AbstractThis section presents a comparison between three sources of inflows for the Caniapiscau and Churchill Falls basins in the Quebec-Labrador peninsula, namely observational data, ARCHIVES reconstructions and climatic simulations, whether regional from CRCM4 driven ERA40C (1960-2000) or global from CMIP3's GCM (1850-2100). Over the most recent period, 1960-2000, the regional simulation produced on a small domain (Quebec) reproduces rather well the characteristics of observations and reconstructions, while over a large domain (North America) it differs significantly from the observed distribution. For the period 1850-2000, the GCM simulations including all the forcings (natural and anthropogenic) generate water inputs whose certain important statistical properties are similar to the series of inputs reconstituted by dendrochronology.
Summary(Plain Language Summary, not published)
The main objective of the ARCHIVES project was to develop a new methodological approach aiming at reconstituting the long-term natural variability of hydro-climatic parameters used in the modeling of water inflows in basins of interest for hydroelectric production in Quebec. At the end of the project, hydropower resource managers and authorities concerned about climate change can benefit from a better understanding of the evolution in time and space of hydro-climatic conditions that will facilitate the development of appropriate hydrological scenarios for this region that is sensitive in many ways to climate change. This document presents a synthesis of the results produced by the multidisciplinary team of this five-year project, which took place over the entire boreal zone of Quebec and part of Labrador. This synthesis is structured in 21 chapters grouped in three distinct parts. The first part is divided into five chapters presenting fundamental concepts and prerequisites for reading the other sections of the document. The second part, which includes seven chapters, presents the treatment and meaning of the indicators used in the project. Finally, the nine chapters of the third part of the document present a retrospective analysis of the hydro-climate over the last centuries, or even millennia depending on the indicators.
