Abstract

Material dredged from the Delaware River is being stored on land in areas surrounded by man-made dikes. In the past, the height of these dikes had been increased in order to provide the needed additional storage space. However, existing land configuration and the high water table in the storage areas, together with the high water content and low strength of the stored dredged materials prohibit further increases of the dike height. A system of interconnected drainage trenches, excavated inside these areas and discharging into the river, was used to lower both the water table and the water content of the dredged materials to a degree that they could be used in the construction of new and higher dikes, thus providing the additional storage space needed.

The Creation of Additional Space for the Storage of Dredged Materials - A Case History

Material dredged from the Delaware River is being stored on land in areas surrounded by man-made dikes. In the past, the height of these dikes had been increased in order to provide the needed additional storage space. However, existing land configuration and the high water table in the storage areas, together with the high water content and low strength of the stored dredged materials prohibit further increases of the dike height.
