From the analyses above, it was recommended that construction of the new and improved embankment adhere strictly to the fol-lowing construction methods:
(a) Width from the side of the flow channel to the edge of the embankment shoulder should be at least 12 m.
(b) Rock toe with its extended berm to be constructed at the base of existing embankment.
(c) Hydraulic sand-filling process to be suspended every 12 hours to allow drop of phreatic surface so that the FOS against em-bankment slope failure can be increased.
