding of surface water responses, observation wells provide spatial detail of the groundwater response within each catchment.<\/jats:p>\n          <jats:p>During review of the Environment Agency's East Kent Chalk groundwater model, geomorphological and hydrogeological data were used to characterize the area in two zones; the primary and secondary dip slopes, in the first part of this paper.<\/jats:p>\n          <jats:p>The second part of the paper considers quality control and classification of the piezometry responses with respect to permanent and ephemeral Chalk streams and the Chalk escarpment.<\/jats:p>\n          <jats:p>The third part of the paper looks at an analysis of lag between rainfall and recharge to the water table.
