Construction and first filling of Pinhão concrete face rockfill dam

Abstract

The Pinhão dam is located in the municipality of Vila Pouca de Aguiar in the district of Vila Real, intersecting the Pinhão River. Its primary purpose is to create an urban water supply reservoir of 4.24 x106 m3. The dam has a profile of granite riprap with a concrete face as the impervious curtain. The maximum height of the dam is 22 m. Construction took place between September 2006 and March 2008 when, after authorisation was given by INAG, first filling started. This paper is intended to provide basic data on the dam and its construction phase and on the monitoring activities undertaken by the ATMAD in close collaboration with LNEC and INAG to ensure the safe control of this dam.
