CADAM3D is a user-friendly software based on the gravity method originally developed for one of the world biggest concrete dam owner, Hydro-Quebec, and for Dams and Hydrology of the Quebec Ministry of Environment (Quebec's legislator for dam safety). CADAM3D is fully functional and is intensively used by Hydro-Quebec since 2005. To our knowledge, no other software similar to CADAM3D is available at this time.

If you perform stability analyzes of concrete hydraulic structures, this software will allow you to perform them much faster and more efficiently.

CADAM2D (Computer Analysis of DAMs) is a software that has been primarily designed to support the learning of structural stability evaluation principles of concrete gravity dams. CADAM2D is also used to support research and development on the structural behavior and safety of concrete dams. CADAM2D is developed in a university context and has no commercial aspect. CADAM2D is based on the gravity method (rigid body equilibrium and beam theory). It performs stability analyzes for hydro-static loads and seismic loads.

CADAM2D has been offered free since 1997 for educational purposes only. However, we are aware that the product is heavily used commercially by many users. For this reason, we have removed from the software the possibility of generating new models as well as modifying the geometry. However, several models are available to allow users to familiarize themselves with the stability calculations of hydraulic concrete structures. If you would like to use a stability analysis software in your commercial activities, we offer CADAM3D.


RS-DAM is a computer program that was primarily designed to provide a computational tool to evaluate the transient response of a completely cracked concrete dam section subjected to seismic loads. RS-DAM is also used to support research and development on structural behavior and safety of concrete dams.

RS-DAM is based on rigid body dynamic equilibrium. It performs a transient rocking and/or sliding analysis of a cracked dam section subjected to either base accelerations or time varying forces. Several modelling options have been included to allow users to explore the influence of parameters (e.g. geometry, additional masses, variation of the uplift force upon rotation, hydrodynamic pressures in translation (Westergaard) and rotation, center of rotation moving with sliding, coefficient of restitution of impact, etc...). RS-DAM is developed in a university context and has no commercial aspect.


TADAM (Thermal Analysis of concrete DAMs) software employs a new frequency-domain solution technique to solve the 1D thermal transfer problem, allowing the calculation of temperature histories in a concrete dam section.

The direct solution calculates the evolution of the temperature distributions from the temperature histories of the upstream and downstream faces. The inverse solution uses temperature histories, measured inside the section, in order to calculate the temperature fields at the external faces, while taking into account the thermal wave attenuation effects and the phase angles along the section.

TADAM is developed in a university context and has no commercial aspect.
