Thomas, E. Baures Ecole des Hautes études en Santé publique Les impacts des changements climatiques sur la qualité des eaux n ont été que relativement peu étudiés par rapport aux aspects quantitatifs (ruissellement, inondation, sécheresse) et aux impacts sur l énergie (barrages). Si les facteurs affectants la qualité de l eau (température et régime hydrologique) sont bien connus, les effets sur les paramètres de qualité sont moins connus car très variables selon la nature des paramètres (matière organique ou nutrients, ), les situations (fortes pluies ou sécheresse), et le contexte hydrogéologique (substrat perméable ou non). L objet de cette présentation est de faire une synthèse des données de la littérature concernant les effets des changements climatiques sur l évolution des concentrations de matière organique (carbone organique dissous, COD), des nutrients (composés azotés et phosphorés), et de certains micropolluants (pesticides, pharmaceutiques, ). Pour chauqe famille de paramètre, les impacts de leur évolution sur l environnement et la santé seront étudiés. En particulier, l accroissement du COD des eaux destinées à la prodution d eau potable entrainera une difficulté de traitement et un accroissement des concentrations sous-produits de traitements tels que les THM (tri-halométhanes). Ces derniers induisent des risques sur la santé humaine, par ingestion ou inhalation. Pour les nutrients, les conséquences sur l accroissement de la biomasse aquatique et la fréquence d apparition des crises de cyanophycées sont importantes. Comme pour le COD, l accroissement des concentrations en micropolluants implique une modification des procédés de traitement. Les résultats présentés permettront de faire un état des connaissances et des manques dans le domaine et ainsi dégager des pistes de recherche et d actions prioritaires. 10 DRAIN-WARMF: A Watershed Scale Coupled Surface and Subsurface Flow/Water Quality Model S. Dayyani 1, S. Prasher 1, C. Madramootoo 2, A. Madani 3 1 PhD Candidate, Department of Bioresource Engineering, McGill University, Canada 2 Faculty of Agricultural and Environmental Sciences, McGill University, Canada 3 Department of Engineering, Nova Scotia Agricultural College Agricultural non-point source (NPS) pollution is one of the major threats to water quality in many countries of the world, including Canada. Although non-point source pollution originates at the field scale, usually water quality problems become more noticeable at the watershed scale. In Canada, several rivers, draining agricultural land, have elevated nitrate, phosphorous and pesticide concentrations. The Ministry of Agriculture of Quebec (MAPAQ) has stated that 85% of agricultural pollution is resulted from non-point sources. This research project is designed to improve our understanding of the processes contributing to NPS pollution from agricultural activities on a watershed scale in colder climates. An integrated approach is taken to model surface and subsurface flow and nitrogen transport by linking DRAINMOD 5.1 and WARMF models. In this modeling approach, surface flow/nitrogen is simulated using watershed-scale WARMF model, and subsurface flow/nitrogen is monitored using field-scale DRAINMOD model. The coupling results in a distributed parameter model based on the water balance of both models that calculates the total flow and nitrogen losses at the outlet of watershed. The linked model will be evaluated for the St. Esprit Watershed, located approximately 50 km northeast of Montreal. Once the model is validated, different alternatives and BMPs will be evaluated to reduce the risk of water contamination on the watershed. 11 Detection of trend and variability of precipitation in Southern Quebec and Ontario regions of Canada R. Doria, C.A. Madramootoo, A. Sarangi Brace Centre for Water Resources Management, McGill University, Canada Assessment of spatio-temporal variability of precipitation due to climate change has posed a serious challenge to the hydrologists, water resource engineers and managers. Efforts have been made by the researchers to use different data analysis methods and tools to accomplish these tasks. IPCC reports indicate completely contrasting results of precipitation change around the globe and as an example; the report portrays conclusive evidence of decreased precipitation over southern Africa region and increased precipitation over southern Quebec region. In this study, an attempt have been made to detect the trend and generate spatio-temporal variability maps using long term historical point rainfall data of 11 meteorological stations spanning over Southern Quebec and Ontario regions of Canada. First of all, the statistical downscaling techniques were employed to generate the long term local precipitation data from the General Circulation Models (GCMs ). The rainfall data for the period from 1961 to 2005 were used for calibration and validation of the regression based downscaling model. Further, both the observed and generated data up to the year 2050 were subjected to a non parametric statistical test viz. Mann-Kendall test to identify the trend in the daily, monthly and annual data under different seasonal and decadal settings. Subsequently, the generated precipitation amounts were subjected to geostatistical analysis using semivariogram models to generate the variability maps and estimate the precipitation amount at different locations within the study region. This will assist in quantification of the available water resources on field scales for agricultural water management activities leading to sustainable production. Over all, analysis of precipitation trends and its spatial extent on different temporal scales plays a significant role in studying the impacts of climate change on water resource availability and variability leading to judicious management and chalking out suitable adaptation measures pertaining to integrated water use for agricultural production. 12 Reducing Pollutant Discharge into Urban Rivers by Real-time Control of the Stormwater Retention Time in a Stormwater Pond J.F. Carpenter 1, M. Paré-Bourque 1, G. Pelletier 1, P. Van Rolleghem 2 1 Department of Civil Engineering, Université Laval, Québec, Canada 2 ModelEAU, Université Laval, Québec, Canada Preserving urban river ecosystems while providing access to riverbank parks is a goal shared by many Canadian municipalities for improving the quality of life of their citizens. It is easy to forget that they constitute a major part of the municipal drainage system. While vegetation on riverbanks plays an important role in decreasing velocities at which runoff reaches the river, the storm sewer network is the greatest accelerator, discharging stormwater more rapidly compared to natural runoff. This has a direct impact on river hydraulics through point discharges at relatively high velocities during rainstorms, which tend to disturb river ecosystems in the vicinity, as well as downstream, of the storm outlets. Stormwater also carries potential contaminants from runoff on the urban landscape that can negatively impact the local ecosystems. The objective of this contribution is to integrate real-time control (RTC) in stormwater management to reduce the impact on local aquatic ecosystems. This is achieved by managing stormwater from a typical urban catchment by equipping existing stormwater ponds with a dynamic sluice gate. The goal is to increase water retention time in the pond to increase sedimentation and thus removal of suspended solids and the pollutants attached to them. Based on modeling water quality and quantity and implementing dedicated control algorithms for the sluice gate, real-time control proved to be an effective solution for reducing the suspended solids discharge in the urban river. The challenge resides in adjusting the ponds sluice gates to retain stormwater as long as possible without causing overflow of the ponds and damages to neighbouring structures when the next rainfall comes in. In all studied cases, the controlled ponds offered a sedimentation efficiency higher than a traditional pond controlled solely by a static device, as in an orifice. Extending the retention time makes for increased sedimentation of fine particles, on which the majority of contaminants are agglomerated [1]. The modeling of suspended solids at the stormwater pond inlet and outlet helped demonstrate the efficiency of this solution by quantifying the pollutant load at these two points. The quantity of particles removed by sedimentation for the three studied summer periods was at least twice as large as in an uncontrolled pond. In the best of scenarios, the removal of particles reached 10 to 25 times that of a traditional pond. For the three summer periods, of 3000 kg of suspended solids entering the pond, only kg were released in
