Perencanaan Sabo Dam Merapi PAC-3 Kali Pabelan
berlokasi di Desa Gondosuli Kabupaten Magelang Jawa tengah.
Kali Pabelan mempunyai luas DAS 4096 Km panjang alur
sungai utama 2136 Km kemiringan dasar sungai 0042.
Dengan kondisi tersebut potensi terjadinya erosi dan gerusan
pada Kali Pabelan sangat besar. Maka diperlukan adanya
bangunan Sabo Dam untuk menstabilkan sedimen yang mengalir
di Kali Pabelan.
Dalam hal ini pembahasan meliputi analisa hidrologi
analisa hidrolika dalam perencanaan dimensi Sabo Dam dan
kontrol kestabilan.
Dari hasil perhitungan diperoleh data teknis sebagai berikut
Elevasi muka air di atas pelimpah 92183
Elevasi pelimpah 92023
Tinggi jagaan 08 m
Tinggi keseluruhan Main Dam 1675 m
Kemiringan hulu 068
Kemiringan hilir 017
Dengan pembuatan Sabo Dam PAC- 3 Merapi Kali
Pabelan ini diharapkan bisa melandaikan kemiringan dasar
sungai dan mengurangi erosi yang terjadi.
ABSTRACT
Design of Sabo Dam Merapi PAC-3 Pabelan River
located in Gondosuli Village Magelang - Central Java. The
Catchment area of Pabelan River 4096 Km length of river
2136 Km and riverbed gradient 0042. With such condition the
Pabelan river has a large possibility of having erosion and
scouring. So need Sabo Dam building existence to stabilize
riverbed gradient and restrain sediment that flow at Pabelan
river.
In the case solution covers of hydrology analysis
hydrolic analysis the design Sabo Dam and stability control
construction.
From calculation result is got technical data as follows
Water flood elevation 92183
Overflow elevation 92023
Free board 08 m
Height of Main Dam 1675 m
The upstream slope 068
The downstream slope 017
With the design of Sabo Dam Merapi PAC-3 Kali
Pabelan is supposed can stabilize riverbed gradient and
decrease erosion that.
