Environmental conditions in the study site that frequently occurs Takalar City Overflow / floods so that flood patterns control development is necessary to maintain public activities due to infrastructure damage caused by the overflow of Pappa river. This paper aims to establish a model of control by way of the construction of dams, development reservoir regulation, or a combination of regulation and dams.
