This paper presents a weighted least squares approach to retrieve aerosol layer height from top-of-atmosphere reflectance measurements in the oxygen A band (758-770g nm) over bright surfaces. A property of the measurement error covariance matrix is discussed, due to which photons travelling from the surface are given a higher preference over...

Retrieving aerosol optical thickness and aerosol layer height over a bright surface from measured top-of-atmosphere reflectance spectrum in the oxygen A band is known to be challenging, often resulting in large errors. In certain atmospheric conditions and viewing geometries, a loss of sensitivity to aerosol optical thickness has been...

On August 25, 2017, Hurricane Harvey made landfall near Rockport, Texas as a Category 4 hurricane with maximum sustained winds of approximately 200 km/hour. Harvey caused severe damages in coastal Texas due to extreme winds and storm surge, but will go down in history for record-setting rainfall totals and flood-related damages. Across large...

Over the past decade, a steep increase in the number of seismic events has been observed in the Groningen gas producing region of the Northern Netherlands. It is generally accepted that these are induced by compaction of the reservoir rock due to extensive field depletion, causing a buildup of strain energy which may be released seismically when...

XBeach is a process-based morphological model that has been used for modelling short term behaviour of beaches and dunes. In the past years interest has been shown by researchers and engineers to use XBeach for longer simulation periods (multiple years). XBeach has multiple modules: stationary mode is often used during calm conditions and...

Coastline regression is a significant threat to many coastal zones. Being able to mitigate the erosion while simultaneously improving nature development is something that is increasingly strived for in coastal projects. This report utilizes the building with nature philosophy to explore integrated solutions for a coastal erosion problem in...

For the fatigue assessment of welded structures, several design methods are described by the design codes of IIW, Eurocode3 and DNV. The relation between the stress range and cycles to failures were derived from experiments: the SN curves. With the increased accessibility of finite element software to engineers, a more flexible approach emerged:...

The Netherlands is a country where people have to live with water, rather than fighting against it. This philosophy often requires interaction between infrastructure and waterways, where (hydraulic) structures are placed close to or even extending in the waterway, introducing the risk of ship collision. What makes this accidental load so...

The Ayeyarwady River is a river with large hydrological variations and an abundance of relatively fine non-cohesive sediment, causing the dynamic behaviour of the river with fast shifting channels. This dynamic behaviour, together with the large hydrological variations, is the source of a frequently flooding river with a moderate navigability....

This work presents a new discrete fracture model, namely the Projection-based Embedded Discrete Fracture Model (pEDFM). Similar to the existing EDFM approach, pEDFM constructs independent grids for the matrix and fracture domains, and delivers strictly conservative velocity fields. However, as a significant step forward, it is able to accurately...

This paper evaluates the impact of reduction of doublet well spacing, below the current West Netherlands Basin standard of 1000 to 1500 m, on the Net Present Value (NPV) and the life time of fluvial Hot Sedimentary Aquifer (HSA) doublets. First, a sensitivity analysis is used to show the possible advantage of such reduction on the NPV. The...

Recent developments in Radio Frequency (800 MHz–1000 MHz) Identification (RFID) devices suggest that it is possible to use them for wireless laboratory measurements of the dielectric coefficients (or compositions) of fluid mixtures with possible spin-off for their use in the petroleum engineering practice. The advantage of RFID devices is...

Coda Wave Interferometry analysis is studied for rocks subjected to brittle deformation which is induced by an Uniaxial Compressive Strength testing machine. Ultrasonic pulses, 1 MHz and 2.25MHz, are sent through rock samples and recorded throughout the loading up-to failure. A novel method is proposed, the rolling cross correlation, which can...

A new flood risk approach for design and testing of primary and secondary flood defence structures in the Netherlands relies on the probability of loss of the water retaining capacity. Determining this probability for levees requires a better understanding of consequences of extreme conditions leading to failure, starting with a study of soil....

As a result of increased economic development in Colombia, the pressure on the natural system has increased. The export of natural resources through international ports at both the Pacific Ocean and Caribbean Sea causes conflicts between infrastructure and the dynamic behaviour of the coastal system. This Master Thesis focusses on the bay...

Weaving sections are frequently applied on Dutch freeways. Guidelines are present for designing those freeway weaving sections. However, the origin of these guidelines is unclear and it is not always possible to apply the guidelines. Dutch road designers and road safety experts are searching for methods to evaluate the safety of a (proposed)...

Fluctuating oil and gas prices, coupled with initiatives toward energy security, drive the global storage market of oil and gas. A tank farm, often referred to as a terminal, is an industrial facility for the storage of the oil and/or petrochemical products. Vopak's biggest terminal, Vopak Terminal Europoort (VTE), has an immense capacity of 25...
