The Rapel dam is located approximately 120 km southwest of the city of Santiago, Chile. Water is supplied from the reservoir to the Rapel hydroelectric plant built at the foot of the dam. It is a double curvature arch-type concrete dam with two large weirs at its ends to evacuate floods.
CESI has designed, supplied, installed and configurated automatic monitoring system for the dam to enable the check of the dam behavior in normal operation condition and after an earthquake can occur.
