    Eindevaluatie pilot Langsdammen in de Waal : morphology and maintenance

    River interventions such as the replacement of groynes by longitudinal training walls have morphological effects on different scales. Effects on the smallest scales occur almost immediately whereas effects on the largest scales manifest themselves only after decades. As discharges vary, morphological effects keep fluctuating even in the long term…

    Techniques for monitoring of benthic primary production : 21 december 2021

    This document presents a state-of-the-art review of methods to quantify benthic primary production in estuaries. The advantages and disadvantages of each method are discussed, including their assumptions and uncertainties in measurements. The review includes field and remote sensing measurement techniques. The review is intended to select a…

    Development of sixth generation model schematisation 3D D-Water Quality Veerse Meer : model set-up and calibration

    Recent water quality problems in the Veerse Meer have renewed efforts to develop modelling tools for the lake. In the context of setting up the new sixth-generation models for Rijkswaterstaat, a 3D D-Water Quality model of the Veerse Meer including eutrophication parameters, dissolved oxygen, and related water quality processes has been developed…

    10-years evaluation of the Sand Motor : results of the Monitoring- and Evaluation Program (MEP) for the period 2011 to 2021

    In 2011 the large-scale sand nourishment ‘The Sand Motor’ was constructed (21.5 million m3) with the aim of gaining experience with innovative nourishments that combine recreational, natural and coastal maintenance functions and strengthen the Delfland coast. Unique about the Sand Motor is that it can freely reshape over time as a result of…

    Installation of heating pipelines by shallow drilling : feasibility of the E-power method

    The so called E-Power Pipe technique is a trenchless method which was developed for the installation of underground cables in sleeve pipes. This trenchless technique for shallow drilling and pipeline installation can be used for the installation of large diameters transport heating pipelines. Modification of the technique is necessary to enlarge…

    Detecting floating plastics using a high-frequency X-band radar : a feasibility study on unconventional monitoring techniques for the detection of plastics

    Ship-based X-band radar was tested for the detection of floating plastics. Plastic items are likely to a have a different radar reflection than items of other materials with the same size above the water, since they have different dielectric constants. Three measurement campaigns were carried out in the Rhine-Meuse Delta, revealing its potential…

    Coherent assessment framework for eutrophication : model results Deltares

    This report describes the results of the modelling work done by Deltares in the framework of the OSPAR Intersessional Correspondence Group on Ecosystem Modelling (ICG-EMO). In this group, an ensemble model approach was started in 2020, with the aim to simulate the effects of anthropogenic nutrient loads on nutrient and chlorophyll concentrations…

    Characteristic values of soil properties in Dutch codes of practice : theoretical backgrounds and assumptions

    Soil properties usually show significant uncertainty due to a combination of spatial variability, limited availability of measurements and other sources of uncertainty. Most modern design codes are based on Load and Resistance Factor Design. In these codes, uncertainties in soil properties are covered by design values of geotechnical parameters,…

    Modelling morphodynamics in the presence of immobile sediment : model testing and sensitivity analysis

    For a better management of the river system, Rijkswaterstaat is interested in improving the tools available for predicting morphodynamic changes. As such, an attention point is prediction of the formation and break-up of coarse layers. A new modelling concept (the HANNEKE model) was devised that is capable of better capturing the transport of…

    Modelling seaweed cultivation on the Dutch continental shelf

    In this study we present a few hypothetical scenarios and assess the potential effects of seaweed cultivation layouts on regional and system scale trophic state parameters. We focus on phytoplankton primary production, as the keystone of the ecosystem. Nutrient concentrations are investigated as well, essentially to support our understanding of…

    Aquathermie configuraties : overzicht TEO, TED en TEA door middel van factsheets, kostenkentallen en beslisbomen

    Bij alle technieken van aquathermie wordt er warmte of koude gewonnen uit water. Het water wordt langs een warmtewisselaar geleid waarna het weer wordt geloosd. Als onderdeel van het WarmingUP onderzoeksprogramma (project 3C) zijn er overzichten gemaakt van de verschillende configuraties van aquathermie: TEO (thermische energie uit…
