29 Aug 2008TL;DR: In this paper, a method of surveying the condition of an underground enclosure including the steps of positioning at least one transmitter/receiver unit (including an antenna) within an underground, substantially nonconductive enclosure, such that a substantial air gap exists between the antenna and the inner wall of the enclosure, transmitting an ultra wideband (UWB) signal toward at least a portion of the outer wall, and processing the return signal in order to identify the interface between the soil and a region of conductivity different from the soil.

TL;DR: One of the first attempts to assess information regarding damage to underground pipelines and related infrastructure from hurricanes and flooding reveals a wide variety of direct and indirect damage mechanisms as mentioned in this paper, and utilities with underground networks potentially in harm's way would do well to learn from the experiences of their counterparts and take steps to prepare for and possibly alleviate future damage.
Abstract: One of the first attempts to assess information regarding damage to underground pipelines and related infrastructure from hurricanes and flooding reveals a wide variety of direct and indirect damage mechanisms. Utilities with underground networks potentially in harm’s way would do well to learn from the experiences of their counterparts and take steps to prepare for — and possibly alleviate — future damage.

TL;DR: In this paper, the authors describe the findings from a fourteen month study of the impact of hurricanes and other flooding mechanisms on buried infrastructure systems, which involved the development of an electronic database of detailed pipe damage data collected from six cities along the Mississippi and Louisiana coastal area.
Abstract: Hurricane Katrina brought the most severe flooding in modern US history, including the submergence of the city of New Orleans, a one million strong major metropolitan area. At present, there are no proven tools for assessing the damage sustained by buried infrastructure networks due to a hurricane or a flood. The paper describes the findings from a fourteen month study of the impact of Hurricanes and other flooding mechanisms on buried infrastructure systems. The study involved the development of an electronic database of detailed pipe damage data collected from six cities along the Mississippi and Louisiana coastal area, detailing the extent and distribution of damages to their buried pipe systems, and involved 25 municipal engineers, administrators, contractors and GIS analysts. A literature review of difficulties encountered during the recovery process in the aftermath of Hurricane Andrew and the 1997 Red River flood is followed by case histories for three Louisiana's cities - Slidell, Covington and Lake Charles (the former two were impacted by Hurricane Katrina while the latter by Hurricane Rita). The paper is concluded with a discussion of non-traditional damage mechanisms associated with hurricanes identified in the course of this study and potential mitigation measures to alleviate their adverse impact on buried infrastructure systems.
