A Global-Local Artificial Neural Network with Application to Wave Overtopping Prediction [PDF]
, 2005 We present a hybrid Radial Basis Function (RBF) - sigmoid neural network with a three-step training algorithm that utilises both global search and gradient descent training. We test the effectiveness of our method using four synthetic datasets and demonstrate its use in wave overtopping prediction.

Wave overtopping and toe scouring at a plain vertical seawall with shingle foreshore : a physical model study [PDF]
, 2019 This paper describes a physical model study to investigate the wave overtopping and toe scouring at a plain vertical wall with a shingle foreshore. A matrix of 180 experimental test conditions were performed in a 2D wave flume, with an approximate scale ...

WAVE OVERTOPPING PREDICTION OF A GENTLE SLOPED STEPPED REVETMENT
Coastal Engineering Proceedings, 2018 Stepped revetments are multi-functional coastal structures o ering protection against flooding. Despite the fact that these structures have been implemented for more than 60 years, comprehensive design guidance is lacking. Previous research studied overtopping of stepped revetments with slopes ranging between 1:1 to 1:4. To address the knowledge gap of

The Influence of Geometrical Shape Changes on Wave Overtopping: a Laboratory and SPH Numerical Study [PDF]
, 2018 This paper presents laboratory investigations of four “retrofit” suggestions for attenuating the overtopping from vertical seawall. Two-dimensional physical model experiments were performed on a vertical seawall with a 1:20 sloping foreshore ...

Wave overtopping at dykes with topped vertical wall - Impacts of oblique wave attack [PDF]
, 2012 Hydraulic model tests at a scale of 1:10 are carried out in a 40 m x 25 m wave basin with a state-of-the-art 3D wave generator in order to collect wave overtopping data at vertical walls and dykes with topped vertical walls.

Wave Overtopping Database As the Starting Point for a Neural Network Prediction Method [PDF]
Coastal Structures 2003, 2004 The European Union (EU) CLASH project stands for “Crash Level Assessment of coastal Structures by full scale monitoring, neural network prediction and Hazard analysis on permissible wave overtopping. One of the objectives of CLASH is to produce a generally applicable prediction method for wave overtopping at coastal structures based on permissible wave

Boreas, EarlyView.Map of Lower sediment (LS) thickness is a surrogate for the distribution of Thorncliffe Formation (TF) and ~75% of TF thickness from the slope of Niagara Escarpment east to Brighton. Inset images show the LS sequence at the Don Valleys brickyards (DVBY) and undeformed TF sand and gravel (~15 m) below Newmarket Till (NT) at sites L and Co.

Spatiotemporal numerical modeling of wave overtopping flow over dike crests and landward slopes
Applied Ocean ResearchWave overtopping can cause severe erosion on the crest and landward slope of a dike. Accurate erosion prediction requires resolving the spatiotemporal evolution of overtopping flow, which remains insufficiently understood.
