| dc.description.abstract | Some areas in Ponorogo Regency, East Java Province have a natural
resource management problem, including flooding during the rainy season and
lack of clean water when the dry season arrives. To overcome these
problems, Bendo Dam is planned. The planning method begins by determining
the location, hydrology, and hydraulic location, which finally obtained
information to determine the design of the dam. From the results of the study we
found the dimensions of the dam body based on Q1000th, including the dam
height of 88 m, the elevation of the dam peak El.224.00, the length of the dam
peak 15 m. The building material of the dam body has physical and mechanical
properties that meet the existing criteria. discharge is 649.16 m3 / sec to get the
magnitude of the river flow discharge using the Nakayasu HSS method. So that
the total dam reservoir is 43,599 x 106 m3. Results Upstream slope stability after
the dam has been built The normal state is 2.337> 1.5 (safe) and in an
earthquake situation is 1.772> 1.1 (safe). The results of the analysis of the
stability of seepage are as follows: 0.0094 m3 / sec < 0.05% <21799.5 m3 / sec
(safe).
