Dolgov, Alexey (author)
Cyclic wetting and drying impact the integrity of cohesive clay materials in geotechnical engineering applications. Boom Clay, frequently used in erosion protective layers, presents a critical case study due to its widespread application and the environmental conditions it endures. This research delves into the effects of repeated wetting and...

Rain erosion of leading edges in wind turbines caused by high-velocity droplet impacts is one of the current problems in wind energy that affects their energy production and maintenance costs. The most widespread solution for this problem is the application of viscoelastic coatings (generally, polyurethane) along the leading edge of the wind...

In this study, the excavation process of a low pressure vertical impinging jet in cohesive soil has been investigated. Mass flow excavation is a hydraulic, low pressure, subsea excavation method whereby a large volume flow is applied to the seabed through which the seabed is eroded, and the soil is transported. <br/>The erosion process of a...

Demak is a regency within the province of Central Java, Indonesia, with a mud-mangrove coast bordering the Java Sea. The region is facing a rapid retreat of the coastline, threatening the livelihood of a large part of the population. The main cause of the erosion is the deforestation of the green belt of mangroves. This has disturbed the...

In large braided rivers, river training is often required to protect the banks against erosion, to improve navigability and for land reclamation. Closing one of the channels is a promising option to achieve these goals. However, there is a lack of systematic research on channel closures and no guidelines for their use exist. In the few...

The stability of subaqueous slopes is often studied to determine the probability of failure of hydraulic structures. Slope failures have been widely studied to increase the understanding of this complex failure mechanism. However, after a failure it is often hard to figure out the type of failure mechanism: static liquefaction or breach flow....

Pipelines and cables on the sea bottom are usually protected by a cover of dumped rock. In case of maintenance or removal works, this cover has to be removed in order to expose the pipeline. This removal can be performed by means of a mass flow excavation process, created with a submerged jet flow. However, the exact erosion processes of a...

How to, a landscape architect, design with coastal natural processes? Coastal areas have stronger and more fluctuating natural variables than many sites in more sheltered areas. Understanding the past, present, and future form of these processes will allow the designer to shape a form and program that works with the site-specific...

Sand dikes have a sand core and a clay layer to protect the core against erosion. It is not unlikely that this layer fails due to several failure mechanisms, exposing the sand core to water. This can be catastrophically when water is overtopping the dike. In case the protective cover fails, water can flow over the core and erode the sand,...

The Afsluitdijk is unable to withstand the future conditions that belong to an annual probability of occurrence of 1/10 000 per year for water level and wave conditions. Solution of Rijkswaterstaat is to strengthen the dike according to the principle of the wave overtopping resilient dike (NL: Overslagbestendige dijk). Therefore the Afsluitdijk...

CityGML is a standardized data format used to store the semantic information and geometries of buildings and other object classes of 3D city models. The Level of Detail of current state of the art city models (LoD2) is not sufficient for accurate environmental simulations like noise, the solar potential of windows and other types of analyses. An...

The city of Itajaí is located in the province of Santa Catharina in Brazil. The people of Itajaí have been coping with flood risk for the past decades. During normal conditions the Itajaí-Açu River is a rather calm river that is used for navigation and the harbour area. Recovering from the past two floods in 2008 and 2011 have cost more than...

In this study, a probabilistic vulnerability assessment to the impact of storms in the coast of Thrace, Greece was carried out. To this end, the methodology presented by Bosom and Jiménez (2011) has been applied with some modifications. The introduced modifications, for this work, were the use of a different run-up model to deal with the...

This research focusses on the behaviour of fine particles which pass through the armour layer of bed material of the upper and middle reaches of a river. When the fine particles are entrained in the armour layer, it is described as ‘winnowing’ or vertical entrainment. A river bed generally consists of a coarse surface layer, which is the...

This master thesis aims to determine the best design option and the feasibility of an artificial sandy beach along the Old Boulevard of Batumi, Georgia. The coastline south of Batumi is affected by erosion problems. The coastal stretch between the port in the north and the Chorokhi River south of Batumi should be protected. In 2010 Alkyon...

Software design erosion is a well known process; however, once it becomes noticeable it may already have progressed so far that repairing it is difficult and costly. Design conformance assessment techniques can help developers to detect – and mitigate – the effects of design erosion, before they cause problems to the long-term maintainability of...

Cold Heavy Oil Production with Sand (CHOPS) is a production method to produce heavy oil (>100 cP). It is mainly applied onshore Canada in unconsolidated sand reservoirs. Different theories exist about how the erosion process takes place inside the reservoir. This research project focused on the influence of the grain stress on the sand erosion...

Due to the closure of the Haringvliet in 1970 as part of the Delta works and the opening of the Beerdam in 1997, the course of the tidal flow in the Rhine-Meuse delta has changed. The tidal flow from and towards the Haringvliet is now completely taking place through the branches that connect the Haringvliet with the Nieuwe Maas and Nieuwe...

The Langmann reservoir is part of the hydropower system in the river Teigitsch and in the reservoir loss of storage volume occurs. The reservoir was therefore flushed, but recently no permission is granted. The reason is the high sediment concentrations that have negative effects on the downstream region. An optimization of the flushing...
