Analisis Kapasitas Saluran Drainase pada Wilayah Padat Penduduk dengan Menggunakan Rational Modification Method

Abstract

Merauke City, as a city in a growth and development period, cannot be separated from various problems. The provision of inadequate city facilities and infrastructure is one of the factors in the situation, drainage, for example. Generally, drainage handling in Merauke City is not comprehensive, so it has yet to handle the problem of inundation or flooding entirely. In residential areas around Estuary 3, puddles or floods are often found whenever rain is high enough intensity. Given that the city of Merauke, including in a flat area or the absence of elevation differences, makes one of the causes of waterlogging or flooding. This study aims to determine the capacity of estuary drainage channels in 3 Merauke Regency to accommodate or drain planned flood discharge. The research method used in this study is the rational method. This study uses two analyses, namely hydrological analysis and hydraulics analysis, where hydrological analysis a carried out to determine planned flood discharge by calculating daily rainfall using probability distribution and hydraulics analysis to determine channel capacity discharge by calculating cross-sectional dimensions. Based on the results of the study shows that segment 1 to segment 10 has different capacity discharge (Qs) and flood discharge (Qr). Segment 1 is one of the channel segments capable of accommodating or draining planned flood discharge with a capacity discharge of 5.51"m" ^"3" "/sec" and flood discharge of 2.07 "m" ^"3" "/sec" (Qs>Qr). In segment 7, which is the segment with the minor channel discharge, namely channel capacity discharge (Qs) of 0.004 "m" ^"3" "/sec" and plan flood discharge (Qr) of 0.78"m" ^"3" "/sec" then, the channel is unable to accommodate or drain plan flood discharge (Qr > Qs). And for other segments, the track cannot adjust or drain the planned flood discharge (Qs

采用合理修正法分析人口稠密地区的排水道容量

Merauke市作为一个处于成长期和发展期的城市，其存在的各种问题是不可分割的。城市设施和基础设施不足是造成这种情况的因素之一，例如排水系统。总的来说，Merauke市的排水处理并不全面，因此它还没有完全处理淹没或洪水的问题。在河口3号附近的居民区，只要降雨强度足够大，就会出现水坑或洪水。鉴于梅洛克市，包括在一个平坦的地区或没有海拔差异，使内涝或洪水的原因之一。本研究旨在确定3 Merauke县河口排水通道的容量，以容纳或排出计划的洪水排放。本研究采用的研究方法是理性方法。本研究采用水文分析和水力学分析两种分析方法，其中水文分析通过概率分布计算日降雨量来确定计划洪流量，水力学分析通过计算断面尺寸来确定河道容量流量。研究结果表明，河段1 ~河段10具有不同的容量流量(Qs)和洪流量(Qr)。第1段是能够容纳或排水计划泄洪的河道段之一，泄洪能力为5.51米³/秒，泄洪能力为2.07米³/秒(Qs>Qr)。区段7是河道流量较小的区段，即河道容量流量(Qs)为0.004“m”^“3”/秒，计划洪流量(Qr)为0.78“m”^“3”/秒，此时河道无法容纳或排出计划洪流量(Qr >Qs)。其他区段的规划洪流量(Qs<Qr)在0.003-0.05“m”^“3”/秒之间，故意洪流量为0.21-1.19“m”^“3”/秒之间，轨道无法调节或排水。
