The interaction between tide, river runoff, and wind in coastal lagoons induces complex salinity gradients, which are remarkable when the meteorological forcing is exacerbated. This work aims to characterize structure under extreme freshwater events Ria de Aveiro lagoon (Portugal). Delft3D model was implemented validated 3D mode used perform simulations forced with scenarios. Results show that ...

One of the troublesome aspects of numerical modeling is to determine open boundaries for a model and to make sure that the boundary conditions employed at the open boundaries are compatible with physical processes being simulated within the interior of the model domain. In this investigation the accuracy of the water level data derived from delft3D employing nesting procedure were studied. Thes...

Salt-marsh plants play important roles in the hydrodynamics and sediment transport deposition processes coastal regions. The Delft3D model was applied to quantify influence of salt-marsh on hydrodynamic characteristics suspended a wetland, reveal contribution trapping local area. Specifically, spatial distributions were acquired from remote sensing images coupled with model. A comparison showed...

Abstract PT. Teluk Lamong Terminal is one of the busiest port terminals in Indonesia. Such conditions require development facility area for reclamation. This reclamation can potentially change seabed’s contours and current patterns bay Surabaya. Therefore, Author will conduct a research study to determine impact on speed pattern existing post-reclamation bay, conducted numerical modeling with D...

Numerical models are essential tools for the study and analysis of hydrodynamics estuarine systems. However, model results contain uncertainties, which need to be minimized increase accuracy predictions. In this work, ensemble technique is proposed as a solution improve hydrodynamic forecasts regions. Two numerical models, openTELEMAC-MASCARET Delft3D, were considered application two Portuguese...

Sandy coastlines in Chile currently have strong erosive tendencies. However, little is known about the morphodynamics of these coastlines; such knowledge would allow us to understand coastline changes and incorporate this into coastal management. Accordingly, historical scale erosion morphodynamic characteristics six beaches Arauco Gulf, central-southern (36° S), were analyzed determine prevail...

Belawan port and coastal areas were also not spared from the impact of tidal flood. This study aims to determine performance Delft3D hydrodynamic model in simulating sea level waves floods at area. Final operational global analysis data, MSLP data NOAA/NCEP, ECMWF used run model. The output was verified by using tide gauge observation BIG (Geospatial Information Agency). research resulted a map...

The precise location of the seismic source 1755 CE Great Lisbon earthquake is still uncertain. aim this work to use an onland sedimentary record in southern Portugal test and validate sources for earthquake. To achieve this, tsunami deposit thicknesses from over 150 cores collected at Salgados were compared results a sediment transport model (Delft3D-FLOW) that simulates propagation, inundation...

This book presents a method for hydrodynamic modelling of tidal power plants. In the face climate change, plants will play an important role in transition to renewable energy and decarbonisation society. Tidal is not dependent on weather conditions fully predictable, allowing accurate forecasts several years into future. Its main drawback that it limited areas with high ranges, such as Atlantic...

The study was carried out in Semarang City, Central Java, Indonesia, along the East Canal Flood River. There are several community activities that produce some pollutants and total suspended solids (TSS) one of elements is. river transports these to estuary. These coastal regions provide exceptional life support for creatures. This attempts determine concentration value solids, its suitability ...
