Performance of Water Supply Lines in a Post-Earthquake Scenario

Abstract

An earthquake can affect a vast category of buried lifelines performance such as water distribution system, sewage disposal system, petroleum enterprises, etc. In the present study, damage in terms of performance and working of water distribution system after severe earthquakes in a metropolitan city is assessed to develop serviceability priorities. A system simulation based on Kameda's model is also developed for obtaining useful information on the behavior of the water supply system in the pre-and post-earthquake scenario. The event modeled is the earthquake that is believed to produce extensive losses to life and property. The priorities strategy for rehabilitation of buried water distribution system is framed considering important factors such as damage in terms of leakage, reliable water demand after earthquake damage, and water distribution path length. In this study, repair management is applied systematically to restore the reliable water supply in a water distribution path. The recommendations are framed and priority of repair of the water distribution system of various paths of city zone is established such as pre-assuming a post-earthquake scenario, from the case study of one of the most important metropolitan cities of Asian country i.e., Delhi.

Kahramanmaraş Merkezli Depremler Sonrası İçin Akademik Öneriler

“…Dolayısı ile altyapı sistemlerinin durumlarının tespiti afet sonrasında hızlıca kontrol edilmelidir. Altyapı sistemlerindeki hasarlar aynı zamanda arama kurtarma çalışmalarını da sekteye uğratabilmektedir (Hasan 2021). Altyapılarla alakalı risklerin doğru bir şekilde yürütülebilmesi için bütünleşik bir planlama ile afetlerin neden olabileceği problemlerin türünün, boyutunun ve dağılımının ileri tekniklerle tahmin edilmesi; ayrıca zemin özelliklerinin ne tür hasarlarlar ilişkili olabileceğinin anlaşılması gerekmektedir (Bagriacik vd.…”

Research on Seismic Connectivity Reliability Analysis of Water Distribution System Based on CUDA

“…The water distribution system (WDS) is an indispensable infrastructure in urban lifeline projects, with the characteristics of wide spatial distribution and strong damage correlation, which has been severely damaged in previous destructive earthquakes, resulting in partial or complete failure of the urban water supply function and seriously affecting people's lives [4][5][6][7][8][9]. Therefore, it is necessary to carry out seismic connectivity reliability (SCR) analysis to understand the ability of a WDS to perform its function in the first instance and provide scientific support for the pre-earthquake reinforcement and post-earthquake reconstruction of a WDS, and as a preliminary analysis of the water network resilience.…”
