This report describes the results of theoretical analytical and field studies related to the problems of seepage and lining of the enlarged Ismailia Canal, Egypt. Direct measurements of seepage from the canal are reviewed and analyzed. Future seepage is estimated by using idealized models, that however ignore the possible existence of natural sealing by Nile silt. To investigate this hypothesis the HRS In Vibro-corer was operated on the canal - the first application in freshwater conditions. Corers were retrieved from the canal bed in an 8km reach with moderate success. The efficiency of the corer is evaluated in detail from the data obtained. The cores were prepared and analyzed at the Delta Barrage Laboratory. The results are described herein with their implications on the sealing phenomenon. Suggestions for extending the present studies using direct seepage measurements are explained in order to arrive at a logical decision whether to proceed with lining the canal. The work is part of a continuing research co-operation with the Hydraulics and Sediment research Institute, Arab Republic of Egypt.
