Abstract
Handling of flooding caused by changes in land use often causes changes and problems in the magnitude of runoff coefficient, discharge, water level, and drainage channel dimensions, as happened in Samarinda Seberang. The purpose of this study was to plan a drainage channel according to the priority scale using the Rational Modification Method as a Hydrological Analysis and Manning as a Hydraulics Analysis. Handling method is carried out in the form of structuring and planning the drainage system according to priority scale based on inundation parameters, economic studies, social and transportation disturbances, loss of housing areas, and property rights. The higher the criteria for handling the area is a priority. The results showed that the highest priority scale (610) was obtained on Cipto Mangunkusumo street, and the lowest priority scale (220) was at Bung Tomo street and Hasanuddin street. Cipto Mangunkusumo street as the highest priority scale will be planned for the first priority drainage channel with a design flood discharge in the 10 year return period (Q) 7.79 m3 / sec, the drainage channel dimension consists of the basic width of the channel (b) 0.77 m ∼ 0.80 m, channel peak width (T) 3.30 m, channel depth (h) 1.925 m, watch height (f) 0.6 m, total depth 2.52 m, and slope of channel wall (m) 1: 1).
