Olij, D.J.C. (author)In this thesis 6 wave climate reduction methods are described and evaluated. Of these methods, 3 are commonly used in literature and 3 are machine learning methods that are adjusted so that they can be used for the reduction of a wave climate. The evaluation is executed with the use of a Delft3D model of the coast of Durban, South Africa.master thesis 2015

Van de Waal, R. (author)The Dutch Western Wadden Sea, comprising the basins of Texel, Eierlandse Gat and Vlie, suffers a shortage of sediments. This implies that sediment is imported into the basins. The influence of the main forcing agents on the sediment transport is investigated. These forcing agents are the tide, waves and wind. In case of the wind forcing, both...master thesis 2006

Van der Kaaij, T. (author), Nieuwjaar, M.W.C. (author)In many coastal, engineering problems the sediment transport plays a part. A transport gradient causes accretion or erosion. Various models, such as that of Bijker, Engelund and Hansen (van de Graaff and van Overeem, 1979) and Nielsen (1985) are available to estimate the sediment transport rate if the hydraulic and environmental conditions (wave...master thesis 1987

Nijhuis, Loes (author)The Rhine-Meuse estuary is part of the Southwestern Delta area in the Netherlands. The nature present in the estuary suffered a great impact due to urbanization, as a natural delta transformed into an industrialized river, mainly due to port activities. Various parties decided to collaborate in order to return the tidal nature in the Rhine Meuse...master thesis 2021

Veuger, A. (author)The area of interest in this study is the closed part of the Holland coast. This is the coastal stretch from Den Helder to Hoek van Holland. Here the coast is not interrupted by tidal inlets like at the Waddeneilanden or Zeeland.Due to erosion and accretion the coast is not always stable. Many investigations have been done on these phenomena...master thesis 2001

Nap, E.N. (author), Van Kampen, H.F.A. (author)Investigation to sediment transport rate in case of waves and currents, tests executed in the wave-current flume of the laboratory of Fluid mechanics of TU Delft. Sediment transport was measured using sand of 100 micron; comparison to similar tests with 200 micron sand.master thesis 1988

Borsje, Ruben (author)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...master thesis 2019

Van Noort, J.C. (author)Rip currents are narrow and intense, offshore directed flows in the nearshore zone. A rip current is able to transport a considerable amount of water and sediment seaward and may dominate the morphological exchange between surfzone and the offshore. Rip currents are often located nearby lateral boundaries that obstruct the longshore current, but...master thesis 1997

Havinga, F.J. (author)The present report contains a description of an experimental program, as a follow up of experiments by v.d. Kaaij and Nieuwjaar in 1986, and Nap and Van Kampen in 1987. As in the second study, in the present study a particle sand diameter of D50 = 100 mu was used, so that the experiments of Nap and Van Kampen will be referred as "the earlier 100...master thesis 1992

Janssen, C.M. (author)Cross-shore sediment transport is an important phenomenon in coastal engineering, which mainly accounts for the short-term changes in the coastline. To study on- and offshore transport the evolution of the beach profile is considered. For investigation of the beach profile small-scale physical models are often used. A problem in using a physical...master thesis 1993

Eerkens, J.W. (author)In one-dimensional river modelling it is common to schematise the cross-section into a rectangular cross-section with a constant width. If a quasi-steady flow is assumed, the equilibrium longitudinal profile is known and unique: the bottom slope is constant and equals the water surface slope. However, numerical calculations at DELFT HYDRAULICS...master thesis 1996

Kok, Emma (author)In the Waal bed degradation occurs, which is mainly induced by a large number of river regulations measures done in the past. Rijkswaterstaat develops possible measures and new techniques to stop riverbed erosion and/or mitigate the negative effects. One of the possible new techniques to reduce riverbed erosion locally is groyne field...master thesis 2020

Hop, M. (author)The Rhine ROFI ( region of freshwater influence) is a dynamic area where various processes and timescales come together. Research has shown that stratification caused by the freshwater outflow of the Rhine alters the tidal currents in front of the Dutch coast. In the case of the Netherlands the tide behaves like a kelvin wave, which causes...master thesis 2017

Sloff, C.J. (author)The rivers on the slopes of the Kelud volcano in Indonesia are marked by steep slopes and fine sediment. Therefore often supercritical flow and large sediment transports occur. In this exploratory study a mathematical model has been developed for this type of rivers. The properties of this model are examined with an analysis of the...master thesis 1990

Palaiogianni, N. (author)The current report aims to understand the hydro- and morphodynamic response of the Western Scheldt in a large sediment dumping operation. This study investigates the estuary’s response to sediment dumping in the Everingen channel area, which is located in the middle of the Scheldt Estuary, The Netherlands. Furthermore, it studies whether these...master thesis 2015

Martens, D. (author)East Coast Park is a 15 km long coastal park along the southeast coast of Singapore. It is built on entirely reclaimed land and comprises a sandy shoreline. The beaches along this shoreline are formed due to the implementation of anthropogenic structures all along this stretch of coast through so-called headland control. These structures were...master thesis 2013

Umapathy, S. (author)The study focuses on the impact of human interventions on the natural behaviour of estuaries in response to sea-level rise. In particular it focuses on the affect of managed realignment on the critical sea level rise (SLRcrit) for the Poole Harbour.

Hulsman, P. (author)The Mara River originates in Kenya in the Mau Escarpment and flows through the Serengeti ecosystem into Lake Victoria in Tanzania; in total it is about 395 km long. In this river, human interventions have led to increased of agricultural areas. As a result, increased fast runoff and top soil erosion is expected. Consequently, more sediments is...master thesis 2015

Bakker, Floor (author)To exploit its socio-economic functions, engineering measures are regularly applied in estuaries. Estuaries are, however, known to be very complex systems. Stemming from this complexity is the generation of a so-called estuarine turbidity maximum (ETM), which poses great siltation problems to the engineering measures. An engineering measure,...master thesis 2020

van Weerdenburg, Roy (author)Considering scenarios of sea level rise, the sediment budget of the Wadden Sea is of interest for both coastal safety and for the maintenance of values of this unique environment. Sand nourishments are foreseen on the ebb-tidal deltas of the Wadden Sea to increase the sediment budget, which requires us to predict the fate of the nourishment....master thesis 2019
