The phreatic surface is an important factor of influence on the stability and therefore the safety of regional flood defences. For stability calculations usually a schematisation of the phreatic surface is used, based on the geometry of the flood defence and the water levels. The influence of precipitation and evapotranspiration is not...

This study investigates the many dynamics of the Manyame Catchment and comes up with recommendations on how to adapt or become more resilient to the risks at hand. The bad politics and forthcoming economic situation of Zimbabwe has led to instability and dramatic inflation over the last decade. This has resulted in a terrible investment climate,...

Vietnam is one of the five countries that is severely affected by the consequences of climate change. The extreme weather conditions and the increase of the sea level results in floods in the Mekong Delta, located in the South of Vietnam. Can Tho city, found in the heart of the Mekong Delta, is one of the cities that copes with water related...

The Netherlands has always been in close proximity to water, whether its rivers or the sea. This proximity to water and the need for land to settle and farm, led to vast amounts of land reclamation by constructing dykes along the water features to prevent flooding of the new earned land. This newly reclaimed land started to subside over the...

From the 3500 kilometers of primary flood defenses in the Netherlands, a third does not comply with the current standards. As a result, over 700 kilometers will be strengthened in the upcoming years. Traditional strengthening of dikes consists of strengthening with soil and requires space that is often not available. Further strengthening of...

In this additional thesis a 2D urban flood model in the downtown area of Shanghai was investigated. Therefore a numerical model of Delft3D flexible mesh (DFM) was used. Since the model was investigated from scratch, a lot of data analysis and pre-processing was required to have reasonable input data. As input data a surface elevation map, a map...

The design proposal is situated along the edge of the city of Strasbourg, the design deals with a existing flooding problem in the area that currently limits the development of the area. The building looks at providing a new scenic route that crosses through a multitude of different landscapes and elevations. The elevated walkway is meant to...

This thesis adopt existing methodologies for flood-risk assessment in other civil infrastructure (such as dams or urban flooding) and apply them in road type infrastructure in order to quantitatively assess flood vulnerability and risk in project locations where historical closure data is not available and the complex global network-approach...

The summer and autumn of 2018 showed the negative effects of both low-flow conditions and bed degradation over the last century on the river functions of the Dutch Rhine. These resulted in record-breaking water levels, extreme low navigation depth and subsequently nautical problems. As climate change will increase the inter-annual variability of...

A large part of the world population lives in deltas or in the vicinity of a river which provides many advantages, such as access to transportation, food and drinking water. Inundating floodplains are a natural and recurring phenomenon which is for instance a way to irrigate soils, but drawbacks occur when people or infrastructure are harmed by ...

Fluvial flooding is a recurring phenomenon in Rwanda due to a combination of climate, topography and human interventions. This poses a hazard to human lives and infrastructure, particularly in low-lying areas adjacent to major rivers. An example of such areas is the Masaka wetland, located in the southern edge of the capital Kigali along the...

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...

After a waterflood the oil saturation is (close to) the irreducible oil saturation, wherein oil in a porous medium is dispersed over the pore network in unconnected droplets due to snap off. In a chemical flood, the surfactant reduces oil-water interfacial tension and liberates the trapped oil droplets. These mobilised droplets coalesce into a...

In the far south of the Netherlands, the erratic river Meuse flows through the landscape. It recently flooded twice in the 1990s, causing much economical damage. Emergency measures, such as a demountable flood wall, were taken to prevent future flooding. And while this solution was to the liking of the inhabitants, the update in the flood safety...

"Floating for Health" is a project of the Architectural Engineering graduation studio at the Delft university of Technology. This research and design project explores the problems of rural flood-prone areas in low-income regions and proposes a solution for the lack of healthcare facilities. The context that has been chosen is the region of West...

The United States of America have a safety standard for flood protection of 1/100 year. However the flood protections in the Washington D.C. do not comply with this requirement. During this study the levees in Washington D.C. area were analysed and it was found, that in order to comply with the 1/100 safety standard the levees in the...

Plastic debris in water systems form a major problem for our ecosystem because it is extremely persistent in the environment and the global plastic production is still increasing without adequate measures to prevent pollution. Apart from the importance of reducing the amount of plastic entering the ocean, clearing the rivers from debris is...

At the Shonai River around Nagoya, Japan, several flood related problems occur. These problems occur at different locations, each with its own problems or limitations. The desired safety level as requested by the government is that the river should be able to have a discharge which has a probability of failure of once in 200 years. At many...

In the past decades, several EOR (Enhanced Oil Recovery) techniques have been developed to increase the amount of oil recoverable from a reservoir. Among these techniques, polymer flooding consists in the injection of a solution of water and polymer into the reservoir, and it is performed in order to lower the mobility of injected water. A...
