Abstract: The main problem is the watershed Ciliman flooding when the rainy season comes. Watershed Flood Ciliman carry sediment mud, rocks and vegetation either side of the river who participated uprooted when the flood came toward downstream. Many areas prone to landslides that cover a total river flow. Flood mitigation has been done with pure hydraulic method. Making cibinuangeun river diversion and river normalization cilemer has been done. One alternativeis the concept of ecological hydraulic using bio-engineering methods. This study aims to apply Analisys Hierarchy Process (AHP) for decision making in the selection of priority bio-engineering methods that can be applied in flood control at Ciliman Watershed Banten Province. The method used in this study is a mixed methods (quantitative less dominant qualitative). Analysis conducted the analisys hierarchy process (AHP) to determine the selection of priority bio-engineering methods that can be applied to control flooding Ciliman Watershed Banten Province. The primary data used were interviews and questionnaires from 9expert respondents. Secondary data used is Ciliman Watershed maps, map making longitudinal cross section of the river, watershed Ciliman geological maps, soil type maps Ciliman watershed, water resources watershed map Ciliman, Lebak in numbers 2013, the District Pandegelang in numbers 2013 and the study of literature.
