Abstract:

In order to explain the spatial nature of the distribution of eelgrass in the inner bays of Posyet Bay, numerical experiments were performed to simulate hydrodynamics and morphodynamic processes. The hydrodynamics was modeled using the Delft3D Flow model. The spectral wave model SWAN (Simulating WAves Near shore) was used to calculate the wind wave parameters (propagation direction, wave length and height, near-bottom orbital velocities). Alteration of coastal zone profile under the impact waves and the hydrodynamic of tidal and wind currents was performed using the Delft3-MOR morphodynamics m

Abstract Coastal inundation has a great impact on the environment, such as damage to infrastructure and pollution of land and water. One of the efforts to prevent coastal inundation is to predict the water level. Delft3D is a hydrodynamic model that's able to simulate the water level. Coastal inundation research using the Delft3D model is still rarely done in Indonesia, especially on the east coast of Sumatra. This research is conducted in Belawan coastal area by simulating the water level that caused the coastal inundation using the Delft3D model. The best bathymetry for the prediction of wat

Abstract:

Abstract Lhokseumawe City, one of the cities in Aceh, is situated close to a body of water with an area of 181.06 km2. Being in a coastal area, the city is highly susceptible to tidal flooding. The worst tidal flood in the area occurred on 26 May 2021, causing significant damage to residential areas. This study focuses on assessing the impact of sea level rise on the extent of tidal flood inundation and its consequences for residential areas along the coast of Lhokseumawe City. The analysis utilizes numerical modeling simulation carried out with the Delft3D application, specifically Delft3D-FL

Abstract:

Sand waves are large and transverse bed features, typically with lengths and heights of about 100-500 m and 2-10 m, respectively. The height can grow up to 30% of the average water depth, especially in shallow water conditions. Sand waves can migrate up to around 10 m/year and may profoundly impact subsea infrastructure, such as offshore pipelines and cables, key elements of offshore energy development. In this study, the evolution and migration of sand waves in the Dutch shoreface, North Sea 1986, was investigated using the Regional Oceanographic Modeling System (ROMS) and validated with DELF

Abstract:

Overland flood models with various degrees of complexity are often used to predict flooding in the coastal zone. One example of a compound flood model that is widely used is SFINCS (Leijnse et al., 2021). It can take into account the combined effects of tides, surge, waves, rainfall, wind and river discharge. Providing offshore boundary conditions of tide and surge for overland flood models typically falls in the realm of ocean circulation models, such as ADCIRC or Delft3D. Here we show that with some minor adjustments, the SFINCS model is also capable of simulating storm surge and tsunami pro

A 2-dimensional hydrodynamic model (RMA2 model) was applied to simulate currents and potential pollutant transport in Jiangyin-Xuliujing reach of Yangtze estuary. The result was compared and validated with a validated 3D model (Delft3D Model). The results indicate that the RMA2 model can achieve the requirements of reproducing and predicting the tidal flow and water levels. Based on RMA2 model simulations, a pollutant transport model (RMA4 model) was established to simulate the transport process of potential pollutant discharge from a sewage treatment plant for risk analysis.

The suspended sediment from the Serang River plays a crucial role in the development of the Wulan Delta. This study employs the open-source DELFT3D model to investigate seasonal hydrodynamics, sediment distribution, and morphodynamic changes in the delta.

Therefore, coastal dredging operations are performed to guarantee safe navigation. Nevertheless, these operations have a limited temporal effectiveness and require a high annual budget to be accomplished. The goa

Salinity intrusion through the estuaries in low-lying tide-dominated deltas is a serious threat that is expected to worsen in changing climatic conditions. This research makes a comparative analysis on the impact of salinity intrusion due to a reduced upstream discharge, a sea level rise, and cyclonic conditions to find which one of these event dominates the salinity intrusion. A calibrated and validated salinity model (Delft3D) and storm surge model (Delft Dashboard) are used to simulate the surface water salinity for different climatic conditions.

In this study, the 1994 Mindoro tsunami was numerically simulated by modelling of the initial water surface generated by the ground rupture and propagating the tsunami wave towards the coastal areas.

Moreover, the comparison of data-based methods with numerical model results is limited by uncertainties in measurements. These drawbacks can be partly overcome by a multi-model approach (MMA). In a case study to assess long-term sediment transport and morphodynamic processes for the German Bight, the AufMod research project applies two different methods for process-based modelling: UnTRIM-SediMorph and DELFT3D.
