Numerical simulation of surf-swash zone motions and turbulent flow

David Andrew Barry, Roham Bakhtyar

A two-dimensional numerical model was presented for the simulation of wave breaking, runup and turbulence in the surf and swash zones. The main components of the model are the Reynolds-Averaged Navier-Stokes equations describing the average motion of a tur ...

Prediction of Longshore Sediment Transport Using Soft Computing Techniques

David Andrew Barry, Roham Bakhtyar

An important task for coastal engineers is to predict the sediment transport rates in coastal regions with correct estimation of this transport rate, it is possible to predict both natural morphological or beach morphology changes and the influence of coas ...

Longshore sediment transport estimation using fuzzy inference system

Roham Bakhtyar

Accurate prediction of longshore sediment transport in the nearshore is essential for the control of shoreline erosion and beach evolution. In this paper, the abilities of an hybrid Adaptive-Network-Based Fuzzy Inference System (ANFIS), a Fuzzy Inference S ...

Numerical simulation of wave breaking and wave runup in the nearshore zone

Roham Bakhtyar

When the wave approaches to coast, the wave steepness, which is the ratio of wave height to water depth increases due to depth re-duction. This increase continues to a certain extent, until finally at this limit, the wave breaks. Wave breaking results in t ...

Biologically-controlled multiple equilibria of tidal landforms and the fate of the Venice lagoon

Andrea Rinaldo

Looking across a tidal landscape, can one foresee the signs of impending shifts among different geomorphological structures? This is a question of paramount importance considering the ecological, cultural and socio-economic relevance of tidal environments ...

Efficiency of Brushwood fences in shore protection against wind-wave induced erosion

Selim Sayah

Shore protection in confined water bodies is of major importance in Switzerland where many lakes suffer severe shore erosion. It occurs mainly in shallow zones due to several reasons such as: the fluctuations of the water level , the wind-wave impact durin ...

Two-dimensional analytical solution for tide-induced watertable fluctuations in a sandy rhythmic coastline

David Andrew Barry

Modelling of tide-induced watertable fluctuations in coastal unconfined aquifers has, for many years, been based on the assumptions of one-dimensional shallow flow and a vertical beach face. This approach is based on the Boussinesq equation, neglecting var ...

Two-dimensional approximation for tide-induced watertable fluctuations in a sloping sandy beach

David Andrew Barry

The prediction of watertable fluctuations in a coastal aquifer is important for coastal management. However, most previous approaches have based on the one-dimensional Boussinesq equation, neglecting variations in the coastline and beach slope. In this pap ...

A geomorphic study of lagoonal landforms

Andrea Rinaldo

We perform an analysis of the observational morphological structure of a tidal landscape aimed at examining key assumptions on the geomorphological evolution of wetlands, lagoons, estuarine areas and tidal environments in general. The issues addressed pert ...

2005

We review recent advances in the study of tidal landforms and their embedded vegetation patterns within the lagoon of Venice, aiming at clues on the coevolution of their morphodynamic and ecological features. The observation and analysis of network and veg ...
