PERANCANGAN WADUK MUNDINGAN DI KOTA SEMARANG
ABSTRACT: Flood in the
Semarang City occur every year in the rainy season, drought and water shortages
in the dry season. It has been built Jatibarang Reservoir and upstream there is
a potential reservoir that could add to the raw water supply and flood control.
The analysis used in planning reservoir that is the analysis of hydrology and
hydraulics. Hydrological analysis using methods Soil Conservation Service Unit
Hydrograph Synthetic (SCS) and Unit Hydrograph Synthetic of GAMA I. Q100 flood
discharge plan with 165 mm of rain, the result of a method SCS unit hydrograph
assisted HEC-HMS program amounting to 442 m3 / sec while the HSS GAMA I method
with 218 mm of rain discharge plan generated at 359.02 m3 / sec. Flood
discharge calculation used is a method SCS. PMF flood resulting from rainfall
of 2408.7 mm deep as 677 m3 / sec. With the design of flushing water of 1.7 m3
/ sec then storage volume up to 20,000,000 m3 and a storage volume of sediment
up to 1,000,000 m3. With the reservoir can reduce flooding 100-year period by
77% from 442.9 m3 / sec to be 97.1 m3 / sec, and reduces the PMF discharge of
66% of 2408.7 m3 / sec to be 814.2 m3 / sec and reservoirs totaling 38 million
m3. Dam 34 m high, dam crest 10 m wide, rock fill zone embankment type and
spillway crest width of 20 m
