ANALISIS KARAKTERISTIK SEDIMENTASI DI WADUK PLTA BAKARU
Abstract: The aims of the
research are to identify the characteristics of sedimentation process, to
identify the sources of sedimentation and to prevent sedimentation process in
Bakaru Dam.Data collection were carried out through surveys and interviews. The
surveying methods were applied to identify bio-physical characteristics of the
study area by implementing measurements and sampling for elevation, water flow
debit, water ground depth, river profile, and water depth in the dam. Data were
then analyzed by utilizing cross-tabulation method. The data gained were later
used in formulating some recommendations regarding some problems found in the
field.The results show that the characteristics of sedimentation in Bakaru Dam
was bedload type occurring from the river bank to Bakaru Dam which was
dominated by sand (87%). For the exception, in sub-village Salumada, the sand
content was between 35% to 56% while the source of sedimentation in Bakaru Dam
was derived from the river ground and were existed in Mamasa Hulu Bae River,
Sapai River, Sumarorong River, Tabone River, Batuapang river, and other rivers.
The method in preventing erosion and sedimentation were by forming a Management
Board to formulate policies, standards, and criterion of success as well as
monitoring guidelines and evaluation, to formulate Mamasa Watershed management,
to conduct the works in the field according to the plans/standards determined
by involving the government, State Electricity Sources, enterprises, and the communities.
