DELTARES, SEPTEMBER 2014

Delft
Software Days
At the ‘International Seminar
on Paste and Thickened
Tailings’ (Paste), which took
place in Vancouver in June,
Deltares teamed up with the
Delft University of Technology
and Barr Engineering to
present the latest results of the
study of how slurry settles.
Slurries aremixtures of soil
and water. Many features of
slurry transport are still poorly
understood. For example, it
is unclear where in the flow
the behaviour of themixture
fundamentally changes nature
and when themixture settles.
This is important because the
settlement of themixture can
lead to blockages. Deltares,
Delft University of Technology
and Barr Engineering have
been studying this extensively
in recent years and established
a clearer picture of what
happens.
This was the seventeenth
edition of the ‘Paste’
seminar, where scientists
and consultants in the field
of slurry exchange their
knowledge with commercial
companies and organisations
that work with slurry.
iMOD
open
source
Since mid-June, the source code for
iMOD has been publicly available.
iMOD is a fast and user-friendly
graphic user interface for groundwater
modelling using the computational
cores MODFLOW, MT3DMS and
SEAWAT. The transfer of iMOD to open
source represents the next step in the
Deltares open-source policy. Deltares
has made the source code available to
encourage collaboration and to further
ongoing joint development. The iMOD
source code can be downloaded from

The new Deltares hydro software, and particularly
Delft3D Flexible Mesh, will be the focus of
considerable attention at the Delft Software Days
(DSD-INT 2014), where the results from a range
of pilot studies conducted over the past year will
be presented. For example, the new software
was used to model the lagoon of Venice and
San Francisco Bay. The aim of the pilot studies
is to introduce outside organisations to the
new software and to conduct tests to see where
improvements or changes are needed. More pilot
studies will be carried out in the course of 2014
and 2015. Delft3D Flexible Mesh will go onto the
market in 2015.
The Deltares hydro software has been leading
the way for decades and it is used in more than
140 countries throughout the world by water
managers, modellers, business, and knowledge
and research institutes.
A number of packages have, since 2011, been
integrated and undergone a fundamental
technological overhaul as part of the ‘Next
Generation Hydro Software’ project. The strength
of the new software is the new Delft3D
computational core D-Flow Flexible Mesh.
Edward Melger, the product manager at the
Deltares Software Centre: ‘It works very fast
with the flexible mesh and it can be used to
establish a detailed mesh which provides an
accurate representation of all the characteristics
of the water system, resulting in a highly realistic
picture. The new software is particularly suitable
for integrated studies of catchments.’
The Delft Software Days this year will be from
27 October to 7 November. This event is the
place for developers and users of Delft software
to exchange expertise and experience. Last year,
there were visitors from almost 40 countries.
There are numerous conferences, workshops, user
meetings, courses and presentations about the
software developed by Deltares, Delft University
of Technology and UNESCO-IHE. The Delft open
source software community now has 10,000+
members throughout the world and it is growing
fast. The DSD-INT 2014 have been organised to
support the open source community and they
are important in terms of furthering links with
universities, research institutes, government
authorities and business. The DSD-INT 2014
will take place on the Deltares campus in Delft.

How can we make cities resilient
to floods, extreme precipitation,
drought and heat? There has
been an enormous research effort
in this area in recent years and
whole books have been filled with
descriptions of possible measures.
The Climate App, a new free
tool, means that these measures
are now accessible quickly and
easily. The app was developed for
global application and it has been
tested in Rotterdam, Delft, Ho Chi
Minh City, Copenhagen and New
Orleans. The Climate App can be
used via
and it
is available in the Apple Appstore
and the Google Playstore.
Delft 3D 4.01
release for
Windows and
Linux
July saw the global release of Delft3D
4.01 for both Windows and Linux. This
latest, fully-validated Delft3D release
was designed specially to investigate
hydrodynamics, sediment transport,
and morphology and water quality in
river estuaries and coastal zones. This
version includes components such as
the Wind Enhance Scheme (WES) for
accurate storm-surge, hurricane and
typhoon simulations, and advanced
techniques for parallel calculations
with Delft3D-FLOW. Delft3D 4.01 is
available straightforwardly as a part of
a range of Delft3D Service Packages
such as the Delft3D Basic Service
Packages, Advanced Service Packages
and the Professional Service Package.

RESULTS OF THE STUDY LOOKING AT
‘SLURRY’ TRANSPORT EXPLAINED
Deltares has signed a Memorandum of Understanding with
Kuwait's ‘Environment Public Authority’ (EPA), the govern-
ment agency responsible for the country's environment.
Deltares will support EPA in a range of areas, including
knowledge for the sustainable management from urban
areas, coastal zones and wetlands (Photo: Raja Dawood
