Rainfall on March 30, 2016, cause inundation (high ± 8-60 cm) in SWPG Sudi Mampir. The purpose of this study to examine the capacity of the existing drainage and tidal influence of Martapura River. Maximum Rainfall with certain return period calculated by Log Pearson III. Maximum Discharge in drainage channels are calculated with Rational Method. Martapura River flood discharge calculation used Nakayasu HSS Method. Modeling of river flow profile with HEC-RAS v5.01. Calculation of back water in Telawang River used Direct Step Method. The results of the analysis, the rainfall that occurred at 138 mm equivalent R32tahun. There are 35 channels in SWPG inadequate. Volume of inundation rainfall in SWPG is 54470.07 m3, with a mean height in the land 10.3 cm and 47 cm on the roads. Discharge of Martapura river at the time equivalent Q2tahun (566.54 m3/sec). Volume and area of inundation due overflow of Martapura Rivers in SWPG is 2216.68 m3 and 11093.26 m2. High average inundation in the area around the Martapura River is ± 20 cm.Key words: Drainage, Inundation, Back Water, Tidal, Polder</description><publisher lang="en-US">Fakultas Teknik, Universitas Brawijaya</publisher><contributor lang="en-US"/><date>2017-05-18</date><type>Journal:Article</type><type>Other:info:eu-repo/semantics/publishedVersion</type><type>Journal:Article</type><type>File:application/pdf</type><identifier>https://jurnalpengairan.ub.ac.id/index.php/jtp/article/view/313</identifier><identifier>10.21776/ub.jtp.2017.008.01.02</identifier><source lang="en-US">Jurnal Teknik Pengairan: Journal of Water Resources Engineering; Vol 8, No 1 (2017); 15 - 25</source><source>2477-6068</source><source>2086-1761</source><language>eng</language><relation>https://jurnalpengairan.ub.ac.id/index.php/jtp/article/view/313/281</relation><rights lang="en-US">Copyright (c) 2017 Jurnal Teknik Pengairan</rights><recordID>article-313</recordID></dc>
