We propose an empirical law for vertical nodal placement in tidal simulations that depends on a single parameter, p. The influence of dimensionless numbers on the optimal value of p is analysed through a series of numerical ...

The efficient resolution of the boundary layers occurring in geophysical flows has motivated the search for criteria to optimize the vertical nodal placement in three-dimensional shallow water models. This paper describes ...

Coastal area morphodynamic modeling systems couple modules for tidal hydrodynamics, wave propagation, sediment transport and bottom update. The non-linear coupling between these modules generates spurious oscillations and ...

Morphodynamic modeling systems are being subjected to a growing development over the last decade and increasingly appear as valuable tools for understanding and predicting coastal dynamics and morphological changes. The ...

Due to the increasing sand demand for construction and beach nourishment, offshore extraction is being considered as an alternative source. Long term morphological changes caused by such an extraction must be predicted ...

Hydrodynamics, salinity intrusion and stratification in the Guadiana estuary were characterized using two- and three-dimensional models for fresh water flows covering the range of monthly averaged river flows for dry to ...

A modeling system to simulate tidally driven morphodynamics is developed and assessed. The system couples an existing shallow water model with a new morphological updating model. Four innovative features to improve the ...

The effects of tidal flats on the hydrodynamics of the Tagus estuary are analysed using an accurate high-resolution shallow water model, supported by field data. Tidal flats act mainly as filters, rather than sinks, ...

The European Water Framework Directive requires that surface water bodies (both fresh and saline) reach a good ecological status by 2015. Dissolved oxygen is one of the indicators for the evaluation of the quality of water ...

A one-dimensional vertical (1-DV) numerical model that predicts mean sediment transport rates has been recently updated with state-of-the-art methods and tested against available field observations. Model calibration has ...
