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.
