Morphological Response of the Dutch Sandy Coast to Accelerated Sea Level Rise: A process-based modelling approach using Delft3D, applied to the Delfland coast

Accelerated sea level rise (SLR) is predicted to have multiple adverse impacts on the coastal zone, aggravating phenomena such as coastal erosion on sandy coasts. For climate change adaptation planning and informing policy, morphodynamic changes occurring at coastlines are becoming increasingly important. In this study, a calibrated Delft3D...

Using Non-Stationary Training Images from Process-Based Models for Multiple Point Geostatistics Stochastic Generation of Fluvial-Dominated Delta Reservoir Model

Process-based method forward stratigraphic modelling provides advantages in reservoir modelling by simulating the geological process mathematically, and the genesis of geologic formations over time (Michael et al., 2010). In spite of its advantages, Miller et al. (2008) have recognised significant challenges in process-based simulation models,...

The influence of dredging activities on the morphological development of the Columbia River mouth

This is a numerical modelling study on the impact of dredging and disposal activities on the long-term morphological development of the Columbia River mouth (MCR). Dredging activities removed 120 Mm3 of sand from the MCR during the studied interval between 1958 and 1999. Only one-third of this volume was disposed in the active littoral zone....

Process-Based Modelling of the Brent Delta: Influence of paleobathymetry from the Oseberg Fm. pinch out on the wave dominated Brent Delta progradation. North Sea Norwegian Sector – Huldra Field

The stratigraphic and tectonic framework of the Brent Group and their respective depositional environments is well studied and documented in the literature. The lower progradational Brent deltaic sequence is the response of a high sediment supply rate outpacing the accommodation space rate caused by subsidence and an overall sea level rise stage...

Modeling the Evolution of the Wax Lake Delta in Atchafalaya Bay, Louisiana

In this study, a process-based, depth-averaged Delft3D hydrodynamic and morphologic model of the Wax Lake Delta in Atchafalaya Bay, Louisiana was developed to simulate a five year period of delta development. The purpose of this modeling effort was to test the ability of process-based modeling tools to successfully simulate typical delta...

Process-Based Modelling of the Brent Delta, Gullfaks Area, Norway

With the use of the process-based geological model Delft3D a base case model is set up to simulate the Brent delta using Gullfaks field conditions as appeared during the Aalenian and Bajocian periods in the Mid-Jurassic. The aim is to visualize and comprehend the morphology and stratigraphy of the base case upon changing both wave conditions and...

Long-term morphological modelling of the mouth of the Columbia River

With the construction of a process-based long-term morphological model (Delft3D) for the Mouth of the Columbia River (MCR), a first approach is made in trying to simulating the long-term morphodynamics of the MCR. Focus is on simulating the observed morphological changes for the post-jetty period of 1926-1958. The model is supplied with a high...

Modeling the interaction between morphodynamics and vegetation in the Nisqually River estuary

Due to growing human activity in coastal zones, there is an increasing stress on salt marshes all over the world. These intertidal wetlands were often seen as coastal ‘wasteland’ and large areas were reclaimed for urban development and agriculture. In Puget Sound, a system of interconnected marine waterways and basins in the northwest of the...
