dam break is overtopping and piping. Dam break due to overtopping occurs because of the
overflow water in the reservoir through the body of the dam. In the other hand, the collapse
of the dam due to piping can not be ascertained by the initial collapse location due to scour
caused by seepage occuring inside the dam’s body. Therefore, of the dam break it is
necessary to analyze the collapse of the dam to know the disaster and affected areas caused
by dam break.
The purpose of this research is analyzing the alternative in the various scenario of
the dam break using HEC-RAS program version 5.0.3 developed by Hydrolic Engineering
Center. The program allows to perform simulations of flooding due to the dam break with
the 2D model. In this study, it is conducted a simulation of the overtopping due to the dam
break. In addition, to the overtopping the flood in the dam break due to the piping was also
simulated.
Banyukuwung Dam is a homogeneous dam built at 1996. The downstream of the
Banyukuwung Dam is located in Rembang Bay (Java Sea). Banyukuwung Dam break may
occur due to the overtopping and piping. Simulations conducted with program HEC-RAS
5.0.3, sugested that a collapse due to the overtopping is a cause of Banyukuwung Dam break
showing the greatest impact with a condition of design floods of 0,5PMF, a peak discharge
Qinflow 239,9 m³/sec and area puddle 1907,475 ha with high maximum inundation of 7,95
m. As a result of the Banyukuwung Dam break, there are 23 villages in the downstream of
the Banyukuwung Dam are exposed to inundation with a number of population exposed to
the risk is 17015 inhabitants. The distance of the Banyukuwung Dam to the downstream is
only 9 km, it can be concluded that Banyukuwung Dam is classified as a dam with a danger
level of 4 which means a very high danger level.</description><date>2018-11-08</date><type>Thesis:Thesis</type><type>PeerReview:NonPeerReviewed</type><identifier> Torimtubun, Angelina Tutulenan (2018) Analisa Banjir Akibat Keruntuhan Bendungan Banyukuwung dengan Menggunakan HEC-RAS.
