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

“…1) are expected to have small effects on the observations. Potential effects of evaporation (Linacre 1993), porewater exchange (Nuttle and Hemond 1988), and air injection (Stanley et al 2009a) are evaluated in the supplementary information, but are expected to cause ~1% or less difference in saturation state for all gases. There was a small increase in nighttime ΔNe compared to the model evaluations not readily explained by the evaluated processes; as measured ΔNe≈0%, there was likely another source of diffusive exchange (e.g.…”

Ecosystem metabolism in salt marsh tidal creeks and ponds : applying triple oxygen isotopes and other gas tracers to novel environments

Salt marshes are physically, chemically, and biologically dynamic environments found globally at temperate latitudes. Tidal creeks and marshtop ponds may expand at the expense of productive grasscovered marsh platform. It is therefore important to understand the present magnitude and drivers of production and respiration in these submerged environments in order to evaluate the future role of salt marshes as a carbon sink. This thesis describes new methods to apply the triple oxygen isotope tracer of photosynthetic production in a salt marsh. Additionally, noble gases are applied to constrain air-water exchange processes which affect metabolism tracers. These stable, natural abundance tracers complement traditional techniques for measuring metabolism. In particular, they highlight the potential importance of daytime oxygen sinks besides aerobic respiration, such as rising bubbles. In tidal creeks, increasing nutrients may increase both production and respiration, without any apparent change in the net metabolism. In ponds, daytime production and respiration are also tightly coupled, but there is high background respiration regardless of changes in daytime production. Both tidal creeks and ponds have higher respiration rates and lower production rates than the marsh platform, suggesting that expansion of these submerged environments could limit the ability of salt marshes to sequester carbon.

Establishing satisfactory calculation methods of lake evaporation has been crucial for research and management of water resources and ecosystems. A 30 year dataset from Dickie Lake, south-central Ontario, Canada added to the limited long-term studies on lake evaporation. Evaporation during ice-free season was calculated separately using seven evaporation methods, based on field meteorology, hydrology and lake water temperature data. Actual evaporation determined during a portion of a year was estimated using a lake energy budget model, and the estimation was used as reference evaporation for evaluation of the seven methods. The deviation of method-induced evaporation from the reference evaporation was compared among the seven methods, and a performance rank was proposed based on the root mean squared deviation and coefficient of efficiency. As for the whole ice-free season (roughly May to November), the water balance was the best method, followed by Makkink, DeBruin-Kejiman, Penman, Priestley-Taylor, Hamon, and Jensen-Haise methods. As for shorter duration (a week to a month), the DeBruin-Kejiman was the best method, followed by Penman, Priestley-Taylor, Makkink, Hamon, Jensen-Haise, and water balance method. Annual and seasonal changes of energy budget terms and the compensation function of lake heat storage in evaporation flux were also analyzed.
