The research team consists of leading scientists in all disciplines relevant to this project
(data assimilation, ensemble forecasting, geodesy, hydrography, hydrodynamic modeling, and physical oceanography). External
advisors with specialist knowledge relevant for certain parts of the project are added to the team. This page presents the
research groups/ institutes involved in Versatile Hydrodynamics.
Geoscience and Remote Sensing
The project members of the
Geoscience and Remote Sensing (GRS)
department of the Faculty of
Civil Engineering and Geosciences of Delft University of Technology have a long record in realizing the height and depth
vertical reference surfaces being used in the Netherlands. They (i) developed the ‘De Min Geoide’ under contract of RWS (which
was the official Dutch geoid till 2004), (ii) developed methodology and software that have been used to compute the actual
Dutch geoid model NLGEO2004, and (iii) researched and developed the actual Dutch marine geoid model GEONZ97 (used by the RWS
and NLHS). Currently the team members are in charge to realize new quasi-geoid and LAT models for the Dutch mainland and continental
shelf. The GRS department is also responsible for the vertical stability of NAP using absolute gravity measurements under contract
of RWS, and for pre-processing and providing the Dutch data and meta-information needed to realize the EVRS. Starting in 2007, they
built in close cooperation with Deltares extensive knowledge in realizing instantaneous
water levels relative to a given quasi-geoid model using 2D hydrodynamic models. Based on this knowledge, several new applications
of such models in geodesy and hydrography are under development. The project members of GRS also have a record in sea level rise
studies and global isostatic adjustment modeling.

The project members at the
Mathematical Physics (MP)
group of the Faculty of Electrial Engineering,
Mathematics and Computer Science of Delft University of Technology have a long record in applying data assimilation in various
applications. For example the Kalman filter and calibration methods for the operational storm surge model in the Netherlands
were developed by the MP group (funded by RWS and Deltares). The projects are often carried out in close cooperation with the
institutes that create forecasts on a day to day basis, such as the air-quality forecasts by TNO and RIVM. Working in direct
cooperation with the end-users makes us aware of the challenges that real-life applications face, such as the need for good
computational performance, e.g., through parallel computing and the development of efficient algorithms (e.g., in the recently
finished Sangoma H2020 project). The MP group is one of the co-founders of the OpenDA association
and an active developer of the OpenDA open source software for data-assimilation.

The Physical Oceanography (PO)
group of the Faculty of Civil Engineering and Geosciences of Delft University of Technology has been active for many years
in the area of environmental flows, coastal oceanography (Rhine ROFI dynamics), transport of sediment, and development of
state-of-the-art coastal ocean models. Within this framework many research projects have been carried out, amongst others
ongoing studies on impacts of stratification on sediment dynamics on the Rhine ROFI research financed by STW (Sustainable
engineering of coastal systems in Regions of Freshwater Influence), and NWO ‘Flocs and fluff in the Delta: towards dynamic
particle properties in a SPM model for the Rhine-Scheldt ROFI’, and on climate change impacts funded by ALW (SCENES).
In addition, advanced model developments have been funded by TU Delft, the Alfred Wegener Institute, and by the Canadian
ArcticNet. A number of PhD theses have been completed on ROFI and estuarine dynamics and two are ongoing as part of an
international collaboration with National Oceanography Centre UK and University of Washington, and a third on flocculation
in the Rhine ROFI.

Aircraft Noise & Climate Effects
The section Aircraft Noise & Climate Effects (ANCE) of the Faculty of Aerospace Engineering of
Delft University of Technology
has long-term expertise in acoustic remote sensing research for both earth observation applications and applications in
the field of aircraft noise. For the Dutch Ministry of Infrastructure and the Environment, ANCE has developed the
publicly available software tool AMUST for predicting uncertainty in depth measurements. Within the Bodemblues project,
ANCE has developed a number of methods for acoustic classification of underwater sediments. These methods are currently
used by RWS for mapping sediments on the Cleaverbank, a Natura 2000 area.

Federal Agency for Cartography and Geodesy (BKG)
The Federal Agency for Cartography
and Geodesy (BKG) is the German service provider for topographic basic information, cartography, and geodetic
reference systems. The geodetic department of BKG is in charge of the definition and realization of the German geodetic
reference systems. Furthermore BKG provides the connections between German, European, and international reference frames.
In this scope BKG makes an important contribution to the international services for VLBI, GNSS, Laser ranging, gravity
field, and Earth rotation. BKG was one of the two computation centers both for the current German height reference frame
DHHN92 and for the new frame DHHN2016. Since 1994, BKG has been the data and computation center for the UELN. Within the
scope of its collaboration in EUREF (IAG sub-commission for European reference frames), BKG played a major role in the
definition of the EVRS and computed the previous realizations EVRF2000 and EVRF2007.
Deltares is a not-for-profit organization for
applied research and specialized advice. Most research is commissioned by governments in the Netherlands and abroad,
and by the private sector. A large part of these are end-users. Therefore, utilization of research can be considered
part of the core business of Deltares. Deltares has developed hydrodynamic models and operational forecasting systems
for many parts of the world. Deltares’ FEWS software environment forms the basis of dozens of operational forecasting
systems around the world. Deltares is also one of the leading developers and partners of the OpenDA open source association.
Furthermore, Deltares has a long experience in providing real-time data for tidal reduction of bathymetric data.
The open-source hydrodynamic modeling software of Deltares is used by thousands of end-users around the world.
This project will make use of Delft3D-FM, the successor of the famous Delft3D model.
