Over the course of 25 we have conceived, processed and managed more than 150 projects. The following gallery should provide an overview over the spectrum of projects we have worked on. We have selected a few and categorized them.


Software development

We have developed two software-packages, that belong to the most efficient and complex 1D-simulation tools: Flux.DSS/DESIGNER and Flux.VIRTUAL RIVER. Both packages are explicitly as commercially available, off-the-shelf programs designed. Through systematic quality management and a careful, well planned strategy, we were able to develop these projects with a – compared to the competition – small team.

Besides, we have developed several individual system programs. They typically work with online data, which is recorded in real time, and serve the operational inflow and flood forecast, the controlling of HPPs or they serve as information systems to visualize potentially flood affected areas.

Because most of our software is operated operationally and handling sensitive data, we have chosen robust solutions and quality assurance through comprehensive, systematic tests.


Probably the most powerful 1D-simulation package in the world to model hydrodynamic modeling of streams of water. With broad options to develop and use hydrodynamic models of water systems. Modules for hydrodynamics, regulation, sediment transport and inverse modeling.


By our knowledge, Flux.Virtual RIVER is the only commercially available 1D-simulation-package for real time simulation and the inclusion of software-in-the-loop or hardware-in-the-loop.

Flux.VIRTUAL RIVER has become an established numeric engine for training simulators. Also as a system for developing HPP control units.

Flood forecast systems and operational systems

All our flood forecast systems and operational systems are individual software, which were designed and parameterized for a special task.

All flood forecast systems which were developed with our help or by us personally are a combination of meteorological forecasts, hydrological models and – at least for big rivers like Danube, Inn, Salzach, or Lech – a hydrodynamic models.

All systems were developed in teams, which involved scientists and software experts. The scientific process was often done by universities or other scientific facilities.

Besides the technical implementation, support in business management and structuring is a core competence of GR Consult. Thus, we have collaborated in an EU project concernig the flood forecast system for the River March and we have been part of a consortium to develop a forecast system for the Salzach. In that consortium we were handling the commercial management.

1D and 2D simulations for analyses and planning

We mainly use hydrodynamic models to analyze big river systems und complex issues. Our projects cover the entire spectrum of 1D and 2D model usage in hydrology and water resource management. Issues, that need 3D models demand cooperation with experienced partners, with whom we have been working for years.


2D model of the Austrian Danube

The 2D model of the Austrian model was developed over the course of 10 years by combining different smaller models. The model was used for flood calculations, analyses and plans as well as for the reconstruction of the flood in June 2013. While working on this reconstruction, the model was an important foundation for a movie, which visualized the backgrounds and processes of the flood in the Eferdinger Becken.

1D model of the Austrian Drau

From 2001 to 2005 SCIETEC was working on an assignment from Austria Hydro Power (AHP) to model all HPPs along the Austrian Drau. Beside the hydraulic aspects, the complex HPP controlling and the sediment transport were of particular interest.

Model for a training simulator in Birsfelden

Trainings are an important tool in all fields, where critical situations have to be mastered as they provide a valuable opportunity to learn and prepare for any possible scenario.

In the field of water resource management, training simulators can be seen as trailblazers, even though they provide the possibility to gain real experience while facing no risk at all.

The development of the training simulator created the possibility to train staff regularly and systematically to avoid catastrophes when critical situations arise.
