Abstract

Population growth in the central area of the city population will result in the formation of a settlement environment that tends to deteriorate, for example the emergence of slums. Riverbanks that are used as settlements caused by the overflow of the Unus river caused by reduced river storage capacity due to the presence of increasingly large sedimentation and flow rates. Normalization planning must be done on the Unus river sould ceried out to control the flood. River widening and embankment structur are alternatives that can be done to control flooding on the Unus river. In this study hydrological analysis using 10 years of rainfall data from 2008-2017 consisted of Gunung Sari station, Kuripan, Aik Nyet and Jurang Sate. To find out the magnitude of the flood discharge design using the Nakayasu synthetic unit Hydrograph method with a calculation of 25 years return period. After the normalization effort has been carried out, the new Unus river dimension is obtained with a discharge of 69,014 m3 / sec. At p6 point with a river height of 5.5 m, the width of the riverbed is 15 m and the width of the river is 32 m, at point p44 pile with a river height of 6.5 m, the width of the riverbed is 15 m and the width of the river is20 m. at p44 point with river height 4.5 m, riverbed width 15 m and width over river 20 m, For analysis of river hydraulics, HEC-RAS 4.10.Was used Of the type of flow used is steady flow analysis because the flow parameters used ware flood flows and the average river slope. This was done by looking at the conditions in the field using river widening
