Evaluation of Riverbank Hydraulic Conductivity: Implications for Groundwater Recharge

Abstract

This study highlights the relationship between the hy draulic conductivity (K) of riverbank deposits and groundwater recharge in an area adjacent to a Chalk river in Hertfordshire, United Kingdom. Three locations were mapped out for Insitupermeability measurements based on geological map data indicating cha nges in superficial deposits along the river Mimram. The study area is predominated by Cretaceous Chalk and overlain by drift deposit such as glacial till and buried channel deposits which include glaciofluvial gravels,
