APLIKASI METODE AMBANG BERTINGKAT UNTUK ANALISIS POTENSI BANJIR: STUDI PENDAHULUAN PADA 15 DAS DI JAWA TIMUR
Abstract: This research deals
with identification of potential flood discharge from 15 watersheds located in
Eastern Part of East Java Province. Recorded times series of daily discharges
data are used as main input for the analysis. The discharge data for each
watershed are rangked from lowest to high value. Then, the value of discharge
correspond to quantile 90% (Q90) is calculated and determined as the threshold
level for each watershed. In this case, discharge data more than > Q90 value
is categorized as flood events. Then, the frequency of flood events are
calculated based on monthly or annual time interval. Furthermore, spatial
distribution of flood events are visualized by comparing the frekuency of flood
events amongs the watersheds. Finally, thematics maps corresponde to waterheds
properties, frequency of flood events, and rainfall event are presented.
