Flood known as disaster that have the most significant impact in the world. More than half of food stock in Asia was damaged during the flood disaster. Flood categorized as geo-hydrological disaster which cause by complex relation between physical, natural, artificial, and social environment that include the characteristic, function, organization, development, and human perception in associated with geological and hydrological process. The increase of population led to high urbanization, developed area, and reducing catchment area thereby increase the surface runoff and flood. This reasearch look at the surface runoff as a system that can be influenced by intervention of increasing taxes in order to control landuse change. The purpose of this study is to prove the conceptual model that flood is not only caused by the physical but also social, economy, technology, and institution components. The generated flow was calculated using hydrogeological model based on physical process and then calibration was done to get the sensitive parameters. There are two senstive parameter found in the model namely runoff curve number and surface runoff lag time. Relational Tree Analysis used to obtain component that build the system then made into System Interrelationship Model. Interventions carried out on River, Trees and Shrub, River Authority, and Taxes components. Among the interventions, Tree and shrub is the most sensitive components that can be developed to achieve the purpose of controlling surface runoff in the watershed.
