Abstract:

Bandung is the capital city of the West Java Province. in 1995 the Bandung municipality had a population of about 2.5 million. Expansion of manufacturing and textile industries in the Bandung Basin, in 2007 more than 7.7 milion people inhabited the basin with density 2212 person/km2. Urbanization causes subsurface enviromental problems such as decrease of groundwater level, land subsidence, and flooding. The increase in both population and industrial activity in turn increased the degree of groundwater withdrawal from the aquifers in the Bandung Basin. Increased groundwater extraction has led to a rapid sinking of water tables on the plain. The land subsidence in Bandung Basin mainly caused by excessive groundwater extraction. The impact of land subsidence is aggravate the flooding in Bandung Basin. Flooding in Bandung Basin has been widely reported. Regular flooding occurs many times every year and heavy flooding usually happens when heavy rainfall. Flooding in Bandung Basin has brought huge economic losses to household, business interuption, industrial, agriculture, infrastructure, public facilities and social activities in affected area.

Keywords: Urbanization, land subsidence, groundwater extraction, flooding, economic losses
