Tackling reservoir silting requires analysis at several levels:
- Definition of the quantity and distribution of sediments through bathymetric and topographic surveys
- Assessment of the chemical-physical quality of sediments (sampling and chemical-physical, microbiological and ecotoxicological analyses)Definition of the removal interventions (flushing and mechanical removal) of the management methods of the sedimented materialIdentification of prevention and mitigation actions to avoid and/or reduce the impact of these activities on environmental components
- Definition of monitoring plans (biological, chemical-physical, morphological) for sediment removal activities
In marine areas where dredging interventions are planned, CESI can provide the following services:
- Assessment of sediment quality in accordance with current legislation, through the design of the characterization plan
- Application of the plan regarding the different types of surveys (remote operated vehicle seabed inspections, sediment sampling and assessment, side scan sonar surveys)
