Clear-Water Scour Mechanism at Vibrating Monopile Foundations
(ASCE, 2024/07/01)Cyclic lateral loads on monopile foundations of offshore wind turbines induce vibrations that affect the clear-water scour process around the foundations. Previous experimental studies showed that the current-induced ... -
Evolution and Characterization of Pressurized Flow Conditions in Stormwater Collection Networks
(ASCE, 2024/03/01)Intense rain events and sprawling urbanization have contributed to more frequent flash flooding in cities, often due to the pressurization of drainage systems. Stormwater collection networks (SCNs) can become pressurized ... -
Control of Surface Plastic Transport in Natural Streams
(ASCE, 2024/07/01)In the aftermath of the worldwide severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic, the disposal of plastic and nonwoven fabric materials originating from personal protective equipment (PPE) into ... -
A Novel and Enhanced Calibration of the Tilting Weir as a Flow Measurement Structure
(ASCE, 2024/03/01)A large collection of laboratory measurements of piezometric head (h) and discharge (Q) were made over hydraulic models of a tilting weir at nine different angles, ranging from 25.7° to 90° within a 0.3-m-wide flume. These ... -
Nikuradse Roughness Height Derived from a Physically Based Model Applied to a River Channel with Dunes
(ASCE, 2024/07/01)The Nikuradse roughness height for a river channel or, equivalently, the friction factor (f) or Manning’s coefficient, are parameters required to calibrate hydrodynamic models used for flood risk management. In general, ... -
Laplace-Domain Fluid–Structure Interaction Solutions for Water Hammer Waves in a Pipe
(ASCE, 2024/03/01)Numerical methods generally need analytical solutions as test cases and validations in simplified problems. This work provides Laplace-domain explicit analytic solutions for fluid–structure interaction (FSI) water hammer ... -
Linear and Weakly Nonlinear Instabilities of Sand Waves Caused by a Turbulent Flow
(ASCE, 2024/05/01)This study examines the instability of sand waves (dunes and antidunes) from both linear and weakly nonlinear perspectives. The linear and weakly nonlinear analyses use the standard linearization and the center manifold-projection ... -
Near-Full-Scale Hydraulic Modeling of Fish-Friendly Culvert with Full-Height Sidewall Baffles
(ASCE, 2024/07/01)The adoption of baffles is relatively common in the construction of culverts, to assist with the upstream passage of migrating fish species. However, there still is a lack of systematic studies of the complicated hydraulic ... -
Flow in Sewers with Bottom Obstacles
(ASCE, 2024/07/01)This study conducted experiments to investigate the impact of bottom obstacles, specifically broad-crest weir-type and cylindrical obstacles, on the flow within a sewer pipe. It was observed that these two types of obstacles, ... -
Application of Material Point Method and Mohr-Coulomb Strain Softening Constitutive Model in Simulations of Multiphase Granular Flows
(ASCE, 2024/05/01)Sudden displacement of large volumes of liquid–granular mixtures in nature (dam-breaks, landslides, floods, etc.) are often reported to be deadly and destructive. The flow behavior of those mixtures is complex and depends ... -
Full Nonlinearity in Weakly Dispersive Boussinesq Models: Luxury or Necessity
(ASCE, 2024/01/01)Boussinesq-type (BT) models play a major role in coastal engineering applications. Due to their asymptotic nature, these models have lent themselves to constant study and improvement based on the inclusion/removal of ... -
2D Serre-Green-Naghdi Equations over Topography: Elliptic Operator Inversion Method
(ASCE, 2024/01/01)Multidimensional Serre–Green–Naghdi equations are numerically solved by using a natural hyperbolic-elliptic splitting. The hyperbolic step is solved by semidiscret finite volume methods. The elliptic step is related to ... -
Coupled-ISPH Framework for Modeling Tsunamis Induced by Landslides: Subaerial to Submerged
(ASCE, 2024/05/01)A novel coupled approach to modeling various stages of waves generated by different types of landslides (e.g., subaerial to submerged) through divergence-free incompressible smoothed particle hydrodynamics (ISPH) was ... -
A Predictive Model for the Initial Droplet Size and Velocity Distribution of Flood Discharge Atomization
(ASCE, 2024/05/01)During the discharge of floodwater from a hydropower station, a significant number of water droplets in motion are created in the downstream space. These droplets vary in size and velocity, causing challenges in determining ... -
Formulating Dynamic Pressure Characteristics at Flat Plunge Pool Bottom and Inside Rock Joints
(ASCE, 2024/05/01)Accurate prediction of pressure caused by plunging jets of high spillways is essential for assessing the bed rock scour initiation and expansion. The hydrodynamic pressure characteristics at plunge pools’ bottom and inside ... -
Anomaly Detection in Targeted Pipe Sections in Water Pipe Systems Using Hydroacoustic Signal Deconvolution
