RISEfficient Numerical Approach for Simultaneous Calibration of Pipe Roughness Coefficients and Nodal Demands for Water Distribution Systems
Publisher: American Society of Civil Engineers
Abstract: Hydraulic models have been widely used to facilitate the design, management, and operation of water distribution systems (WDS). However, model parameters including pipe roughness coefficients (PRCs) and nodal demands (NDs) ...
Better Understanding of the Capacity of Pressure Sensor Systems to Detect Pipe Burst within Water Distribution Networks
Publisher: American Society of Civil Engineers
Abstract: Leakage or pipe burst detection, often carried out by using the pressure sensor systems (PSSs) within a water distribution network (WDN), is critical to enable such networks to operate in a safe manner. The majority of ...
Investigating Effectiveness of Sensor Placement Strategies in Contamination Detection within Water Distribution Systems
Publisher: American Society of Civil Engineers
Abstract: Water quality sensors placed in water distribution systems (WDSs) are critical for detecting accidental or intentional contamination intrusion. This motivates research to optimally place a limited number of sensors for a ...
Air–Water Flows in a Deep Tunnel Downstream of a Dropshaft
Publisher: American Society of Civil Engineers
Abstract: AbstractDropshafts of deep tunnel systems can entrain a large amount of air, and the resulting
air–water interactions cause potential safety issues. In this study, the air–water
flow characteristics along a tunnel under ...
