PERENCANAAN BENDUNGAN BENDO PONOROGO
ABSTRACT: A number of
regionsin Ponorogo, East Java Provincehas a variety of water resource
managementissues, includingfloodsduring the rainy seasonandwater shortagesduring
the dry season. To overcome these problems then we planned Bendo dam.Methods of
planning begins with determining the position of the location, hydrology and
hydraulics which finally obtained information to determine the design of the
dam. Bendo dam is planned to use dependable discharge with a probability of
80%. Water requirement value to fulfill the needs of irrigation water is 2.19
liters/sec/hectare and the water requirement is 823.7 liter/sec. We used HSS
Nakayasu Flood discharge method with 1,000-year return period amounted to
676.37 m3 / sec. Bendo dam is also planned as a hydropower that produces
1.697,953 Kw hydroelectric power. Bendo dam is planned using Rockfill dam type
with a core of impermeable clay with a slope of 1: 2,5 in the upstream and 1:
1,75 in the downstream. The peak height is 78,5 m, the width of the peak is 13
m, and the full length of the dam is 354,02 m with 50-years lifetime design.
