Nautical safety on Dutch inland waterways, a study to detect anomalous vessel behaviour based on AIS data

Currently, inland waterway safety assessments rely heavily on historic accident data and expert opinions, often lacking comprehensive qualitative and quantitative information. Addressing this gap, this thesis introduces a method based on Automatic Identification System (AIS) data to identify anomalous vessel behaviour for enhancing safety...

Route optimization in dynamic flow fields: avigation system for the North Sea and Wadden Sea

This thesis introduces a new algorithm for optimising shipping routes within a dredging project. Highly dynamic and time-dependent hydrodynamic features influence shipping routes. Due to the complex interactions between the horizontal tide, vertical tide, stratifying forces, wind-driven forces, and limited water-depth, shipping routes were...

Implementing the WPS Standard; A Case Study for Dissemination of Coastal and Marine Tools

The Open Geospatial Consortium has been developing a wide range of open standards for the field of Geographical Information (GI). One of the standards allows for remote processing; the Web Processing Service (WPS). WPS has not been implemented in many project yet but it is a promising standard which can also be applied outside the field of GI....

Simulating Barrier Island Evolution: Coupling Process-Based Models

Barrier islands are important features in the coastal zone, among others because they shelter the mainland from waves and storm surge. Thus, the degradation of barrier islands can pose a threat to coastal safety. Hence, there is a societal demand for understanding and predicting barrier island evolution. High energy events, such as storms and...

Impact Assessment of Extreme Storm Events Using a Bayesian Network

The most densely populated and economical most valuable areas in The Netherlands lie below mean sea level. These areas are protected against the sea by a coastal dune system. The vital importance of this dune system is reflected in the extensive collection of Dutch legal regulations that ensure the safety level of the dunes. Current safety...

Probabilistic modelling of extreme beach erosion using XBeach

The long series (>30 year) of measurement data of erosion events at Narrabeen beach (NWS, Australia) provides insight in erosion volumes and their return periods in this area. The aim of this study was to replicate these data using XBeach in order to assess the validity of both the Joint Probability Model (JPM) and XBeach on beaches such as...

Morphodynamic analysis Ecobeach project

The Ecobeach project is a newly invented method to defend the coast against erosion. Ecobeach is a coastal defense system based on the principle of passively draining the beach. This Thesis looks into possible morphological changes induced by the Ecobeach test at Egmond aan Zee performed by Rijkswaterstaat and BAM.
