Background

Artelia was commissioned to study the sedimentary and hydraulic impact of building Jirau hydroelectric dam on Rio Madeira.

Description

  • Modelling of a stretch of river measuring 30 km
  • Representation of various annual flood hydrographs
  • Measuring equipment including continuous level measurements, automatic injection of upstream flood hydrograph and a beam for performing topographic surveys of the reservoir

Aims of study

Model with development
Model with development

  • Calibration tests in natural conditions
  • Observation of reservoir sedimentation in with-project conditions,
  • Testing of various solutions for developing or managing the power plants with a view to maintaining downstream annual sediment transport
