RISHigh-Order Perturbation Approach for Wave Transformation by Applying Advection-Diffusion Equation via Karhunen–Loeve Expansion
Publisher: American Society of Civil Engineers
Abstract: An efficient approach, termed the Karhunen–Loeve expansion (KLE), for uncertainty analysis of flow in open-channel flow is applied. The initial condition, as a random field, is described in the form of two consecutive ...
Long-Term Groundwater-Level Forecasting in Shallow and Deep Wells Using Wavelet Neural Networks Trained by an Improved Harmony Search Algorithm
Publisher: American Society of Civil Engineers
Abstract: This study proposes a model using wavelet neural networks (WNNs) trained by a novel improved harmony search (IHS) algorithm to forecast daily groundwater level (GWL) in a shallow well and a deep well in Florida and Arkansas, ...
Integrated Multisource Data Assimilation and NSGA-II Multiobjective Optimization Framework for Streamflow Simulations
Publisher: American Society of Civil Engineers
Abstract: Given the importance of input data, particularly precipitation, in hydrologic modeling for streamflow simulation, there has been growing emphasis on developing frameworks that harness multiple data sources concurrently to ...
Induced Vibration of a Surface Foundation atop a Fluid-Conveying Embedded Pipe
Publisher: ASCE
Abstract: The dynamical behavior of a system containing a surface foundation atop a fluid-conveying pipe that is embedded in soil beneath the foundation is investigated. A Winkler–Voigt model is presented to simulate the interaction ...
