Our Realizations
Harbor and beach "Port-Plage des Eaux-Vives" in Geneva
We realize for the EDMS office and the canton of Geneva all hydraulic analyzes, currentology, and support for infrastructure design.
Project amount: 100 million CHF
- Design of the port infrastructures
- Determination of particle size ranges
- Height, frequency, speed and direction of the incident waves
- Estimation of the wave-spray
- Energy and speed of the lake currents
- Probability and localization of erosion and sedimentation zones
- Temporal evolution of a tracer concentration
- Analysis of beach contamination
- Design of hydraulic structures
Sedimentation in Rossinière dam
We designed an economic solution of a canal built in the lake to remove further sedimentation.
Project amount: CHF 5 million
- Design of the port infrastructures
- Determination of particle size ranges
- Height, frequency, speed and direction of the incident waves
- Estimation of the wave-spray
- Energy and speed of the lake currents
- Probability and localization of erosion and sedimentation zones
- Temporal evolution of a tracer concentration
- Analysis of beach contamination
- Design of hydraulic structures
Artificial flood for the alluvial dynamic of the river "Petite Sarine"
We support the operator and the canton of Fribourg in the planning, implementation and monitoring of artificial floods. The goal is to promote natural floodplain dynamics.
Project amount: 0.3 Mio CHF
- Determination of flow rates required for the artificial flood
- Simulation of long term alluvial dynamics in the watershed
- Coupling hydrological and sediment simulation with RS sed
- Determination of the impacts of floods on the river morphology
- Monitoring of the artificial flood: time-lapse pictures, online measurement of bedload, measurement of hydraulic parameters (water level, turbidity, temperature, active RFID)
River restauration in Servion
We designed and realized the river restauration of the formerly channelled river. Located in the middle of an industrial area, the river has regained space and its ecological functions.
Project amount: 0.4 Mio CHF
- Determination of water levels and speeds with 1D simulation
- Design of civil engineering works: riprap, sills, dikes, river bed
- Realization of draft plans and execution
- Assistance to the client
- Construction management, quantity surveying
- Realization of a maintenance notice
Other engineering services
We carry out studies and modelling in many other areas related to water, energy, security and environment.
- Flood hazard maps
- Design and construction of small hydro
- Determination of design flood
- Determination of the hydrological regime of rivers
- Analysis of residual flows
- Analysis and numerical modelling of sediment transport
- 3D modelling for water projects
- Modelling lakes (waves, currents, sediment)
- Impacts of climate change on water flow and hydroelectric power generation
