Abstract

Jeneberang river has an important role to control flood in Makassar and Gowa. The estuary is an area of expenditure river water, especially during flood discharges it is a result of a great number of sediment transportation from upstream that will undergo a huge deposition, so the function is not able to performed optimally, especially during flood discharge and partly transported to the beach around the estuary such as, Tanjung Bunga beach and Barombong beach. This study aimed to analyze the type of sediments based on diameter 50 (D50) and the distribution of sediments and how to handle it. The methodology of sediment sampling was conducted directly in the field based on the point of the review that had been determined as data acquisition. Furthermore, sediment samples were analyzed in the laboratory to determine the type of sediments and the distribution. The type of sediments obtained with the number of the review point 6 (six) location of the material, there were 7,56% gravel material, 73,43% sand, 3,47% clay, and 18,05% silt. Based on those sediment types, Jeneberang estuary categorized in the form of a coast as type of a sandy beach and distribution of the size sand grain is equal because the average value (So) is 1,286 located between 1,0 and 1,5 (1,0 = So = 1,5). The alternative treatment is divided into two ways, there are short-term and long-term treatment whereas in the short-term ways is done by doing dredged and for long-term treatment is done by making jetty that pointed out.
