Abstract

The main issue is that the watershed in Ciliman floods during the rainy season. Watershed Flood Ciliman carries sediment, sludge, rocks, and vegetation from either bank of the river that was uprooted as the flood came downstream. Many locations are prone to landslides, which encompass the entire river flow. Flood mitigation was carried out entirely hydraulically. The Cibinuangeun River Diversion and River Normalization Cilemer has been completed. One option is the notion of ecological hydraulics, which employs bioengineering approaches. The purpose of this study is to use the Analisys Hierarchy Process (AHP) to make decisions about which priority bio-engineering methods can be used to manage floods in the Ciliman Watershed in Banten Province. This study used a mixed-methods approach (quantitative with a less dominating qualitative component). The analysis hierarchy process (AHP) was used to choose priority bio-engineering methods for flood management in the Ciliman Watershed in Banten Province. This is shown from the weighting results for bush cushions reaching 0.467, while the weight for staked woody plant stem cuttings is only 0.332 and the weight for biopore infiltration holes is only 0.201.
