Abstract: This paper is concerned with the control of seepage problems which develop in existing dams. It is prefaced with a discussion of attitudes and experiences that have evolved over the last twenty years since the Dam Safety Law of 1972. Following this is a discussion of the evidence of developing problems, then causative factors and control methods - distinguishing drainage from cutoff measures. Emphasis is placed on remediation techniques which have developed in the last twenty years, particularly the use of geotextiles and slurry trench procedures.
