Study of mathematical model application in analysis of tello river flood

Abstract

River is a natural element that was instrumental in shaping the pattern of life of a community. For example, in the city of Makassar, one of the essential rivers is the river Tello. However, in addition to many benefits, often also causing disasters, namely floods. One way to cope with floods in this area are studying the phenomenon and the vulnerability of flood conditions in watersheds using hydrologic approach through flood search method known as kinematic Muskingum method. Results from this study are expected to provide an alternative solution with the optimal treatment approach the river hydrological conditions of Tello River. This research was conducted by processing rainfall data at three stations along the stream to get the value of flood discharge. Then proceed with processing the flood discharge plan with the inflow into the Muskingum method to get the value of the outflow. Segments of the river reviewed so far is 20 km and by dividing the share of the river as many as 5 segments with 4 km each. The value of x is determined between 0.1 to 0.3 and a K value of between 0.16 to 0.57. These values are used to calculate get the flood outflow of each segment of the river.
