“…While no data are available to quantify the extent of this phenomenon in the St. Lawrence River watershed, the impacts of deforestation on streamflow in North American rivers are well-known. Numerous studies (e.g., [29][30][31]) have shown that deforestation induces an increase in extreme minimum streamflow and, to a lesser extent, in extreme maximum flows. Such changes are different from those observed in winter and spring minimum and maximum water levels in the St. Lawrence River, which decrease significantly over time.…”

Abstract:Although climate models predict that the impacts of climate change on the temporal variability of water levels in the St. Lawrence River will be seasonally-dependent, such a seasonal effect on the current variability of extreme water levels has never been analyzed. To address this, we analyzed the temporal variability of three hydrological variables (monthly daily maximums and minimums, as well as their ratio) of water levels in the St. Lawrence River measured at the Sorel station since 1912, as they relate to climate indices. As for stationarity, the shifts in the mean values of maximum and minimum water levels revealed by the Lombard method took place prior to 1970 for spring water levels, but after that year, for winter water levels. Changes in the winter stationarity are thought to mainly relate to the decreasing snowfall observed in the St. Lawrence River watershed after 1970. In contrast, for spring, these changes are likely primarily related to human activity (digging of the St. Lawrence Seaway and construction of dams). Two shifts in the mean values of fall minimum extreme water levels were highlighted. The first of these shifts, which occurred in the first half of the 1960s decade, can also be linked to human activity (digging of the St. Lawrence Seaway and construction of dams), whereas the second shift, observed after the 1970s for the months of November and December, can be linked to decreasing amounts of snow in winter. AMO (Atlantic Multidecadal Oscillation) is the climate index that is most frequently correlated negatively with the hydrologic variables, mainly in winter and spring.

Abstract. Hydrological and pollutant fate models have long been developed for research purposes. Today, they find an application in integrated watershed management, as decision support systems (DSS). GIBSI is such a DSS designed to assist stakeholders in watershed management. It includes a watershed database coupled to a GIS and accessible through a user-friendly interface, as well as modelling tools that simulate, on a daily time step, hydrological processes such as evapotranspiration, runoff, soil erosion, agricultural pollutant transport and surface water quality. Therefore, GIBSI can be used to assess a priori the effect of management scenarios (reservoirs, land use, waste water effluents, diffuse sources of pollution that is agricultural pollution) on surface hydrology and water quality. For illustration purposes, this paper presents several management-oriented applications using GIBSI on the 6680 km 2 Chaudière River watershed, located near Quebec City (Canada). They include impact assessments of: (i) municipal clean water program; (ii) agricultural nutrient management scenarios; (iii) past and future land use changes, as well as (iv) determination of achievable performance standards of pesticides management practices. Current and future developments of GIBSI are also presented as these will extend current uses of this tool and make it useable and applicable by stakeholders on other watersheds. Finally, the conclusion emphasizes some of the challenges that remain for a better use of DSS in integrated watershed management.

“…However, the impacts of such environmental changes vary between climate regions and between watersheds within the same climate region (e.g., [1][2][3][4][5][6][7]). In the current climate-warming context, in the province of Quebec (Canada) for instance, a decrease in minimum streamflow is expected to result from increased evapotranspiration and lower springtime precipitation (lower infiltration) due to climate warming [8,9]. Human activity could, however, prevent such a decrease.…”

“…Human activity could, however, prevent such a decrease. For instance, in a climate-warming context, according to [8], deforestation would lead to a significant increase in minimum flows in summer in the Famine River watershed, a tributary of the Chaudière River. Using several general circulation models coupled with a hydrological model, [9] analyzed the impact of increased agricultural surface area, associated with increased temperature, on the evolution of summer minimum flows, among other things, in the Chaudière River watershed.…”

This study presents a comparison of the spatio-temporal variability of characteristics (magnitude, duration and timing) of annual minimum daily extreme flows (AMEF) as a function of land use and the mode of management of dams. Streamflow measured at stations not affected by dams at Joliette, along the L'Assomption River (agricultural watershed, 1340 km 2 ), and at Saint-Michel-des-Saints, on the Matawin River (forested watershed, 1390 km 2 ) on one hand, and downstream from the Rawdon dam (regulated natural-type management mode), on the Ouareau River (1260 km 2 ), which is the main tributary of the L'Assomption River, and from the Matawin dam (inverted-type management mode), on the Matawin River (4070 km 2 ), on the other hand, were compared over the period from 1930 to 2010. As far as the spatial variability of natural rivers is concerned, the magnitude and duration of AMEF are higher in the forested watershed than in the agricultural watershed. In regulated rivers, AMEF magnitude is higher downstream from the dam characterized by a natural-type management mode than downstream from the dam characterized by inversion-type management. However, downstream from the latter, AMEF occur much more OPEN ACCESSWater 2015, 7 1233 frequently and very early in the year. As for temporal variability, the Lombard method did not reveal any influence of land use differences on the stationarity of series of AMEF characteristics. In contrast, differences in dam management mode result in occurrences of AMEF downstream from the inversion-type dam progressively earlier in the year. The duration and timing of AMEF are not correlated with the same climate variables, be it in natural rivers or downstream from dams.
