    ABSTRACT: Severe summer streamflow droughts are impacting many watersheds on Vancouver Island, British Columbia. Small coastal basins that are the primary water source for most communities and essential to Pacific salmon populations have been particularly affected. In the face of more extreme climate change-induced droughts, water managers often underestimate worst-case scenario low flows because the most extreme naturally occurring events are rarely captured within short instrumental records. To provide a long-term perspective on recent droughts on Vancouver Island, we developed a 477-year long dendrohydrological reconstruction of summer streamflow for Tsable River based on a network of annual tree-ring width data from climate-sensitive conifer trees. Explaining 63% of the instrumental streamflow variability, to our knowledge the record is the longest of its kind in British Columbia. We demonstrate that targeting the summer streamflow component derived from snowmelt is powerful for determining drought-season discharge in hybrid runoff regimes, and we suggest this approach may be applied to small watersheds in temperate environments that are not usually conducive to dendrohydrology. Our findings suggest that since 1520, 21 droughts occurred that were more extreme than recent “severe” events like those in 2003 and 2009. Recent droughts are therefore not anomalous relative to the ~400 year pre-instrumental record, and should be anticipated within water management strategies. In coming decades, worst-case scenario natural droughts compounded by land use change and climate change could result in droughts more sever than any since 1520. The influence of the Pacific Decadal Oscillation on instrumental and modeled Tsable River summer streamflow is likely linked to the enhanced role of snowmelt in determining summer discharge during cool phases.

    ABSTRACT: The frost table depth is a critical state variable for hydrological modelling in cold regions as frozen ground controls runoff generation, sub-surface water storage, and the permafrost regime. Calculation of the frost table depth is typically performed using a modified version of the Stefan equation, which is driven with the ground surface temperature. Ground surface temperatures have usually been estimated as linear functions of air temperature, referred to as “n-factors” in permafrost studies. However, these linear functions perform poorly early in the thaw season and vary widely with slope, aspect and vegetation cover, requiring site specific calibration. In order to improve estimation of the ground surface temperature and avoid site-specific calibration, an empirical Radiative-Conductive-Convective (RCC) approach is proposed which uses air temperature, net radiation, and antecedent frost table position as driving variables. The RCC algorithm was developed from forested and open sites on the eastern slope of the Coastal Mountains in southern Yukon, Canada, and tested at a high altitude site in the Canadian Rockies, and a peatland in the southern Northwest Territories. The RCC approach performed well in a variety of land types without any local calibration and particularly improved estimation of ground temperature compared to linear functions during the first month of the thaw season, with mean absolute errors <2 °C in seven of the nine sites tested. An example of the RCC approach coupled with a modified Stefan thaw equation suggests a capability to represent frozen ground conditions which can be incorporated into hydrological and permafrost models of cold regions.

    ABSTRACT: Groundwater ridging is the rapid rise of a shallow water table during a rainfall event, in an environment where, in the pre-event period, the capillary fringe extends to the ground surface. Groundwater ridging is widely cited to account for the observed significant appearance of pre-event water in a stream stormflow hydrograph. Various hypotheses have been advanced to explain the groundwater ridging mechanism; and most recently, from a field study site in South Africa, an energy hypothesis was proposed, which explains that groundwater ridging water table rise is as a result of rapid introduction and transmission of additional pressure head into the capillary fringe from an intense rainfall at the ground surface. However, there is need for further analysis and evidence from other field study sites to confirm and support this newly proposed energy hypothesis. The objectives of this paper are, therefore, to: review previous observations on groundwater ridging, from other study sites, in order to deduce evidence of the newly proposed energy hypothesis; present and evaluate a one-dimensional diffusion mathematical model that can simulate groundwater ridging water table rise, based on the newly proposed energy hypothesis; and evaluate the importance of a capillary fringe in streamflow generation. Analysis of previous observations from other study sites generally indicated that the rate of groundwater ridging water table rise is directly related to the rainfall intensity, hence, confirming and agreeing with the newly proposed energy hypothesis. Additionally, theoretical results by the mathematical model agreed fairly well with the field results observed under natural rainfall, confirming that the rapidly rainfall-induced energy is diffusively transmitted downwards through pore water, elevating the pressure head at every depth. The results in this study also support the concept of a three-end member stream stormflow hydrograph, and contribute to the explanation of how catchments can store water for long periods, but then release it rapidly during storm events.

    ABSTRACT: Groundwater catchment boundaries and their associated groundwater catchment areas are typically assumed to be fixed on a seasonal basis. We investigated whether this was true for a highly permeable carbonate aquifer in England, the Berkshire and Marlborough Downs Chalk aquifer, using both borehole hydrograph data and a physics-based distributed regional groundwater model. Borehole hydrograph data time series were used to construct a monthly interpolated water table surface, from which was then derived a monthly groundwater catchment boundary. Results from field data showed that the mean annual variation in groundwater catchment area was about 20% of mean groundwater catchment area, but interannual variation can be very large, with the largest estimated catchment size being approximately 80% greater than the smallest. The flow in the river was also dependent on the groundwater catchment area. Model results corroborated those based on field data. These findings have significant implications for issues such as definition of source protection zones, recharge estimates based on water balance calculations and integrated conceptual modelling of surface water and groundwater systems.

    ABSTRACT: This paper examines the impacts of climate change on future water yield with associated uncertainties in a mountainous catchment in Australia using a multi-model approach based on four global climate models (GCMs), 200 realisations (50 realisations from each GCM) of downscaled rainfalls, 2 hydrological models and 6 sets of model parameters. The ensemble projections by the GCMs showed that the mean annual rainfall is likely to reduce in the future decades by 2–5% in comparison with the current climate (1987–2012). The results of ensemble runoff projections indicated that the mean annual runoff would reduce in future decades by 35%. However, considerable uncertainty in the runoff estimates was found as the ensemble results project changes of the 5th (dry scenario) and 95th (wet scenario) percentiles by −73% to +27%, −73% to +12%, −77% to +21% and −80% to +24% in the decades of 2021–2030, 2031–2040, 2061–2070 and 2071–2080, respectively. Results of uncertainty estimation demonstrated that the choice of GCMs dominates overall uncertainty. Realisation uncertainty (arising from repetitive simulations for a given time step during downscaling of the GCM data to catchment scale) of the downscaled rainfall data was also found to be remarkably high. Uncertainty linked to the choice of hydrological models was found to be quite small in comparison with the GCM and realisation uncertainty. The hydrological model parameter uncertainty was found to be lowest among the sources of uncertainties considered in this study. Copyright © 2015 John Wiley & Sons, Ltd.
