Long wave run-up on random beaches.
The estimation of the maximum wave run-up height is a problem of practical importance. Most of the analytical and numerical studies are limited to a constant slope plain shore and to the classical nonlinear shallow water equations. However, in nature the shore is characterized by some roughness. In order to take into account the effects of the bottom rugosity, various ad hoc friction terms are ...
متن کاملOn Selecting Parametric Link Transformation Families in Generalized Linear Models
The use of parametric link transformation families in generalized linear models (GLM) has been shown to improve substantially the t of standard analyses using a xed link in some data sets (see Czado 1993], for example). When link and regression parameters are globally orthogonal (Cox and Reid 1987]), then the variance innation of the regression parameter estimates due to the additional estimati...
متن کاملLinear parametric hydrodynamic models based on numerical wave tank experiments
Hydrodynamic models are important for the design and control of wave energy converters. Traditionally they have been obtained using velocity potential/boundary element type methods, however associated assumptions of inviscid fluid, irrotational flow, small waves and small body motions are a major limitation of this modelling approach, since WECs are designed to operate over wide wave amplitude ...
متن کاملImpacts of wave and tidal forcing on 3D nearshore processes on natural beaches. Part I: Flow and turbulence fields
The major objective of this study was to develop further understanding of 3D nearshore hydrodynamics under a variety of wave and tidal forcing conditions. The main tool used was a comprehensive 3D numerical model – combining the flow module of Delft3D with the WAVE solver of XBeach – of nearshore hydroand morphodynamics that can simulate flow, sediment transport, and morphological evolution. Su...
متن کاملDune growth on natural and nourished beaches : ‘ A new perspective ’
This thesis describes dune development on natural and nourished beaches on an engineering timescale. Using a study of both literature and data gathered from the Dutch coast, a new hypothesis regarding the causes of variability in dune evolution is proposed. Following this hypothesis assumptions are made on the basis of which a conceptual model is developed that includes both the accretive and e...
