Abstract: This paper investigated shield machine operation (SMO) errors involved in shield tunneling construction accidents based on the Technique for the Retrospective and Predictive Analysis of Cognitive Errors (TRACEr). Human ...

Abstract: As one of the three key components of state of Georgia’s state water plan, a surface water availability resource assessment (SWRA) involves three sequential steps, as follows: (1) synthesizing unimpaired flow (UIF) data ...

Abstract: The transient behavior of pipe systems is typically simulated using water hammer models [such as the method of characteristics (MOC)], or rigid water column (RWC) models depending on whether the hydraulic transition is ...

Abstract: Smart sewer systems consisting of water level sensors can effectively detect overflow events that may present a threat to water quality, human health, and the environment. Designing the optimal layout of the sensor with ...

Abstract: Internet of Things (IoT) technologies with distributed wireless sensors have been increasingly adopted in water utilities to build smart water networks (SWNs) for monitoring purposes. Based on the daily data collected from ...

Abstract: Hydraulic transient modeling is a critical tool for analyzing and managing pipeline systems. However, its practical application is often hindered by the need for precise boundary conditions and uncertainties in pipeline ...

Abstract: We present a computational approach for identifying the significance of uncertainty in assessing the consequences of sediment and nutrient transport in a section of the Chattahoochee River south of Lake Lanier, as it passes ...

Abstract: The propagation of pressure waves in water pipes is frequency dependent, which leads to these waves experiencing a frequency-dependent wave speed and attenuation, resulting in wave dissipation and dispersion. The effect ...

Abstract: The purpose of the paper is to present an approach for pipe burst detection, localization, and cross-sectional area quantification based on the changes in the discrete harmonic spectrogram and analysis of damping of fluid ...

Abstract: Timely pipe break and burst detection and localization are important for proactive management of water distribution systems (WDSs). This paper presents a novel timing-based method for fast localization of hydraulic transient ...
