Completed campaign of measurement and characterization of sediments in the river Toltén

ERH Consult is planning a hydroelectric plant on the Toltén River (Araucanía – Chile). In order to characterize and quantify sediment transport in the catchment area of the plant, ERH Consult signed an agreement with the Polytechnic University of Catalonia (UPC) to carry out a measurement campaign to determine the degree of affection of this dynamics of materials to the works in project.

The campaign, organized by the Department of Hydraulic, Maritime and Environmental Engineering of the UPC, began in May, lasting until the end of September. Important human and technical resources were required, daily measurements were taken in the river during the whole campaign, capturing sediments with a Helley-Smith sampler (photo) and analyzing the samples in a laboratory implanted in Villarrica for this purpose.

The results of the campaign are expected to be completed in January 2014 and from which timely decisions will be made on the design of the proposed intake.
