Large-scale and local morphological impact along the northern side of DELTA 21

This report investigates the long-term morphological changes caused by the DELTA 21 project at the northern side, including the large scale morphological development with Delft3D model and at local scale the coastline deformation with UNIBEST-CL model. The necessity of the layout design improvement of DELTA 21 is analyzed by comparing different...

Impact of a port and its structures on the morphodynamics of a tidal basin and its adjacent coast: A case study of Bluefields Bay, Nicaragua

To improve the socioeconomic situation in the Republic of Nicaragua, the government has decided to strengthen the country’s transport infrastructure by building a port on the Caribbean coast. The future port will be in Bluefields Bay, which can be characterised as a lagoon-shaped estuary. The inner basin is connected to the sea by two tidal...

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...

The morphological effects of sediment diversions the Lower Mississippi River

The wetlands in the Mississippi delta (USA) are drastically subsiding and eroding. Many projects and researches are ongoing to determine how this “drowning effect” of the delta can be stopped. One of the solutions that could be feasible is implementing sediment diversions in the levees of the Lower Mississippi River in order to divert sediment...
