1. Bendungan Panjang bendungan bagian bawah 395 m sesuai dengan jarak kontur pada elevasi 135m. Ketinggian Bendungan 35 m dari dasar sungai. Kemiringan sebelah kiri dan kanan berbeda dikarenakan menggunakan bendungan urugan tanah : Sebelah kiri = 1:2,2 Sebelah kanan = 1:2 Berdasarkan kemiringan tersebut diperoleh panjang bendungan bagian atas yaitu : 246,91 m Rumus untuk mencari lebar bendungan : 3,6 x H1/3 3. Berdasarkan rumus diatas didapatkan lebar bendungan bagian atas adalah 14 m, yang mana hasil tersebut diambil angka yang paling aman untuk bendungan urugan tanah. Untuk mendapatkan lebar bendungan bagian bawah, kemiringan yang digunakan untuk mendapatkan lebar bendungan yang bagian bawah adalah 1:0,34.

1.1 Tampak depan Bendungan

1.2 Tampak samping Bendungan

1.2 Tampilan 3 dimensi Bendungan

2. Cover DAM Panjang dan tinggi cover dam diambil dari bendungan yaitu: Panjang bendungan bagian bawah 99 m. Tinggi Bendungan 8,75 m. Kemiringan bendungan dipakai 1:2 sehingga diperoleh panjang bendungan yang bagian atasnya yaitu 64,2 m Lebar bendungan bagian bawah pun diambil dari dari lebar bendungan bagian bawah yaitu 10,5 m Kemiringan yang dipakai untuk lebar bendungan ini adalah 1:0,5. Berdasarkan kemiringan tersebut maka diperoleh lebar bendungan yang bagian atasnya yaitu 1,75.

2.1 Tampak Depan Cover dam.

2.2 Tampak samping Cover DAM.

2.3 Tampilan 3 dimensi cover DAM.

3. Diversion Tunnel Debit rencana = 2100 m3/s Bentuk Diversion Tunnel yang digunakan ialah persegi Panjang total diversion tunnel yaitu 890,34 Rumus yang di gunakan untuk mendapatkan dimensi diversion Tunnel : I = H/L A = DxH R = A/P V = 1/n x R2/3x I1/2 Q = A x V Untuk mendapatkan nilai H mengunakan metode trial and eror yang mana nilai debitnya harus lebih dari sama dengan debit rencana Tabel metode trial and eror :

Berdasarkan metode trial dan eror maka didapat nilai D dan Hnya : D = 60 m H = 56 m Gambar diversion Tunnel
