An existing statistical stream temperature model developed for British Columbia (BC), Canada, was refit to predict August mean stream temperatures, a common index of stream thermal regime also used in thermalscapes developed for the western United States (US). Thermalscapes of predicted August mean stream temperature were produced for 680,000 km of stream network at approximately 400 m intervals. Temperature predictions were averaged for 20-year periods from 1981-2100 to produce 86 scenarios: one for each historical period (i.e. 1981-2000, 2001-2020), and 21 for each future period (i.e. six global climate models and an ensemble average under three representative concentration pathways). The final model performance was consistent with other published regional-scale statistical models (R2 = 0.79, RMSE = 1.53 °C, MAE = 1.18 °C), performing well given the relative paucity of data, large geographic extent, and range of climatic and physiographic conditions. Model results suggested an average increase of August mean stream temperature of 2.9 ± 1.0 °C (RCP 4.5 ensemble mean ± SD) by end of century, with significant heterogeneity in predicted temperatures and warming rates across the province. Compared to stream temperature predictions from the western US, the predictions for BC showed good agreement at cross-border streams (Pearson’s r = 0.91), suggesting the possible integration of both products for a thermalscape covering much of western North America. These stream thermalscapes for BC address a major data deficiency in freshwater ecosystems and have potential applications to stream ecology, species distribution modelling, and evaluation of climate change impacts.RÉSUMÉLa température de l’eau est une caractéristique importante des écosystèmes d’eau douce, mais les ensembles de données complets sont largement insuffisants, ce qui limite la recherche et la gestion des espèces et des habitats d’eau douce. On a adapté un modèle statistique existant de la température des cours d’eau développé pour la Colombie-Britannique pour prédire les températures moyennes des cours d’eau en août, un indice commun du régime thermique des cours d’eau aussi utilisé dans les paysages thermiques élaborés pour l’ouest des États-Unis. On a produit les paysages thermiques de la température moyenne prévue au mois d’août pour 680000km de réseau de cours d’eau à des intervalles d’environ400mètres. On a calculé la moyenne des prévisions de température pour des périodes de 20ans de 1981 à 2100 en vue de produire 86scénarios: un pour chaque période passée (c.-à-d. de 1981 à 2000 et de 2001 à 2020) et 21 pour chaque période future [c.-à-d. six modèles climatiques globaux et une moyenne de l’ensemble de trois profils représentatifs d’évolution de la concentration (RCP)].

Here the possibility is explored for using simple methods to combine forecasts from a large-scale model, the Great Lakes portion of the National Surface and River Prediction System (NSRPS), and a regional system, the Système de Prévision Hydrologique (SPH) which covers southern Quebec, to improve regional forecasts. Outputs from the two forecasting systems are combined using multiple methods, including the simple mean, a weighted average in which the weights are optimized using the Kling-Gupta Efficiency (KGE), the Reduced Continuous Ranked Probability Score (RCRPS), and Ignorance Score (IGN) as cost functions, and weights calculated from the residual errors of the models. Bayesian Model Averaging (BMA) is also used to combine the probabilistic forecasts from both systems. The results show that it is possible to improve regional hydrological forecasts by using simple weighted combinations with forecasts from the large-scale system, even though the regional system performs clearly better. Performance is assessed via many well-known metrics, such as Nash-Sutcliffe Efficiency (NSE), KGE, RCRPS, and IGN. Results are averaged over 40 gauging stations and analyzed at lead times from 3 to 120 h. Improvements in all criteria for lead times over 60 h are observed, and there is no loss in performance at any lead times. Finally, the methods are used in a leave-one-out setup containing 29 validation basins to simulate performance on ungauged basins. The performance gain for ungauged basins is similar to that of the gauged basins, demonstrating that these simple methods can also improve forecasts in more remote territories where no gauging is available.RésuméLe développement et l’application étendue des modèles hydrologiques large-échelle ont produit des prévisions qui chevauchent régulièrement des prévisions hydrologiques régionales, plus spécifiques à un territoire.

However, over the past 20 years water levels have declined and the reasons are unresolved. Here we used a combination of inorganic geochemical analyses and stable water isotopes to constrain the hydrologic budgets of six lakes in the NSW. Our results show that the bedrock groundwater major element geochemistry is controlled by chemical weathering reactions along the flow paths and is dominated by lower δ18O and δ2H values (i.e. isotopically depleted), while the lake water generally shows unchanging evaporatively enriched stable isotope values and cation concentrations. An isotopic mass balance (IMB) technique combined with solution geochemical modelling using activity – activity plots reveals that deep groundwater input is negligible, while the lakes appear to lose a greater fraction of water inflows to evaporation (60%) than shallow groundwater and surface outflow (40%). The relative importance of shallow groundwater requires further study, as shallow groundwater sampling locations are scarce and surface outflow is negligible. The IMB technique also indicated that these prairie lakes have short water residence times, ranging from 1.8 to 10.4 yrs. Our results suggest that declining lake levels are likely the result of a changing relationship between precipitation and evaporation from the climatic norm.RÉSUMÉLes prairies et la plaine boréale du bassin versant de la rivière Saskatchewan Nord (RSN) du centre de l’Alberta abritent de nombreux étangs, marres et lacs peu profonds qui soutiennent des écosystèmes aquatiques uniques et constituent un habitat essentiel pour les oiseaux migrateurs en Amérique du Nord. Cependant, au cours des 20 dernières années, les niveaux d‘eau ont drastiquement diminué et les raisons environnementales restent inexpliquées. Cette étude utilise une combinaison d‘analyses géochimiques inorganiques et isotopiques de l‘eau pour contraindre les bilans hydrologiques de six lacs de la RSN. Nos résultats démontrent que les éléments majeurs des eaux souterraines sont contrôlés par des réactions liées à l’altération chimique sur les zones d’écoulements et sont dominés par des valeurs δ18O and δ2H plus basses (c‘est-à-dire isotopiquement appauvries). Au contraire, l‘eau des lacs montre généralement des valeurs isotopiques stables enrichies par l’évaporation et des concentrations constantes en cations. Une technique de bilan isotopique (IMB), combinée à la modélisation géochimique des solutions et des graphiques d‘activité révèle que l‘apport en eaux souterraines profondes est négligeable. En revanche, les lacs semblent perdre leur plus grande fraction des apports en eau par évaporation (60%), puis par les eaux souterraines peu profondes et les écoulements de surface (40%).

Utilizing an environmental history approach, and drawing from other fields such as historical geography, water policy, and political ecology, I show that Canada and the United States cooperatively manipulated border water environments on a large scale. Despite this coordination, there was often significant political and diplomatic controversy. I argue that coordinating or dealing with the United States deeply influenced the development of hydroelectricity in Canada, as well as the related hydraulic engineering expertise and technology. Moreover, transborder water politics also influenced many aspects of Canadian economic and political development, including federal-provincial relations. I explore themes such as Canada as a hydro state, the role of the Boundary Waters Treaty and the International Joint Commission, and concepts such as hydraulic nationalism and hydraulic imperialism.Keywords: Transboundary water politicsCanada-US relationswater diplomacyhydroelectricitywater quantity Disclosure statementNo potential conflict of interest was reported by the author.","PeriodicalId":55278,"journal":{"name":"Canadian Water Resources Journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135344212","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
