Tabel 2.12 Hubungan Lebar Tanggul dan Jenis Saluran Catatan Debit 1a Data cukup (20 tahun atau lebih)

Metode

Parameter Perencanaan

Analisa distribusi

Debit rata-rata tengah

frekuensi normal

bulanan dengan kemungkinan tak terpenuhi 20%

1b Data terbatas

Analisis frekuensi rangkaian

seperti pada 1a dengan

debit dihubungkan dengan

ketelitian kurang dari itu

rangkaian curah hujan yang mencakup waktu lebih lama. 2 Data minimal atau tidak ada

a. Model simulasi

seperti pada 1b dengan

perimbangan air dari Dr.

ketelitian kurang dari itu

Mock atau metode serupa lainnya. Curah hujan di daerah aliran sungai, evapotranspirasi, vegetasi, tanah, & karakteristik geologis daerah aliran sebagai data masukan b. Perbandingan dengan daerah aliran sungai di dekatnya 3 Data tidak ada

Metode kapasitas saluran

seperti pada 1b dengan ketelitian kurang dari itu

Aliran rendah dihitung dari muka air rendah, potongan melintang sungai & kemiringan yang sudah diketahui. Metode tidak tepat: hanya sebagai cek. zSumber : KP-01, Tahun 1986
