“…Limitations of the paired-basin approach highlighted by Macdonald et al (2003a) and Monteith et al (2006a;b) support the contention that combined monitoring-modelling studies will produce the greatest advances in our understanding of hydrologic response to forest disturbance (Thomas and Megahan, 1998;Putz et al, 2003;Buttle et al, 2005a;Moore and Scott, 2005). Schnorbus and Alila (2004) extended Whitaker et al's (2002) use of the Distributed Hydrology Soil Vegetation Model (DHSVM) to simulate harvesting effects on peak discharge in Redfish Creek (southwestern BC).…”

“…Such disturbances directly impact the hydrologic cycle, as well as pose indirect consequences in terms of management responses such as salvage harvesting. Moore and Scott's (2005;2006) paired-basin study at the 33 km 2 Camp Creek Watershed in BC is particularly timely, since it dealt with the hydrologic consequences of salvage harvesting of 27% of a basin following MPB infestation. Significant increases in streamflows during snowmelt as well as an advance in peak flow timing relative to the control were detected.…”

“…To date, most work on flow regime and water quality response to forest disturbance in Canada and elsewhere has focused on small (one to ten km 2 ) spatial scales (Moore and Scott, 2005), producing a "mismatch" between the spatial scale of study and that at which management decisions are made (regional drainage basins > 100 km 2 ). This knowledge gap is becoming critical in BC, where widespread salvage harvesting following the MPB infestation will disturb, over a relatively short period, significant portions of regional scale basins.…”

Recent research in forest hydrology in Canada is reviewed, with a focus on studies of hydrological and hydrochemical processes in natural and disturbed forest landscapes during the 2003-2007 period. The value of hydrologic classification schemes for understanding these processes and guiding effective forest management practices is highlighted, as are the spatially and temporally extensive hydrologic datasets needed to test these classifications. Studies of hydrologic response to natural and anthropogenic forest disturbance are reviewed, and the strengths and limitations of paired-basin experiments for assessing forest disturbance effects on watershed processes are evaluated. Recent shifts in the context of forest hydrology research in Canada are presented, such as issues of climate warming, the mismatch between experimental and management scales, and the increasing need to address cumulative effects of both natural and anthropogenic forest disturbance.Résumé : Les recherches récentes en hydrologie des forêts sont examinées, l'accent étant mis sur l'étude des processus hydrologiques et hydrochimiques dans les paysages forestiers naturels et perturbés de 2003 à 2007. La valeur des plans de classification hydrologique pour la compréhension de ces processus et pour l'orientation des pratiques de gestion efficace des forêts est mise en relief, tout comme les ensembles de données extensives, spatiales et temporelles, nécessaires pour tester ces classifications. Les études de la réponse hydrologique aux perturbations naturelles et anthropiques de la forêt sont examinées. Sont également évaluées les forces et les limitations des expériences entourant les bassins jumelés pour l'analyse des effets de la perturbation des forêts sur les processus liés aux bassins hydrographiques. Sont aussi abordés les changements récents touchant les recherches en hydrologie des forêts au Canada, notamment le problème du changement climatique, le décalage entre l'échelle expérimentale et l'échelle de gestion, et le besoin croissant de s'attaquer aux effets cumulatifs de la perturbation des forêts, d'origine naturelle ou anthropique. 114Canadian Water Resources Journal/Revue canadienne des ressources hydriques

“…This forward shift likely relates to the effect of warming over the last few decades, which would cause an earlier onset of melt independently of PDO phase. It could also reflect the effects of ongoing forest harvesting in the Coquihalla River catchment, which can produce marked increases in April streamflow due to a shift to earlier snowmelt in clear cuts (Moore and Scott, 2005). The other interesting feature is the contrast in streamflow between the earlier and later warm phases for Lillooet River.…”

Abstract:The Pacific Decadal Oscillation (PDO) is a large-scale climate system feature that influences the surface climate and hydrology of western North America. In this paper, we review the literature describing the PDO and demonstrate its effects on temperature, precipitation, snowfall, glacier mass balance, and streamflow with a focus on western Canada, and particularly British Columbia. We review how the PDO index was developed and discuss other North Pacific climate patterns that resemble the PDO. The impacts of PDO on glacier mass balance and streamflow from retrospective studies are also reviewed and illustrated with specific examples from BC. We assess the current state of knowledge regarding the PDO and provide a critical assessment of its use in hydroclimatology. This information should provide insight on the sensitivity of projects to climatic variability.

“…Bowling et al (2000) noted this issue in a paired catchment study of larger catchments where about 25% of the precipitation events occurred only in one of the paired catchments. For larger snow-dominated catchments this limitation might be less severe (Troendle et al, 2001;Moore & Scott, 2005). Land-use or land-cover (LULC) changes are typically more gradual for larger catchments and often occur over only a portion of the total catchment area.…”

Land-cover impacts on streamflow: a change-detection modelling approach that incorporates parameter uncertainty. Hydrol. Sci. J. 55(3), 316-332. AbstractThe effect of land-use or land-cover change on stream runoff dynamics is not fully understood. In many parts of the world, forest management is the major land-cover change agent. While the paired catchment approach has been the primary methodology used to quantify such effects, it is only possible for small headwater catchments where there is uniformity in precipitation inputs and catchment characteristics between the treatment and control catchments. This paper presents a model-based change-detection approach that includes model and parameter uncertainty as an alternative to the traditional paired-catchment method for larger catchments. We use the HBV model and data from the HJ Andrews Experimental Forest in Oregon, USA, to develop and test the approach on two small (<1 km 2 ) headwater catchments (a 100% clear-cut and a control) and then apply the technique to the larger 62 km 2 Lookout catchment. Three different approaches are used to detect changes in stream peak flows using: (a) calibration for a period before (or after) change and simulation of runoff that would have been observed without land-cover changes (reconstruction of runoff series); (b) comparison of calibrated parameter values for periods before and after a land-cover change; and (c) comparison of runoff predicted with parameter sets calibrated for periods before and after a land-cover change. Our proof-of-concept change detection modelling showed that peak flows increased in the clear-cut headwater catchment, relative to the headwater control catchment, and several parameter values in the model changed after the clear-cutting. Some minor changes were also detected in the control, illustrating the problem of false detections. For the larger Lookout catchment, moderately increased peak flows were detected. Monte Carlo techniques used to quantify parameter uncertainty and compute confidence intervals in model results and parameter ranges showed rather wide distributions of model simulations. While this makes change detection more difficult, it also demonstrated the need to explicitly consider parameter uncertainty in the modelling approach to obtain reliable results.Key words change detection; forest hydrology; forest harvesting; HJ Andrews; HBV model Impacts de l'occupation du sol sur les écoulements en rivière: une approche de détection de changement par modélisation qui inclut les incertitudes sur les paramètres Résumé L'effet de la modification de l'occupation et de la couverture du sol sur la dynamique des écoulements reste mal compris.
