PENENTUAN KAPASITAS DAN TINGGI MERCU EMBUNG WONOBOYO UNTUK MEMENUHI KEBUTUHAN AIR DI DESA CEMORO
ABSTRACT: Cemoro village is
located in Wonoboyo Sub district , Temanggung District, Central Java Province
with the area is 778.9 ha. There are 2.355 people in Cemoro village (1.187 male
and 1.168 female). Most of the residents work as plantation farmers. In the dry
season, water discharge in the Lingseng River becomes very small, so it can not
meet the demand for drinking water and the irrigation needs. Based on water
balance, there is a deficit around 27.140,23 m3, that certainly reduce
productivity in both agriculture and social welfare. Therefore, the hydraulic
structure is needed. To overcome the water deficit one of the efforts is by
constructing a small dam. The design minimum capacity of the small dam is
27.140,23 m3. The gross capacity of the storage is 30.653,45 m3 which take into
account of sediment storage. Based on correlation graph of elevation, volume
storage, and area storage, the head elevation of spillway is +1.542 m. The head
elevation of small dam is +1.545,50 m which take into account of flood water
level and freeboard. By the presence of small dam, it is expected to cover the
water deficit so it can increase the water supply for drinking water and
irrigation of horticulture farm.
