3.7 Perhitungan Intensitas Curah Hujan

Analisis intensitas curah hujan menggunakan rumus yang diberikan oleh DR. Mononobe yaitu:I = Dimana:I = Intensitas Curah Hujan (mm/jam)R24 = Curah hujan maksimum dalam 1 hari (mm)t= Lamanya Curah Hujan (jam) Perhitungan :Pada perulangan 2 tahun periode ulang 1 jam.I = = 18,72 mm/jam

Untuk hasil perhitungan selanjutnya dapat dilihat pada tabel.
