Unit Geo-engineering, Deltares Software Center (DSC)  

Deltares is an independent institute for applied research in the field of water, subsurface and infrastructure. Throughout the world, Deltares works on smart solutions, innovations and applications for people, environment and society. The main focus is on deltas, coastal regions and river basins. Managing these densely populated and vulnerable areas is complex, which is why Deltares works closely with governments, businesses, other research institutes and universities in The Netherlands and abroad. Its motto is Enabling Delta Life. As an applied research institute, the success of Deltares can be measured in the extent to which its expert knowledge can be used in and for society. For Deltares the quality of its expertise and advice is foremost. Knowledge is its core business.

All contracts and projects, whether financed privately or from strategic research budgets, contribute to the consolidation of Deltares' knowledge base. Furthermore, Deltares believes in openness and transparency, as is evident from the free availability of its software and models. Open source works, is Deltares' firm conviction. Deltares employs over 800 people and is based in The Netherlands in two cities, Delft and Utrecht.

Dr Hans Teunissen

Senior Research and Advisor

Dr Alexander Rohe

Senior Researcher and Advisor

Alexander Rohe was born on 4th June 1976 in Leonberg (Germany). He lived and studied in primary and secondary schools in south–west Germany. After attending the Technical Gymnasium in Leonberg (Germany) he fulfilled his civil service for one year at an old peoples home.
He started to study Civil Engineering at Stuttgart University in August 1996. In July 1999 he moved to Delft to continue his study of Civil Engineering at Delft University of Technology. He graduated in August 2004 at the chair of Soil Mechanics under supervision of professor Frans Molenkamp on the subject of ‘uniqueness of material models’ and obtained a M.Sc. degree in Civil Engineering.
In September 2004 he started as a research assistant at the Geo–engineering section of the Delft University of Technology under the supervision of professor Frans Molenkamp at the chair of Soil Mechanics. His research topic was the analysis and behaviour of material models towards parameter limits in numerical applications, and the research resulted in this doctoral thesis.
During the past years he wrote several papers for international conferences as well as international peer reviewed journals. He also acted as thesis advisor for graduation students and has fulfilled teaching activities for graduate students in the curriculum of the Master course of geomechanics. He participated in the international geomechanics network ALERT and attended the international network of MUSE for unsaturated soil mechanics. On national Dutch level he participated in the Graduate School of Engineering Mechanics.
Since May 2009 he is employed by Deltares, the Dutch Research Institute for Hydraulic and Geotechnical Engineering, located in Delft. There his research activities are related to soft soil engineering focussing on infrastructural projects and dike and offshore technology. Since July 2011 he is involved in the research programme concerning the Material Point Method (MPM) for numerical modelling of large deformations in soil–water interaction problems.

Joost Breedeveld, MSc

Senior Researcher and Advisor

After finishing his Bachelor of the Built Environment (including two traineeships in the field of foundation engineering at large Dutch contractors) in 1999, Joost Breedeveld obtained his Masters degree in Civil Engineering at Delft University of Technology. He graduated in January 2003 at the chair of Foundation Engineering under the supervision of prof Frits van Tol. Since February 2003 he works as geotechnical engineer for GeoDelft in Delft (The Netherlands), which in 2008 merged into Deltares (amongst others, with the former WL|Delft Hydraulics). This is an independent institute for applied research in the field of water, subsurface and infrastructure. His consultancy and research assignments include the (verification of the) geotechnical design of on shore, near-shore and off-shore structure (e.g. embankments, foundations, earth retaining structures and pipelines) in soft soil conditions. In recent years his focus has shifted to hydraulic structures, both within and out of the primary water defense structures in the Netherlands. While in many of these assignments the use of advanced models calculation models (including complex constitutive models) was essential, he has become an experienced user of calculation models based on the Finite Element Method (mainly PLAXIS).
Joost represents Deltares in several international networks (ELGIP, ECTP, ISSMGE) in the areas of delta technology and geo-engineering, of which some are aiming at influencing the EU programs that fund trans-national research cooperation (e.g. Horizon 2020, INTERREG, EurekaBuild). Through this work he got involved in the FP7 Marie Skłodowska-Curie action GEO-FLUID working on the extension of the material point method code for fluid-structure interaction and erosion. Within Deltares this was one of the (EU funded) predecessors of the current MPM-DREDGE project.

Dr Bruno Zuada Coelho

Researcher and Advisor

Bruno Zuada Coelho has obtained a 5 year degree in Civil Engineering from the University of Porto, in Portugal (specialisation in Geotechnics), followed by a Masters in Structural Engineering (2 years), where he developed a MSc thesis concerning the dynamic behaviour of piled slabs for high-speed railways.
In 2007 he started a PhD at Delft University of Technology, in the Netherlands, where he researched the dynamic behaviour of railway transition zones in soft soil.
Between 2011 and 2013, Bruno worked at TNO, the Dutch institute of applied sciences, as a Research Scientist in the Structural Dynamics group. During this period, he was member of the European project, CargoVibes. He was involved in the assessment of the performance of ladder track for the reduction of vibration propagation due to freight trains. Simultaneously, he coordinated the experimental evaluation of railway induced vibrations due to freight trains in Poland, Belgium and the Netherlands. At the same time, he developed numerical tools (Finite Element Method) for the analysis of soil-structure interaction problems.
Currently, he holds a research position at Deltares, where he is involved in the assessment of the performance of geotechnical infrastructures affected by gas extraction induced earthquakes. Additionally, Bruno is member of the Dutch workgroup for railway induced vibrations, and is involved in the development and application of numerical tools for geotechnical problems (Finite Element Method and Material Point Method).
His main areas of interest are soil dynamics and dynamic soil-structure interaction, and to applying this research to a variety of geotechnical problems, such as road and railway infrastructures, offshore foundations and pipelines.

Dr Mario Martinelli

Researcher and Adivsor

Mario Martinelli studied at “Sapienza” University of Rome (Italy). He got the degree (first level Italian degree) in Civil Engineering in 2006, the second level Italian degree in Geotecnical Engineering in 2008 and the PhD in Geotechnical Engineering in 2012.
During his PhD, he dealt with the study of advanced constitutive soil models of sands that he used in 3D FEM time-history coupled analyses. He spent 10 months at the University of California (Davis, USA) as a visiting PhD student working with particular attention on dynamic soil-structure-interaction and 3D FEM simulations with advanced constitutive models (soil and structure). From 2012 to 2013 he also worked as a post-doctoral researcher and teaching assistant at the University of Pavia (Italy), and 2 months again at UCDavis. Since January 2014 he is employed by Deltares, the Dutch Research Institute for Hydraulic and Geotechnical Engineering, located in Delft.
