“…Groundwater is the primary source of water supply for rural municipalities in the Canadian prairies, and sustains the baseflow of prairie streams that only occasionally receive inputs of overland flow. Numerical groundwater flow models coupled with hydrological land-surface models have been recognized as an effective tool for the sustainable development and management of groundwater resources in many parts of the world (Sophocleous and Perkins, 2000;Lubczynski and Gurwin, 2005, and references therein). Among the recent progresses in Canada is the coupling of a three-dimensional groundwater flow model MODFLOW (McDonald and Harbaugh, 1996) with a land-surface model called Hydrologic Evaluation of Landfill Performance (HELP) by Jyrkama et al (2002) and Scibek and Allen (2006).…”

Coupled hydrological modelling of land surface and groundwater is an effective tool for water resources management. The Versatile Soil Moisture Budget (VSMB) model is a simple landsurface model that has been widely used in the Canadian prairies to simulate soil moisture conditions of cropland. Its algorithm is suitable for coupling with a groundwater model, but VSMB has not been rigorously tested for grassland as such. The accuracy of simulated grassland evaporation was evaluated against three years of field data collected using the eddy-covariance technique near Calgary, Alberta. The current version of VSMB substantially underestimated evaporation. After modifications on growth stage parameters, radiation scheme, the drying curve function representing the ratio of actual to potential evaporation, and soil-column length, simulated evaporation was well within the error margin of observed values. In the semi-arid environment of the test site, simulated evaporation was relatively insensitive to soil water storage parameters but was sensitive to the drying curve function and soil-column length.Résumé : Les modèles hydrologiques couplés des eaux de surface et souterraine sont un outil efficace pour la gestion de ressources hydriques. Le 'bilan universel de l'eau du sol' (BUES) est un modèle pour l'eau de surface qui est couramment utilisé pour simuler les conditions de teneur en eau des sols de terres cultivables dans les prairies canadiennes. L'algorithme du BUES permet de le coupler avec des modèles d'eaux souterraines, mais il n'a pas encore été rigoureusement testé pour les prairies. La précision d'une simulation de l'évaporation pour une prairie a été comparée à des données de terrain acquises par la technique de covariance des tourbillons pendant trois ans sur un site près de Calgary, Alberta. La version courante du BUES sous-estime considérablement l'évaporation. Après des modifications aux paramètres des étapes de croissance, au schéma de radiation, et à la fonction de la courbe d'assèchement (qui représente le rapport d'évaporation actuelle et potentielle), l'évaporation simulée correspondait aux valeurs observées, à l'intérieur des marges d'erreur. Dans l'environnement semi-aride du site testé, l'évaporation simulée dépendait peu des paramètres de rétention d'eau des sols ; elle était plutôt liée à la fonction de la courbe d'assèchement. 188Canadian Water Resources Journal/Revue canadienne des ressources hydriques

“…This strategy is particularly important for evergreen trees that must survive a dry season. Several studies confirmed that Mediterranean oaks (Quercus suber and Quercus ilex in the Iberian Peninsula and Quercus douglasii in California) use this deep rooting strategy to tap water from groundwater reservoirs, whenever the superficial soil is dry and the water table is within the reach of the deep roots (David et al, 2004(David et al, , 2007(David et al, , 2013Lubczynski & Gurwin, 2005;Miller et al, 2010;Barbeta et al, 2015). This drought avoidance trait has also been observed in Australia (Zencich et al, 2002;O'Grady et al, 2006), South Africa (Le Maitre et al, 1999), China (Yin et al, 2015) and even in temperate forests during occasional droughts (Dolman, 1988).…”

Aim of the study: Water scarcity is the main limitation to forest growth and tree survival in the Mediterranean hot climate zone. This paper reviews literature on the relations between water and forests in the region, and their implications on forest and water resources management. The analysis is based on a hydraulic interpretation of tree functioning.Area of the study: The review covers research carried out in the Mediterranean hot climate zone, put into perspective of wider/ global research on the subject. The scales of analysis range from the tree to catchment levels.Material and methods: For literature review we used Scopus, Web of Science and Google Scholar as bibliographic databases. Data from two Quercus suber sites in Portugal were used for illustrative purposes.Main results: We identify knowledge gaps and discuss options to better adapt forest management to climate change under a tree water use/availability perspective. Forest management is also discussed within the wider context of catchment water balance: water is a constraint for biomass production, but also for other human activities such as urban supply, industry and irrigated agriculture.Research highlights: Given the scarce and variable (in space and in time) water availability in the region, further research is needed on: mapping the spatial heterogeneity of water availability to trees; adjustment of tree density to local conditions; silvicultural practices that do not damage soil properties or roots; irrigation of forest plantations in some specific areas; tree breeding. Also, a closer cooperation between forest and water managers is needed.

“…Pumping tests 5 are primarily influenced by local hydrogeological conditions and therefore, if the hydrogeology is highly variable, the results are not valid for a wider area and therefore of limited value in larger-scale groundwater studies (Lubczynski and Gurwin, 2005). Groundwater potential mapping 6 is a very powerful tool for estimating groundwater recharge in large vegetated areas.…”

“…However, this hydraulic conductivity is artificial and describes flow through a completely theoretical 'equivalent porous medium'. The success of this approach lies not in its theoretical beauty but in the fact that it has been applied successfully to model Pierer E.

Potable water consumption in Kuala Lumpur and the su1Tounding area is expected to grow by 34% from 2005 to 2010. This increase in demand will be met by the construction of new reservoirs. However, reservoirs are dependent on rainfall and during prolonged periods of drought, as occurred in 1998, they could become empty.Therefore it is of great importance to develop alternative sources of water supply, including groundwater, to mitigate the effects of a serious water crisis. In this paper, results fron1 a preliminary study on Kuala Lumpur's groundwater resources are presented. Modelling of the city's groundwater resources is extremely difficult given the limitations imposed by data availability and the karstic nature of some aquifers.Hence, the research presented here serves as a sta11ing point for further studies rather than providing any definitive conclusions. In addition to the study results, the planning implications of groundwater extraction are discussed.
