Delft3D Suite

3D/2D modelling suite for integral water solutions

Wind, waves and currents shape our coasts. Climate change and rising sea levels add further to this pressure. To enable us to live safely along our shores, we need effective coastal and marine management. Moreover, these coastal processes do not present the only threat. We must also protect ourselves against excess river water, while on the other hand we need that water for transport, irrigation, energy, cooling, recreation, environmental protection and as a source of drinking water. Consequently, design and management procedures become more complex and require an integrated approach. Usually, a range of conflicting aspects needs to be evaluated and it is crucial that the compound impact may be surveyed from any desired viewpoint also in terms of time and space.

In response to this challenge, Deltares has developed powerful modelling suite software called Delft3D, focusing primarily on application in the free surface water environment.

General

Delft3D is a flexible integrated modelling suite, which simulates two-dimensional (in either the horizontal or a vertical plane) and three-dimensional flow, sediment transport and morphology, waves, water quality and ecology and is capable of handling the interactions between these processes. The suite is designed for use by domain experts and non-experts alike, which may range from consultants and engineers or contractors, to regulators and government officials, all of whom are active in one or more of the stages of the design, implementation and management cycle.

The current version of Delft3D is version 4.00.02.

Features

Some of the typical key features of Delft3D are:

  • the suite gives direct access to state-of-the-art process knowledge, accumulated and developed at one of the world’s most renowned hydraulic institutes
  • the Graphical User Interface (GUI) is one of the most user-friendly in the market
  • all programmes show a high degree of integration and inter-operability.

3D/2D software

Natural phenomena have inherent spatial characteristics, i.e. variations may occur in the two horizontal directions and along the vertical axis. Likewise, elementary natural processes often require a three-dimensional (3D) description, are time dependent and mostly interrelated. For instance, local hydrodynamic conditions determine the local sediment transport rates. However, the gradients of those rates determine the bathymetry, which in turn affects the hydrodynamic basis of the process. Appreciating nature’s complexity, we at Deltares have always incorporated these interrelationships into our work. And this notion has been a crucial design aspect in the development of reliable, modular 3D/2D software.

Programmes

Delft3D allows you to simulate the interaction of water, sediment, ecology and water quality in time and space. The suite is mostly used for the modelling of natural environments like coastal, river and estuarine areas, but it is equally suitable for more artificial environments like harbours, locks, etc. Delft3D consists of a number of well-tested and validated programmes, which are linked to and integrated with one-another. These programmes are further described separately hereafter:

Graphical User Interface

The Graphical User Interface (GUI) is one of the most user-friendly in the market. Under the umbrella of this GUI, the programmes combine to form an exceptionally versatile, powerful and easy-to-use suite. The GUI allows the user to visualize model input, reference data and simulation results as time series and animations of one-, two- and three-dimensional data sets. The moving image of the flows in and out of an estuary, for instance, can be observed and examined in gradual, fast forward and fast backward mode. The user can also gather a wide, overhead perspective of his entire system or, by contrast, zoom in on a site of particular relevance or difficulty.

Delft3D is open to various data visualizations. One of the most powerful tools is the option to export data to Google Earth.

Validation

The validation of a modelling system such as Delft3D requires continuous attention. Even though the individual programmes of the suite have been thoroughly tested during their development, the suite as a whole requires intensive testing and also validation. To this end, a regular programme has been established and tests of many of the most likely combinations are continually performed. As a policy, new versions are released only after an extensive beta testing period, to ensure that our users are provided with stable and validated products.

Service packages

Deltares offers high quality services to consultancy firms, governmental organizations, universities and research institutes worldwide.

Several Delft3D service packages, including fully validated high quality Delft3D distributions, are available to suit your specific needs!

Designed with you in mind, they offer you your requested level of convenience.

Support desk

The Delft3D support desk is the user’s instantly accessible contact point for all questions and problems concerning the software. The support team answers the majority of questions instantly or ensures that a timely reply is given by one of the other Delft3D team members. All incoming queries on the programmes, current or future performance, are recorded in our professional issue tracker system. This system is an important instrument in the realisation of improvements to the programmes, the manuals and the Deltares Academy training courses. New versions of Delft3D will be released once a year to all users, as part of their service package.

Users meetings

Deltares organizes an annual international Delft3D users meeting. Several smaller Delft3D users meetings are organized at international conferences worldwide. These are excellent venues for receiving updates on the latest developments and for meeting other Delft3D users.
