Tropical Cyclone Statistical Wind Estimation: In Regions with Rare Cyclone Occurrence

Tropical Cyclones (TCs) are in many regions responsible for severe damages and a great number of casualties, resulting from the severe wind speeds, rainfall, wave heights and storm surges. The recent hurricanes Harvey and Irma are examples of the great devastation that can be caused by a single event, and of the insufficient level of...

The reset of a subtidal bar during an energetic event: Application to Le Truc Vert beach case (France)

A large number of beach morphologies across the world exhibits nearshore sandbars with complex 3D patterns. During large storms, these shapes disappear and the bars get to a certain extent alongshore uniform. This phenomenon is called a reset. Numerous studies have been conducted on the development of the bar shapes (3D) or on the cross-shore...

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...

Modeling the hydrodynamics and salinity of the Pontchartrain Basin

The area of New Orleans was hit by Hurricane Katrina in August 2005. A large part of the city got flooded due to bad design, construction and maintenance of the levee system. In order to increase the level of protection of the city, the levees are heightened and strengthened in the framework of the Hurricane and Storm Damage and Risk Reduction...

Wave-Driven Longshore Currents in the Surf Zone

Recent study has shown that 3D computations of the morphological development of a coast shows irregularities compared with the 2DH (depth-averaged) computations. Therefore a validation of the surf zone currents computed using the 2DH (depth-averaged) and 3D approach in Delft3D is made. The 2DH and 3D approach are compared using an idealized case...
