| description | Bandung is one of the areas prone to flood disasters in Indonesia. The areas frequently affected by flooding are located around the Cikapundung Watershed. Floods are triggered by several factors, namely: rainfall, changes in land use, as well as geological and morphological conditions. The aim of this research is to analyze rainfall in the Cikapundung watershed to see whether there is an increase in extreme rainfall from 1977- 2022. The method used in this research is first to test the homogeneity of rainfall over 45 years. Next, the extreme rainfall indices and the trend of each wet extreme rainfall indices were calculated using the Mann-Kendall test. The research results show that statistically, of the 20 indices analyzed, only one indices experienced a significant downward trend, namely the Rx5day indices at Kayu Ambon station. Other indices show a p-value of more than 0.05, which means statistically there is no trend, either an upward trend or a downward trend. |
