A considerable length of the shore line on the upstream face of the reservoir bank, close to the reservoir embankment’s mitre, had slipped into the reservoir and this project was to stablilise the slippage and reinstate the shoreline profile.
The works involved the construction of a hardcore road to access the underwater area of the reservoir suffering from slippage and subsidence where the reservoir bank joined the main reservoir embankment close to the dam’s north mitre. The slippage area was excavated to a depth of 3.5m at the lower end with the cut infilled with rock armour which was subsequently re-covered with the excavated material. Once the rock armour had been covered and shaped to restore the shore-line profile, the temporary stone access road was removed.
