In addition, serious seepage problems occurred with the commissioning of the scheme. The paper describes in detail, the events of slides & seepage problems faced and the remedial measures adopted to counteract them. The data observed on the instruments installed to keep a vigil on the performance of the structure has also been analysed and discussed.
