ANALISA SENSITIVITAS DURASI HUJAN PADA PERHITUNGAN DEBIT BANJIR DAS TENGGANG DAN SRINGIN
Abstract
This study was conducted to determine duration of rainfall that produces the maximum flood discharge for Tenggang and Sringin River. Calculation of flood discharge for Tenggang and Sringin River was carried out using a rainfall distribution pattern (hyetograph) for rainfall durations of 2 hours, 3 hours, 4 hours and 5 hours with the distribution of rainfall distribution referring to hourly rain data at Maritime Station. Results of analysis show that different distributions are produce different flood discharge values. For Tenggang and Sringin rivers, the maximum flood discharge value is obtained at a rain duration of 2 hours.
Keywords: flood discharge, rainfall duration, hyetograph
