Hydrogeological modeling for HPP Angostura. Bío Bío

— Project Description:

he Angostura hydroelectrical power plant has power installation of 316 MW, equipped with three Francis turbines. It is operating since 2014, after 48 months of construction.

— Description of Services:

Geological, geomechanical and hydrogeological studies in the extended area of the reservoir; numerical modeling of filtration in the set of the dam, and geomechanical characterization of the underground works: - Geological and geomorphological reliefs of the area of the reservoir, scale 1:10,000; - Geological – structural relief on site of the underground works and dam, scale 1: 2,000; - Log stratigraphic surveys, geological and geotechnical characterization of underground works; - Environmental impact study on the components of the soil and subsoil; - Hydrogeological study of the reservoir basin; - Slope stability study of the reservoir basin; - Risks analysis of the phenomena of landslide along the reservoir in operation; - Numerical modeling of the groundwater flow; - Calculation of the filtration flow rate through and under the embankment and the diaphragm; - Impact assessment on the aquifers and the rivers downstream of the reservoir.
