Abstract

Rapid population growth will never stop as sources of problems that occur in almost all major cities in Indonesia. Local government in handling and anticipating the growth population tend to be less prepared, causing the city to become increasingly chaotic. Reduced and lost of parks and green open area into building area will effect to the hydrological conditions, especially floods event in these area. In addition, the trends and variability of climate change like temperature and rainfall, especially the extream rainfall frequency that occured in Bandar Lampung city. The aim of research are to identify the maximum flood areas due to maximum rainfall with return periods of 2, 5, 10, 20, and 30 years; to assess the maximum capacity of river and drainage channels to maximum flooding; to assess the volume and duration of overflow event. The maximum rainfall calculation has calculated with frequency analysis, the maximum flood has done with rational modification method. Calculation of river capacity or drainage channel was conducted with slope area method and manning formula. Calculation of volume and duration of flooding was used flood hydrograp analysis. The results of the drainage channel capacity of 38% figured that the drainage canal just only able to drain the flood event with a 2year return period. The upcoming flood is expected to increase by approximately 10% by 2030. The largest maximum capacity in Way Kuala and the largets flood volume occur in Way Kuripan, and the longest overflow occurs in Way Kuripan
