Impact Modelling of Hurricane Sandy on the Rockaways: Relating high-resolution storm characteristics to observed impact with use of Bayesian Belief Networks

Hurricane Sandy (2012), which made landfall in New Jersey on October 29th, made devastating impact on the East Coast of the USA and struck major parts of New York City, including the economic centre of Manhattan. The total damage (in the USA and Caribbean) is in excess of 100 billion US$ with estimates ranging between 78 and 97 billion US$ for...

Incorporation of the effects of accelerating flow in the design of granular bed protections

For the design of granular bed protections often a stability parameter is used. The stability parameter represents the forces that are acting on the stones and is used to predict the response of the bed to these forces. Existing parameters are often derived for a limited range of application. When the parameter is used outside this range, the...

The Effect of Multiple Storms on the Stability of Near-Bed Structures

Pipeline covers on the seabed are called near-bed structures which are generally made of rip rap. The crest height of a near-bed structure is such that waves do not break over it. Near-bed structures are used to protect pipelines against fishing equipment, ship anchors, dropped objects and preventing destabilizing of the pipeline. There are two...

A generic quantitative damage description for rubble mound structures: Investigation of damage to roundheads by using a 3D high-resolution measurement technique in a physical model

Breakwaters are used for reducing wave height in harbours or divert sediment. One of the types of breakwaters is the rubble mound breakwater. These structures are constructed with smaller quarry rock as core and larger quarry rock as outer layer. For economical reasons, the design allows some damage to the armour layer. The amount of damage is...

Fort Bay, Saba: A study on hurricane condities

Fort Bay harbour is a small harbour, located at the South of the island of Saba. This island is part of the Netherlands Antilles and it is situated in the Caribbean Sea where hurricanes may occur several times a year. Since its construction in 1972, Fort Bay harbour has experienced several hurricanes. Unfortunately some of these hurricanes were...

Tripoli breakwater reconstruction - evaluation and modification 1982 NEDECO design

This study comprises the design of the reconstruction of the main breakwater of the Tripoli Harbour in Libya. Tripoli harbour is one of the oldest harbours of North Africa situated on the Southern coast of Mediterranean Sea. The harbour as it existed in 1972 was built at the beginning of this century and was protected by two main breakwaters....

Mitigerende maatregelen bij de Noord-Zuidlijn te Amsterdam

Bij de aanleg van de Noord/Zuid lijn in Amsterdam moet in de binnenstad een deel van het tracé worden gerealiseerd met behulp van de tunnelboormethode. Gezien de grondverplaatsingen en grondontspanning veroorzaakt door volumeverlies in en consolidatie van de grond tijdens het tunnelboorproces, worden problemen verwacht met betrekking tot ...
