✦ Synopsis
The hydrological sensitivities to long-term climate change of a watershed in Eastern Canada were analysed using a deterministic watershed runo model developed to simulate watershed acidi®cation. This model was modi®ed to study atmospheric change eects in the watershed. Water balance modelling techniques, modi®ed for assessing climate eects, were developed and tested for a watershed using atmospheric change scenarios from both state of the art general circulation models and a series of hypothetical scenarios. The model computed daily surface, inter-and groundwater ¯ows from the watershed. The moisture, in®ltration and recharge rate are also computed in the soil reservoirs. The thirty years of simulated data can be used to evaluate the eects of climatic change on soil moisture, recharge rate and surface and subsurface ¯ow systems. The interaction between surface and subsurface water is discussed in relation to climate change. These hydrological results raise the possibility of major environmental and socioeconomic diculties and have signi®cant implications for future water resource planning and management.
