Project Detail
Flood Risk Assessment and Hydraulic Modeling – River L’Aire, Geneva
Location
Geneva, Switzerland
Project Type
Hydraulic Modeling and Flood Risk Assessment
Project Summary
This study presents a hydraulic analysis of the River L’Aire in Geneva, Switzerland, conducted using the HEC-RAS hydraulic modeling system. The analysis evaluated flood risks and riverbank stability along a 5.36 km river reach, considering flood scenarios with return periods of 10, 30, 100, and 300 years.
The study investigated hydraulic behavior under extreme discharge conditions and identified vulnerable river sections susceptible to flooding and erosion.
The results supported the evaluation of flood protection strategies including:
- Riverbank stabilization measures
- Flood diversion structures
- Retention basins and levee systems
- Reinforcement of existing riverbank protections
Technical Approach
The hydraulic modeling involved:
- Development of a HEC-RAS hydraulic model
- Simulation of multiple flood scenarios
- Flow velocity and floodplain mapping
- Evaluation of erosion-prone river sections
- Assessment of structural flood mitigation strategies
Engineering Contribution
