Predicting Longitudinal Dispersion Coefficient in Natural Streams Using M5′ Model Tree
Publisher: American Society of Civil Engineers
Abstract: The longitudinal dispersion coefficient is a key parameter in determining the distribution of pollution concentration, especially in temporally time-varying source cases after full cross-sectional mixing has occurred. ...
Derivation of a New Model for Prediction of Wave Overtopping at Rubble Mound Structures
Publisher: American Society of Civil Engineers
Abstract: Prediction of wave overtopping is a key task in the design and safety assessment of coastal structures. In this study, M5′ model tree as a new soft-computing approach was used to develop a model for the prediction of the ...
Revisiting Longshore Sediment Transport Formulas
Publisher: ASCE
Abstract: Longshore sediment transport (LST) prediction is still a challenging task in coastal engineering, due to complexity in affecting physical processes. There have been studies to develop tools to predict the LST rate, but ...
Two-Phase Simulation of Wave-Induced Tunnel Scour beneath Marine Pipelines
Publisher: American Society of Civil Engineers
Abstract: An Eulerian two-phase flow model was presented and employed to investigate wave-induced tunnel scour beneath marine pipelines. The model is based on the Euler-Euler coupled governing equations for the fluid and sediment ...
Effect of Sea Level Rise on the Wave Overtopping Rate at Berm Breakwater
Publisher: American Society of Civil Engineers
Abstract: This study quantitatively assessed the risk in the overtopping performance of berm breakwaters due to sea level rise (SLR). To achieve this, a recent overtopping prediction formula that includes the influence of water depth ...
