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 ...
The purpose of this study was to assess the quality of bottom sediment collected in the Bay of Vidy (Lake Geneva, Switzerland) which receives sewage treatment plant discharges from the city of Lausanne and its surroundings. Thirty-eight sediment samples we ...
Groundwater regime has an important role in coastal sediment transport near the coast and beach profile changes. Hitherto, accurate and complete nature of the interaction between wave motions, underground water and beach sediment transport is not yet known ...
Nearshore hydrodynamics and sediment transport in the nearshore zone were modeled numerically taking into account turbulent unsteady flow. The flow field was computed using the Reynolds Av-eraged Navier-Stokes equations with a k-ε turbulence closure model, ...
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 ...
A prominent parameter in dealing with swash and morphological evolution is the runup length or height, defined as the limit of landward sea. Therefore, it is necessary to predict the runup height in this area. In this paper, the abilities of a new Adaptive ...
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 ...
We describe and apply a point model of the joint evolution of tidal landforms and biota which incorporates the dynamics of intertidal vegetation; benthic microbial assemblages; erosional, depositional, and sediment exchange processes; wind-wave dynamics, a ...
A critical review of conceptual and mathematical models developed in recent decades on sediment transport in the swash zone is presented. Numerous studies of the hydrodynamics and sediment transport in the swash zone in recent years have pointed out the im ...
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 ...
