ABSTRACT: This study describes the concept, instrumentation and application of groundwater/surface water interactions to the variable conditions within the Rideau valley watershed. In order to examine and evaluate the overall situation, ample data on water levels and seepage fluxes were collected during 1999 - 2001. The findings indicate the importance of climate change and other variables, such as hydraulic gradients and permeability that vary from one sub-watershed to the other. Within a certain year, the effects of the dry and wet periods are accentuated in some parts, whereas they are hardly felt in other parts. During the 1999, seepage fluxes had been minimal in many places. Where slope is not a major factor, the different permeability ranges across the overburden material have controlled the amount of seepage fluxes. The data also indicate that it is not only monthly but also the yearly climatic variations that affect the magnitude and direction of seepage fluxes.
RÉSUMÉ: Cette étude décrit le concept, l'instrumentation et l'application des interactions entre les eaux souterraines / de surface aux conditions variables dans le bassin versant de la vallée Rideau. Afin d'examiner et d'évaluer la situation globale, de nombreuses données sur les niveaux d'eau et les flux d'infiltration ont été recueillies au cours de 1999-2001. Les résultats indiquent l'importance du changement climatique et d'autres variables, telles que les gradients hydrauliques et la perméabilité qui varient d'une sous-ligne de partage à l'autre. Dans une certaine année, les effets des périodes sèches et humides sont accentués dans quelques endroits, tandis qu'ils sont à peine sentis dans d'autres. Pendant le 1999, l'infiltration jaillit avait été minimale dans beaucoup d'endroits. Là où la pente n'est pas un facteur important, les différentes gammes de perméabilité à travers le matériel de terrains de recouvrement ont commandé la quantité de flux d'infiltration. Les données indiquent également que c'est non seulement mensuel mais également les variations climatiques annuelles qui affectent l'importance et la direction des flux d'infiltration.
