Abstract

Abstract. The nipa - nipa regulation pool is one of the flood control building facilities built after the confluence of the Tallo River and the Mangalarang River to control floods in Makassar City and Maros Regency due to the overflow of the Tallo River downstream with a system operation to collect water entering through the side channel spillway during peak flooding for a while and drain it back to the Tallo River . This study aims to (1) analyze the flood discharge of the tallo river which can be reduced by the side spillway, (2) to analyze the effect of the Nipa - Nipa Regulated Pool on the downstream part of the Tallo River. Nipa Against Flood Control in the Tallo River to control flooding in the downstream part of the river using the flood tracking method. This research method is a method of tracking floods and calculating the design flood discharge using the HSS Nakayasu and ITB II methods and simulation with HEC-RAS 5.0.7. The results of this analysis are in order to support the control of maximum urban floods due to the overflow of the downstream tallo river and support sustainable development.

Keywords: river,flood fouting, and the side spillway
