Abstract

Embankment schemes are often built to contain river flooding on alluvial flood plains. These flood plains invariably contain permeable fluvial deposits and an interaction between the river flood and the groundwater system may result in high groundwater pressures evolving inside the area protected by an embankment. This may result in either seepage of water to the ground surface causing flooding or instability of the ground due to high porewater pressures. The purpose of this study has been to investigate this phenomenon and to examine ways in which the reaction of the groundwater system to an imposed river flood, contained behind an embankment, may be predicted.
