About TT-Hydraulics


TT-Hydraulics was established in the spring 2013 by Thomas Ruby Bentzen and Torben Larsen in order to provide specialized consulting in hydrodynamics within the areas of hydraulic, coastal and environmental engineering. TT-Hydraulics is private limited company jointly owned by Thomas and Torben. Both have a long theoretical and practical experience within the subject area and maintain a comprehensive network of scientists and engineers nationally as well as internationally


Most often the service offered primarily includes a combination of system analysis and hydrodynamical computer modeling, where the work is presented in a report.

We are open for all types of collaboration as consultancy, knowledge sharing, quality control, professional discussions etc. Contact us for an informal talk about the opportunities.
