This research was built from the shifting in urbanization patterns as a result of KBU’s regional regulation. On the other side, extreme precipitation in Bandung basin not only happens in KBU but also varies spatially. The urbanization shifting and spatial variation of extreme precipitation will increase flood discharge in other places. Therefore, this research was conducted to see the impact of spatial variations of extreme precipitation and land-use on flood discharge in Bandung basin. There are three stages to see the impact of spatial variations of extreme precipitation and land use on flood discharge in Bandung basin, 1) Extreme precipitation data processing, 2) Land-use data processing, and 3) Model simulation. Extreme precipitation data processing results will be seen as characteristics of each region’s extreme precipitation and used as model’s input. The model simulation will be based on three land-use scenarios: 1989 (pre-regional regulation), 2009 (year of regional regulation), and 2019 (post regional regulation). Those are the results of land-use data processing. Urbanization shifting to north non-KBU and east area occurred as an impact of regional regulation about KBU. It affects a big impact to flood discharge in east area and relatively no impact to flood discharge in north non-KBU area. Despite extreme precipitation frequency and volume, south area has the biggest value. In addition, with south area land use condition, south area has a potential as the biggest contributor in Cekungan Bandung’s flood. Therefore, flood’s study in south area is needed as a priority.
