Zhu, Chunyan (author), Zhang, Yuning (author), van Maren, D.S. (author), Xie, Weiming (author), Guo, Leicheng (author), Wang, Xianye (author), He, Qing (author)The sediment load in the Yangtze River downstream of the Three Gorges Dam (TGD) has substantially declined in recent decades. The decrease is more profound below the TGD, e.g., a 97% decrease at Yichang, compared with that at the delta apex, 1200 km downstream, e.g., a 75% decrease, implying along-river sediment recovery. Two large river...journal article 2023

Zhu, C. (author), van Maren, D.S. (author), Guo, Leicheng (author), He, Qing (author), Wang, Zhengbing (author)A decline of the fluvial sediment supply leads to coastal erosion and land loss. However, the fluvial sediment load may influence not only coastal morphodynamics but also estuarine hydrodynamics and associated saltwater intrusion. Previous studies revealed that suspended sediments influence estuarine hydrodynamics through various flow...journal article 2023

Bles, Matthijs (author)Mangroves are productive ecosystems. Degradation of mangroves has been observed since the 1970s, due to a variety of reasons. Successful rehabilitation focuses on restoring conditions suitable for mangroves. Sediment availability has been shown to positively impact mangrove growth. Therefore, it can likely play a role in mangrove rehabilitation....master thesis 2022

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

Hoonhout, B.M. (author), de Vries, S. (author)Mega nourishments are a novel approach to stimulating coastal safety and resilience. Mega nourishments are intended to spread along the coast on a decadal time scale by natural sediment transport processes with a minimum of intrusion into the natural coastal system. The supratidal morphodynamic behaviour of mega nourishments is not well...journal article 2019

Mobron, Nadia (author)Phenomena like urbanization and climate change will increase flooding problems, making it clear that more research and investments are needed in sewer systems to improve urban flood prevention. This research was done to determine factors influencing the sediment load to gully pots. It was assumed that in the measurement period, the retaining...student report 2018

Zhao, Jie (author), Guo, Leicheng (author), He, Qing (author), Wang, Zhengbing (author), van Maren, D.S. (author), Wang, X. (author)Examination of large scale, alluvial estuarine morphology and associated time evolution is of particular importance regarding management of channel navigability, ecosystem, etc. In this work, we analyze morphological evolution and changes of the channel-shoal system in the Changjiang Estuary, a river- and tide-controlled coastal plain estuary,...journal article 2018

Gong, Yichuan (author)This thesis explores the nature of coastal dune behavior and the role of sediment supply in the aeolian system. The first part of the thesis conducts a data analysis based on the Dutch JARKUS dataset, which provides yearly measured profiles along the Dutch coast. A series of parameters derived from the profile measurements have been used to...master thesis 2017

Papatrecha, Natalia (author)Growing interest has been expressed the last decades regarding the Late Cenozoic, gas-bearing sediments of Southern North Sea Basin. Comprising the shallow subsurface of the Dutch offshore sector, these sediments have<br/>been deposited by Eridanos fluvio-deltaic system, draining the Fennoscandian and Baltic shield through the present Baltic Sea...master thesis 2017

Wittebrood, M. (author)In 2014-2015 the coastal stretch between Petten and Camperduin was strengthened by using 35 million m3 of sand. At the seaward side of the Hondbossche & Pettermer sea defence a beach and dune system was built which is called the ‘Hondsbossche Dunes’. The old sea dike has disappeared behind the new dunes and is no longer an active part of the...master thesis 2017

Hoonhout, B.M. (author), de Vries, S. (author)Mega nourishments are intended to enhance growth and resilience of coastal dunes on medium to long time scales by stimulation of natural sediment transport processes. The growth and resilience of coastal dunes largely depends on the presence of a continuous supply of aeolian sediment. A recent example of a mega nourishment is the 21 Mm<sup>3<...journal article 2017

Hoonhout, B.M. (author), de Vries, S. (author)Spatial variations in aeolian sediment transport were measured at the Sand Motor mega nourishment in The Netherlands during a six week field campaign in the fall of 2014. A consistent significant increase in sediment transport in downwind direction (positive gradient) was measured over the intertidal beach area, indicating that the intertidal...journal article 2017

Lipus, M.P. (author)Process-based numerical simulations in river delta modelling have demonstrated the importance of hydraulic and sedimentary forcing mechanisms on delta morphodynamics. Insights of these simulations on deltaic systems have a high potential to improve reservoir predictions in the industry. However, detailed morphological studies are typically...master thesis 2015

Orru, C. (author), Chavarrias Borras, V. (author), Ferrara, V. (author), Stecca, G. (author), Blom, A. (author)A flume experiment was conducted to examine the evolution of a sand-gravel reach under a lack of sediment supply. A bed composed of a bimodal sediment mixture was installed with a uniform slope and an gradual fining pattern. At the upstream end of the flume the initial bed consisted of 100% gravel, which decreased stepwise (10% steps) in...conference paper 2015

Chen, F. (author)Deltaic reservoirs are of great significance in both exploration and production of oil & gas and they have aroused increasing interest during the recent years. Coastal engineering deals with sediment transport on a millisecond and micron scale, while geology deals with sequence stratigraphy on a millenary and 10-100 km scale. However, relatively...master thesis 2014

Busch, S.P. (author)The Panther Tongue is a fluvio-deltaic parasequence in the lower part of the Star Point Sandstone formation in the Wasatch Plateau, central Utah, deposited during the late Cretaceous period. The sedimentology of the Panther Tongue and adjacent beach ridges parasequence has been extensively described by Hwang & Heller (2002) and Hampson et al. ...bachelor thesis 2013

Stark, J. (author)This is a numerical modelling study on the impact of dredging and disposal activities on the long-term morphological development of the Columbia River mouth (MCR). Dredging activities removed 120 Mm3 of sand from the MCR during the studied interval between 1958 and 1999. Only one-third of this volume was disposed in the active littoral zone....master thesis 2012

Brommer, M.B. (author), Weltje, G.J. (author), Trincardi, F. (author)Reconstruction of sediment supply is hampered by the incompleteness of the stratigraphic record. This problem may be partly circumvented by studying mass accumulation rates in closed systems, i.e., basins in which no sediment has bypassed the site of deposition over the time interval of interest. We present time-averaged basin-wide mass...journal article 2009
