ANALISA RUAS DRAINASE PERUMAHAN SAMUDERA AFROZA 3, KELURAHAN PASIR PUTIH, KECAMATAN JAMBI SELATAN, KOTA JAMBI

Abstract

Flooding occurred in the Samudera Afroza 3 RT 16 settelemnt area because rainwater fell with high intensity and for more than 2 hours. Existing drainage analysis can help add information data for handling flooding in drainage sections. The method for collecting rainfall data is the maximum daily rainfall average for 10 years. Determining the probability was carried out by the gumbel, normal, log-normal and log-person type III distribution probability tests and determining the water flow rate using the rational formula. Calculation of drainage dimensions using the Manning equation. The results of probability tests using chi-square, Smirnov-Kolmogurov (analysis), and Smirnov-Kolmogurov 0.477; 05 and 0.551.
