Civil engineering structures

Hydraulic structures are essential to our every day lives:

The conception of these constructions, the choice of their layout, the definition of their interaction with water are all points that must be carefully considered to optimize the performance of the structure and limit its impact on the natural environment.

Our water development project service is conceived in order to allow contracting authorities and contractors to have access to an efficient technical and institutional assistance, in line with their needs and encouraging a global perspective.

Our contribution consists in analyzing, verifying and improving the conception of constructions, in particular the hydraulic component, by carrying out studies using reduced or numerical models.

We provide our services in different areas:

Water resource management is necessary when the demand exceeds the supply, which is more and more frequent given the continued search for optimal agricultural production.


A well-modelled catchment and a basic collection of data are sufficient to allow the estimation of available flow for direct use or for planning solutions to avoid water scarcity and look ahead the risks.

Artificial or natural reservoirs are carefully managed since the fish and nautical activity they foster can stimulate a region and bring about aquatic ecosystems rich in sensitive flora and fauna. [ Polynésie, 2002 ]


Although the Noria is a very old system, calculations or simple adjustments can be made in order to optimize the efficiency and reliability of its functioning. [ Egypte, 2003 ]

In addition to its main purpose, a retention tank can serve as a buffer during high flows following a storm. This reserve can be used for fire fighting or be consumed by the local population. [ Sri Lanka, 1994 ]


Time can wear down installations: the efficiency of a structure decreases and the risk of break down increases. A careful rehabilitation, whether total or partial, yields a well-controlled environment.
