EVALUASI SISTEM DRAINASE DALAM UPAYA PENANGGULANGAN BANJIR (STUDI KASUS KELURAHAN HONIPOPU KOTA AMBON)

Urban drainage systems serve the disposal of excess water in a city by draining it through the soil surface or passing below the ground surface, to be discharged into rivers, lakes and the sea. The excess water can be in the form of rainwater, domestic wastewater and industrial wastewater. Therefore, in order to prevent flooding in urban areas, an urban drainage system must be integrated with sanitation, garbage, city flood control and also the state of the surrounding area. The objectives of this research are 1) to identify the drainage system that always causes flooding in Honipopu Village, Ambon City; 2) Determine the direction of the right drainage system in an effort to overcome flooding in Honipopu Village, Ambon City. Data collection methods used in this study include: observation, interview techniques, agency surveys, and documentation. Analysis of the data used is an analysis of the basic physical conditions of the research area, including slope, hydrology, nalysis of the data used is an analysis of the basic physical conditions of the research area, including slope, hydrology, rainfall conditions and land use. Drainage conditions in Honipopu Village are poor due to very high sedimentation and waste water discharge causing drainage to become shallow and also to inadequate drainage system. The direction of the drainage system in an effort to cope with flooding in the Honipopu village is the rehabilitation and normalization of drainage strategies.
