van Ekdom, K. (author)The objective of this research is to contribute to the understanding of the morphological behaviour of a sandy foreshore in the Markermeer, along the Houtribdijk. The research is primarily based on monitoring data obtained from the Building with Nature (EcoShape) project “Pilot Houtribdijk”. The focus is on the morphological development of the...master thesis 2017

van den Bosch, B.A.P. (author)Land reclamations in deltaric areas provide space to meet the demand for a safe place to live and work. Sand, a traditional filling material in some locations is becoming scarcer. An alternative filling material is mud. Mud consists of clay, silt, sand, organic material, water and gas. Therefore, it is a versatile material and difficult to...master thesis 2016

Berkhout, B. (author)River bed degradation is sometimes counteracted with nourishment of sediment material. Numerical models — which include Hirano’s sediment continuity model for mixed-size sediment — can be used to predict the transport of different sediment fractions (the waves due to spatial variations in the grain size distribution of the bed material are here...master thesis 2015

Visser, P. (author)After decades of coastal erosion in the north-west area of the Island of Texel, the shore-normal `Eierlandse Dam` had been built in 1995. The dam, situated in the outer delta of the Eierlandse Gat tidal inlet, resulted in a remarkable short-term morphological development of the adjacent coast. Four years following completion of the dam, large...master thesis 2014

Ekkelenkamp, H.H.M. (author)The study starts with possible working mechanisms of the tubes within the complex beach system. In addition, huge amounts of data are collected which tells us more about the sedimentology of the beach and soil structure. This data is used later on to study influenced beach processes and morphological change. For this study both the beach near...master thesis 2012

Scheel, F. (author)Tidal inlet systems, as found in the Dutch Wadden Sea, often feature both sand and mud. Due to differences in sediment properties, sand and mud particles respond different to identical forcing conditions, like short waves and tidal currents. Because of this, sand and mud can get transported to different locations. This process is referred to by...master thesis 2012

Montserrat Trotsenburg, F. (author)The aim of this thesis was to investigate how (macro)benthic organisms interact with the ecological functioning, erodibility and small- to medium-scale morphodynamics of estuarine intertidal sediment by modulating its composition and/or properties. In these interactions, scale is of great importance for the ecosystem engineers. The changes they...doctoral thesis 2011

Pieterse, J.J. (author)Since the end of 2006 in the Netherlands a test is going on with a passive beach drainage system called Ecobeach. The system consists of vertical draining tubes with a length of 2.0 m called PEMs (Pressure Equalizing Modules). Under the surface level, every 100 m a row of PEMs is installed between the high and low waterline. Ecobeach is a Danish...master thesis 2009

Ravenstijn, E. (author)Bed degradation in a number of Dutch river branches, like the Bovenrijn, can cause various problems in the near future. At low waters the navigation depth at the non-erodible layer near Emmerich can become too small. Other problems could be lower ground water levels and stability of structures in and near the river, like groynes. To diminish...master thesis 2009

Van Damme, M. (author)Extracellular Polymeric Substance is found to be responsible for the stabilizing behaviour of biofilms on sediment, but studies disagree on how this stabilizing effect is achieved and what processes are involved in making an EPS biofilm shear off. This study answers the question how the biofilms achieve the stabilizing effect and what processes...master thesis 2009

Montserrat, F. (author), Van Colen, C. (author), Degraer, S. (author), Ysebaert, T. (author), Herman, P.M.J. (author)We assessed the influence of benthic communities on sediment properties in large defaunation experiments in replicated 16 m2 plots on a tidal flat in the Westerschelde estuary (SW Netherlands). We compared microphytobenthos and benthic macrofauna recovery and recolonisation between control and defaunated sediments during 8 mo following the...journal article 2008

Van Kessel, T. (author)Knowledgeof the yield strength of subaqueous sediment beds is essential to calculate their sensitivity to erosion and failure. Also for dredging operations yield strength is a parameter of the utmost importance. This report describes measurements of the yield strength profiles of cohesive sediment samples with a sounding instrument developed by...report 1996

De Vletter, J. (author)The Hooghly river is situated in West Bengal, a Northeastem state of India. The capital of West Bengal is Calcutta. (See figure 1). The discharge from all the eastem and western tributaries, and from the direct head from the Ganga, flows into the Bay of Bengal through the Hooghly estuary. The Hooghly delta is part of the Indo-Gangetic delta. The...master thesis 1992

Dongeren, A. (author)In this report, a model is derived which simulates the behavior of channels and flats in a tidal basin after a change in the exogenous parameters. In chapter 1, a short introduction is given about the context in which this research has been done. Chapter 2 discusses the general features of the tidal inlet system as well as its formation and...master thesis 1992

Moerwanto, A.S. (author)Sediment transported by natural stream flow has often presented the irrigation and hydropower plant designer with major problems, and measures for solving the sediment problems have been proposed. Most of the proposed sediment exclusion measures have been developed based on certain basic hydraulic principles and experiences gained from field...master thesis 1990
