Re-use of immersed tunnels: An innovative method for recovering, regenerating and reusing immersed tunnels by temporarily re-floating

Immersed tunnels, located in waterways, could be a limiting factor in the dredging in waterways. This dredging is required since cargo vessels draught increased the past decades. In this thesis a new method is defined for temporarily, effectively, re-floating immersed tunnels. With this method extra risks arise, for these risks’ measures are...

Evaluation of the feasibility of solutions to flash flooding in the municipality of Tirana (Albania)

In the recent years, several cases of flash floods have been reported in the Municipality of Tirana, causing important material damage in the region. One of the most devastating events occurred in December 2017, which flooded the City Park area (West of the Municipality of Tirana). This area is strategical because it...

Don't waste the river!: Limuthi Re-Cycle Valley

These are challenges we have worked on with a multidisciplinary team of students from the Technical University of Delft in the Netherlands and several universities in Albania. Eventually, a development strategy was made for three locations in and around the capital Tirana. This report is a landscape architectural elaboration of one of these...

Spatial integration of dike reinforcements: Development of a method that compares the spatial influence of design alternatives

In the Netherlands, a new assessment method for the required safety level of primary flood defences is introduced in the Water Act. It is estimated that currently roughly 1900 kilometres of flood protection does not meet the safety requirements for the future (Jonkman, Jorissen, Schweckendieck & Van den Bos, 2017). Past flood defence...

PoDeA, Port development Argentina

This report contains the conceptual lay-out for two possible expansions of the port of Bahía Blanca. To determine the best conceptual lay-outs, emphasis is drawn to understand the physical system to determine the effect of the expansion of the port on the natural system. The port of Bahía Blanca is situated at the end of a ria, or tidal basin....

A parametric decision model for navigational lock components: With the Prinses Marijkesluizen as case study

More than 50 locks owned by Rijkswaterstaat need replacement or renovation in the coming 40 years. Due to this fact an opportunity for changing the traditional way of building and maintaining navigational locks has arisen. Because of the replacement/renovation of locks in the coming time, implementing a new owning and building strategy is...

Grass revetment reinforcements: A study into the effectiveness of measures applied during critical conditions.

Reinforcement measures are applied by water boards during critical conditions in an ultimate attempt to prevent flooding. However, the effect of these measures on the reduction in flood risk or failure probability of the flood defence is often unknown. This research focusses on the effectiveness of grass revetment reinforcement measures applied...

Wind Turbines near Flood Defences: Study on the impact craters of falling nacelles hitting a dike

Building wind turbines near flood defences has numerous advantages over other locations on land. The water authorities, which own the land of the flood defence, will only permit the turbines if the flood protection assessment satisfies the safety standard after the wind turbines have been constructed. There are three types of failure of a wind...

Flexible evacuation method: Minimize loss of life probability for a given flood threat

Time-Dependent Capacity of Driven Displacement Piles in Sand

A time-dependent capacity increase has often been observed for driven displacement piles in sand. Long-term bearing capacity increase after dissipation of excess pore water pressure is referred to as set-up. Significant increases in axial capacity have been reported where the rate of set-up varied between 15 and 75% per log cycle of time. <br/>...
