The city of Makassar, the capital of South Sulawesi sited on the western coast of the South Sulawesi peninsula with population of 1.25 million in 2009, and annual growth of 23 %. The city laid on the northern side (downstream) of the Jeneberang River and shares the river???s floodplain with the city of Sungguminasa. The river???s watercourse has formed a delta on the coastal zone of Makassar. The delta is growing in size and the watercourse has shifted over the years. In the past, the area has been known to prone to the flood risks before a control dam was built upstream in Bilibili in 1999. With the presence of the Bilibili flood control dam, the development of Jeneberang delta has flourished. In the last 10 years, there has been an extensive development on the delta such as the elite residential of Tanjung Bunga, the large indoor theme parks of Trans Studio and the megaproject plan of the ???center point of Indonesia???. The dynamics of the delta???s landscape has been traced using remotely-sensed data and GIS technology. The analysis shows that the conversion rate has occurred rapidly in the last 10 years. The current land use shows that the area has been converted into residential and business area with the rate of conversion around 18% and 34% during the 1999 to 2003 and 2003 to 2010 respectively. The result obtained from image analysis also indicated that mangrove and wetland area has decreased over the 20 years period with reduction rate of about 14% and 13% respectively within the two period of study year.
