Propagation of tides and similar waves

Development of mathematical methods (digital and analog) for the computation of tides in seas and estuaries. This work is the basis for the numerical tidal computations, as well as the development of the analog computer DELTAR to predict tides in estuaries.

Het deltaplan en zijn verschillende facetten

Bundel met artikelen over de waterloopkundige en waterbouwkundige achtergronden van het Deltaplan. Het artikel van Van Veen gaat in op de wordingsgeschiedenis van het Deltaplan, de plannen van voor 1953 en de analoge wiskundige modellen (deltar). De Vries gaat in op de planvorming en de besluitvorming van de Deltacommissie t.a.v. de...

MSettle Version 8.2 - Embankment Design and Soil Settlement Prediction

This is the user manual for MSetuser manual tle, which is being developed by Delft GeoSystems, a Deltares company. MSettle is a dedicated tool for predicting soil settlements by external loading. MSettle accurately and quickly determines the direct settlement, consolidation and creep along verticals in two-dimensional geometry. GeoDelft has been...

Fast and robust solution methods for the water quality equations

This thesis discusses the use of fast and robust solution methods for advection-dominated advection-diffusion-reaction equations coming from water quality problems. Therefore we look at fluxlimiters by the FCT method in combination with the local-theta approach to increase both the accuracy and the efficiency. The discretized equations (by the...

Combining a Physics-based Model and Spatial Interpolation of Scarce Bed Topography Data in Meandering Alluvial Rivers

All human life is dependent on fresh water and activities related to monitoring its availability have become crucial for financial and survival reasons. Most rivers are being constantly investigated today by both the private and public sector using various means. In advanced countries, the researches cover extensively the riverbed in order to...

Seismic bearing capacity of shallow foundations in Groningen: A method comparison study

The induced earthquakes in the north of the Netherlands cause problems for the shallow foundations. At this moment there is no generally accepted way to deal with these earthquakes. The NPR advises a combination of two methods to calculate the seismic bearing capacity of shallow foundations. In order to find out if this procedure is legitimately...

Redesign of the Solution Algorithms in Wanda

The Wanda software package developed by Deltares can used for simulating both steady state and transient fluid flow in pipeline systems. Steady state simulations are used for initial system design and transient flow simulations are used for doing water hammer analysis in pipeline systems. For both types of simulations a system consisting of both...

Sediment transport during the execution of the pilot nourishment Ameland Inlet: Development of a tool for analysing bathymetric surveys, applied on the pilot nourishment Ameland inlet

Within the KustGenese 2.0 research project a 5Mm3 pilot nourishment is created on the ebb-tidal delta of Ameland. For this thesis I was involved in the parties; Van den Herik, the contractor who executed the work, Deltares and Rijkswaterstaat. A tool is created to quickly analyse new surveys in combination with the ships deposit data. The tool...
