To cope with the groundwater depletion problem and achieve sustainable groundwater development, groundwater conservation measures and managed aquifer recharge (MAR) have been implemented worldwide. However, knowledge gaps exit how does the aquifer system respond to these interventions differently and if these interventions are adequate to...

The identification of arsenic-contamination hotspots in alluvial aquifers is a global-scale challenge. The collection and inventory of arsenic concentration datasets in the shallow-aquifer domain of affected alluvial basins is a tedious and slow process, given the magnitude of the problem. Recent research demonstrates that oxbow-lake...

In the past, fin-and tube heat exchanger (FTHE) tube pattern ratios have been largely based on ad-hoc design principles. Here, we investigate the optimal tube arrangements for a FTHE with plain fins in marine environments represented by two different air types; one for unfiltered air with high condensation rate and one for clean dry filtered...

Floods are major natural disasters that have considerable consequences worldwide. As the frequency and magnitude of flooding are expected to be affected by ongoing climate change, understanding their past changes is important for developing adequate adaptation measures. However, the limited spatiotemporal coverage of flood gauges hinders...

The Fogera Plain, Ethiopia, is affected by recurrent flooding of the Ribb and Gumara Rivers. A large dam on the Ribb River is under construction for irrigation, but also to reduce flooding. We investigated the effects of the dam on the flood regime of the floodplain wetlands using a combination of hydrodynamic and a rainfall-runoff models....

Recently, implementing steel slag ballast has been proposed as an appropriate material to substitute stone ballast. In this regard, one of the technical concerns is the behavior of steel slag ballast in both time and frequency domains that needs to be assessed, properly. Furthermore, the combination of stone ballast and steel slag is...

Most bridges in the Western European road networks are ageing. The vast majority of about 90% of these bridges have reinforced concrete as a building material. The traffic intensity, as well as the axle, and the average vehicle weight have increased since these structures were opened to traffic. Furthermore, the structural (design) codes have...

This experimental research is focused on fail mechanisms in non-cohesive soil beneath the jet with a Jet Erosion Test(JET). A vertical plain jet impinges fluid to a sand bed, which causes zero shear stress beneath the jet averaged over time. Many erosion theories would say that no pick-up happen at that point. <br/><br/>E_c=u/(√(H⁄d) √(ΔgD50 ))...

The first part of this thesis elaborates on two numerical models of different levels of comprehensiveness of a Laval rotor on plain journal bearings. These models are compared to an experiment, capable of rotating at 60 krpm, also devised in this research. Reasonable correlation in terms of whirl and whip behavior has been found. In the second...

Assessment of the capacity of the existing infrastructures has become more relevant in the recent years. With regard to the concrete bridges, the shear capacity of a large amount of existing concrete slab bridges reinforced with plain (smooth) bars are of concern. However, it was argued that the shear formula that is currently adapted in the...

A large number of existing reinforced concrete solid slab bridges in the Netherlands are found to be insufficient for shear upon assessment. However, research has shown additional sources of capacity in slab bridges, increasing their total capacity. Previous testing was limited to half-scale slab specimens cast in the laboratory. To study the...

Journal bearings are used to support rotors in a wide range of applications. In order to ensure reliable operation, accurate analyses of these rotor-bearing systems are crucial. Coupled analysis of the rotor and the journal bearing is essential in the case that the rotor is flexible. The accuracy of prediction of the model at hand depends on its...

Bihar is a densely populated area located in the Middle Ganga Plain (MGP) in India. The Ganges' sinuous nature in the MGP created a vast amount of point bar structures within the floodplain. In 2003 it was discovered that high arsenic concentrations are present in the shallow groundwater aquifers, especially in the elevated point bars. According...

Flood risk (defined as a result of flood probability and potential damage) along Rhine and Meuse rivers is expected to increase in two ways: A. Climate change will cause a significant increase in the probability of extreme floods (according to a majority of climate change scenarios). B. The potential damage of floods (the level of investments in...

In the coming years decision makers are confronted with the question how to combine aims for sustainable flood protection and floodplain rehabilitation in the best possible way. Both topics deal with spatial planning aspects and dimensions of measures. On this basis an evaluation method was developed within the IRMA/SPONGE project INTERMEUSE and...

Many important developments are currently taking place in the area of flood risk management in Europe. The IRMA-SPONGE Umbrella Program aims to contribute to these developments by co-ordinating and integrating 13 research projects, dealing with many aspects of flood risk management along the rivers Rhine and Meuse, in such a way that the output...

In dit afstudeerproject wordt met behulp van een fysisch model onderzoek gedaan naar de uitwisselingsprocessen die bij hoogwater optreden tussen uiterwaard en hoofdgeul van een rivier. Dit afstudeerproject geeft daarmee een vervolg aan het door Van Prooijen [19] opgezette onderzoek naar grootschalige horizontale wervels in ondiepe...

Bij overstroomde kribben in een rivier met uiterwaard zijn grootschalige horizontale wervels te verwachten. Het tijdsgemiddelde langssnelheidsprofiel in dwarsrichting is bepalend voor het ontstaan van grootschalige wervels. In het kribvak vindt een grote richtingsvariatie in ruimte en tijd plaats. Deze variatie zorgt voor een grote uitwisseling...
