Personal profile

Personal profile

Robert Hack (Dr. H.R.G.K. Hack, CEng) is employed by University of Twente, Faculty of Geo-Information Science and Earth Observation (ITC), in Delft and Enschede in The Netherlands as Engineering Geologist since 1990. In this function he has been involved in teaching, research and consulting in the Netherlands and abroad. He has been president of the Dutch Association of Engineering Geologists (Ingeokring) and a member of various professional and scientific international committees. He is a member of the Institution of Mining and Metallurgy and a Chartered Engineer. 
Robert Hack worked as engineering geologist and geotechnical engineer in the Middle East, Far East, South America, and Africa. Several years he worked as senior rock mechanics engineer in the underground copper mines of Zambia and as geotechnical engineer in Indonesia. 
Robert Hack studied geology at the University of Leiden (BSc 1979) and engineering geology and exploration geophysics at the Technical University Delft and the University of Utrecht, The Netherlands (MSc 1983). He obtained his PhD (1996) from the Technical University Delft with the development of the Slope Stability Probability Classification (SSPC) system.



Robert Hack gives lectures in Soil and rock mechanics, site investigation, geophysics for engineering, slope stability, foundation engineering, tunnelling, and oil & gas and geothermal engineering. He supervises engineering geological fieldwork. He has supervised the research projects of some 100 Master of Science students from the Netherlands and abroad.

Research interests

Robert Hack is presently involved in research projects to the degradation of reservoir rock due to microbial action, determination and representation of uncertainty in engineering geological subsurface models, the development of methodologies for integrated data handling in large civil engineering projects, the three-dimensional effects of seismic waves on slopes, the degradation of soil and rock mass properties in time (rock and soil mass weathering), the determination of discontinuity data by laser scanning (Lidar), and in research towards the optimizing of the use of three-dimensional GIS and knowledge base systems for engineering geology. Robert Hack was a member of the programming and consortium committees of the Flood Control 2015 project that concerns developing a flood control system for the Netherlands, and is especially involved in the research to options to use remote sensing for determining dyke and dam stability. Within the research projects he has supervised various PhD students.


Activities in capacity development

Robert Hack has recently done projects as site investigations for the Beskyd Tunnel in the Ukraine, and slope stability, environmental impact, and road construction in Bhutan (Himalayas). He is involved in setting up an educational infrastructure for the geothermal, oil & gas, and renewable energy industry in Tanzania. He is regularly asked to participate in arbitrage in geotechnical engineering and to participate in advice committees on civil and geotechnical engineering. Recently he was a member of advice committees to the Ministers of Housing, Spatial Planning, and the Environment, Economic Affairs, and the Minister of Transport, Public Works, and Water management of the Netherlands, for the evaluation of the hazard and risks associated with CO2 storage in the deep underground (CCS), environmental sound exploitation of oil & gas, stability of salt mining caverns, underground radioactive waste respositories, exploitation of shale gas, and use of the Dutch subsurface in general. He is also a member of the Audit Committee for the subsidence due to gas exploitation under the Wadden Sea.
