【 摘 要 】

Makassar City is one of the major cities in Indonesia with a population of approximately 1.7 million inhabitants, which continues to grow and followed the development of urban infrastructure facilities. The development also resulted in adverse effects on the environment, especially for water catchment area turns into a watertight region resulting changes in surface runoff were greater, especially in the rainy season because the drainage coefficient values are increasing as well. The purpose of this study was to analyze the capacity of the capacity of drainage channels in terms of technical aspects, analyze and formulate efforts to address flooding in a drainage channel system environmentally friendly in terms of environmental aspects, and Calculating the cost and benefit the development of the handling of flooding with a drainage channel system environmentally friendly in terms of financial aspects. The results obtained from the analysis of the technical aspects there are 14 of 41 channel capacity is insufficient accommodation capacity, resulting in the analysis of environmental aspects require 867 infiltration wells, and 3.19 rate of Benefit Cost Ratio (BCR).
