Background of the study
• Makassar city is a metropolitan, waterfront city
with total pop. 1.25 million (2009) and annual
growth of 23 %.
• The city shares the flood plain with the city of
Sungguminasa on the downstream of Jeneberang
river which experience regular flood from
Jeneberang
• The Bilibili Dam (functioned as flood regulator
and municipal water supply) has been operated
since 1999

Cont.
• The development (conversion) of Jeneberang
delta has flourished as the flood mitigation by
the dam and the access road into the delta
been constructed.
• The function of the flood control has been
doubted since the massive land slide on the
upstream of the river in 2004

downstream (Bilibili Dam and Jeneberang delta)

Method
• Supervised classification is performed to
identify the land use types of the delta
(Lillesand 1994, El-Kawy 2011)
• Source maps: Landsat 7TM (Sept. 1999),
• Source maps: Landsat 7TM (Sept. 1999),
Google Earth (Quikbird Apr. 2003 and Jul.
2010)

Research Procedure

Results and discussion
• Classification accuracy of Landsat image
classification is 88% (accurate)and Kappa coeff.
0.82 (Tab.1)
• The land use compositions in 1999 (total 1001.24
ha) are: Dryland farming and ricefield /natural
vegetation 38%; Wetlnd 41% and Buidup area
and residential 21% (Tab.2)
• The wetland and dryland farming/rice fields
continue to diminished (each left 14% in 2010)
and buildup area increased up to 73% in 2010)
(Tab. 3)

Future plan on the study area: The Center Point of Indonesia (CPI)

Conclusions
• The availability of low-cost satellite imagery
with high resolution provide solution to the
monitoring of land cover change includes the
urban sprawl.
• The impacts of urban sprawl on the natural
vegetation can be manage properly by using
available satellite imageries.
