Hatchery environmental assessments in Chile require sectoral permits for hydraulic works, channel modifications and river protection, with modelling the DGA and SEA can review.
We deliver the hydraulic component of PAS 155, 156 and 157: hydrology, modelling with and without the project, intake and outfall design, and drawings. Several files were prepared with PAS Consultora, including El Berro stream (Cuyamco) and Chonchi (St. Andrews); others for Salmones Austral (Caliboro) and Salmones de Chile (Pilmaiquén river).
HEC-RAS 1D/2D, HEC-HMS, QGIS, AutoCAD.
