Risk and Stability Evaluation of Klego Dam, Boyolali, Indonesia
Klego Dam was constructed in the 1990s and has been operated since 1993. Its main function is to supply Irrigation water of 13.53 km2. It is located right at the boundary between Bengawan Solo Watershed and Jratunseluna Watershed. Previously, the dam was managed by BBWS Bengawan Solo. In the 2010s, the dam’s management is relinquished to Pemali Juana River Basin Authority. This management’s change contributes to some discontinuity in the dam’s operation and maintenance, which contributes further to the loss of some important historical data and information of the dam. This unfavorable situation for proper operation and maintenance of the dam is further aggravated by the publication of Indonesian’s new ground speed (earthquake) map for seismic design. It is, therefore, urgent to evaluate the stability and safety of Klego Dam with the new earthquake map even under limited available data and information. The paper presents the evaluation on the status of the dam’s safety considering the seepage and slope stability. It uses Geostudio software to evaluate stability of the dam under various conditions. It also performed seepage analysis uses limited Piezometers’ records. The analysis shows that the safety of Klego Dam is barely sufficient. However the dam needs some rehabilitation on its embankments, dam’s crest, and its instrumentations as well as the proper implementation of Maintenance and Operation procedures. The availability on the SOP and its implementation will reduce the risk of dam’s failure.
