This course is a blended educational experience, meaning that both self-paced modules and instructor led sessions are held. Through a combination of lectures and hands-on exercises, during 3 consecutive interactive sessions, our Delft3D Flexible Mesh – Coastal Hydrodynamic Modelling course introduces grid generation for flexible grids, unique bathymetry interpolation methods, quickly setting...

This paper gives a historical overview of 2D and 3D hydrodynamic modelling in The Netherlands from the 1960s till now. It started in the 1960s with 2D (depth-averaged) shallow sea modelling for practical applications of the Dutch government. The most important application was the Dutch ‘Delta works’ project, which was initiated after the February 1953 flood disaster in The Netherlands. In the...

Storm surges associated with severe tropical cyclones are among the most hazardous and damaging natural disasters to coastal areas. The Gulf of Thailand has been periodically affected by typhoon induced storm surges in the past (e.g. storm Harriet in 1962, storm Gay in 1989 and storm Linda in 1997). Due to increased touristic / economic development and increased population density in...

In this webinar, we will show the processes of making a morphological model of the Rhine Branches in the Netherlands, from the early discussions on the conceptual setup, through the model construction, calibration, until the utilisation in projects and case studies. The Rhine River is considered the backbone of the Northwest European waterways network. All efforts are made to ensure the...

In this webinar we will focus on the continuous development and improvements in the operational tide-surge models of the Northwest European Shelf and in particular the North Sea and adjacent shallow seas and estuaries. For the Netherlands, accurate water-level forecasting in the coastal region is crucial, since large areas of the land lie below sea level. The importance...

Natural phytoplankton communities usually consist of many different species with distinct characteristics. Moreover several species may have a negative impact on the aquatic ecosystem or its user function for instance due to the production of toxins.  The BLOOM phytoplankton model was specifically designed to simulate the competition of functional groups or individual species for...

Deltares has won the IAHR Industry Innovation Award for our Open Source Software initiative. This initiative is contributing to the global application of hydraulic research results.   Given the great speed of scientific production in the field, international co-operation is needed to have synergy. The prize was handed over by the president of the IAHR Roger Falconer; ‘Deltares open source...

Many estuaries worldwide are becoming more urbanised with heavier traffic in the waterways, requiring continuous channel deepening and larger ports, and increasing suspended sediment concentration (SSC). An example of a heavily impacted estuary where SSC levels are rising is the Ems Estuary, located between the Netherlands and Germany. In order to provide larger and larger ships access to...

Two dams on the Elwha River, Washington State, USA trapped over 20 million m3 of mud, sand, and gravel since 1927, reducing downstream sediment fluxes and contributing to erosion of the river’s coastal delta. The removal of the Elwha and Glines Canyon dams, initiated in September 2011, induced massive increases in river sediment supply and provided an unprecedented opportunity to examine the...

The webinar is based on a recently published vision paper that discusses the advances made over the last three decades in coastal sand transport and morphodynamics, and the research needs for the coming decades. The prime focus of the paper is on the relationship between the transport of sand particles and fluid motions in the coastal environment based on laboratory and field...

Van Veen, D. Vatvani, F. Zijl For implementation of a regional Tsunami Early Warning System (EWS) in Sumatra island in Indonesia, a set of detailed and accurate tsunami propagation and...

Special issue: Understanding sediment transport and geomorphic evolution in an estuarine-coastal system: San Francisco Bay The San Francisco Bay Coastal System is a complex marine system with powerful waves and tidal currents, intricate estuarine circulation and sediment transport patterns, and significant anthropogenic influences. The Bay is an urbanized estuary that is impacted by...

On Tuesday, 5 November at the Delft Software Days (DSD2013), Deltares handed out an award to a member of the software community in recognition of his substantial contribution to the open source portal. The software community includes more than 5,300 members. The person who was most active on the Delft3D forum this year was Renan Ribeiro of Tetra Tech in Brazil.   Renan Ribeiro (left)...

It offers 1D2D3D modeling of...

Gerben de Boer (Deltares) will present a new webinar on Wednesday, August 14, 2013 (17:00 CEST) entitled: "Efficient pre- and post-processing in Delft3D using the OpenEarthTools" By popular demand we can finally offer you a live demonstration to start using the OpenEarth tools. Don't miss this opportunity, reserve your webinar seat on the werbinar subpage!

At the closing ceremony of the World Dredging Congress (WODCON XX) on 7 June in Brussels, a paper from Dr. Thijs van Kessel, a senior morphology and sediment researcher with Deltares, was pronounced the 'best paper' of the Congress. The jury praised the originality of his research and the clear presentation of the research data. A total of 120 papers were delivered at the twentieth WODCON. ...
