An Integrated Framework To Assess Compound Flood Risks For Interdependent Critical Infrastructure In A Coastal Environment, Ying Zhang

Electronic Thesis and Dissertation Repository

Compound flooding refers to flood events caused by multiple factors, including marine processes (e.g. storm tides and waves), hydrometeorological signals (e.g. rainfall and river flows) among others. Saint Lucia is a tropical island in eastern Caribbean Sea, which is frequently affected by weather-related extreme events such as tropical storms and the associated risks are exacerbated due to its mountainous topography and high concentrations of infrastructure and human communities close to the coast. At the southern coast of Saint Lucia, significant infrastructures such as Hewanorra International Airport and Vieux Fort Seaport, and human settlements such as towns of Vieux Fort and …

Risk Analysis Of Natural Gas Distribution Pipelines With Respect To Third Party Damage, Joseph S. Santarelli

Electronic Thesis and Dissertation Repository

The objective of this study is to develop a quantitative method of evaluating the risk of third party damage (TPD) on natural gas distribution pipelines using available industry data and practical engineering experience. A risk model for TPD of gas distribution pipelines is developed to allow for a more robust decision making process and better prioritization of the allocation of resources for operators of natural gas distribution pipelines. The model consists of likelihood and consequence classification procedures to estimate the severity of TPD events within an area.

The TPD model consists of a fault tree (FTA) model to estimate the …
