“…For example, in arctic and subarctic systems, ice layers at the interface of the organic and mineral soils have often been cited as the main cause of lateral runoff (Kane et al, 1981;Roulet and Woo, 1988;McNamara et al, 1997), with much research emphasizing their role in water storage and restriction of transmittance properties (Santeford, 1979;Slaughter and Kane, 1979;Hinzman et al, 1993;McNamara et al, 1998). Seasonal fluctuations in the active layer for northern systems has been observed to directly influence the hydrologic response at the hillslope and catchment scales (Carey and Woo, 2001;Yamazaki et al, 2006;Woo et al, 2008). In addition, a long-term change in permafrost influences the hydrologic response.…”

Abstract:Catchment-scale transit times for water are increasingly being recognized as an important control on geochemical processes. In this study, snowmelt water mean transit times (MTTs) were estimated for the 15 Krycklan research catchments in northern boreal Sweden. The snowmelt water MTTs were assumed to be representative of the catchment-scale hydrologic response during the spring thaw period and, as such, may be considered to be a component of the catchment's overall MTT. These snowmelt water MTTs were empirically related to catchment characteristics and landscape structure represented by using different indices of soil cover, topography and catchment similarity. Mire wetlands were shown to be significantly correlated to snowmelt MTTs for the studied catchments. In these wetlands, shallow ice layers form that have been shown to serve as impervious boundaries to vertical infiltration during snowmelt periods and, thus, alter the flow pathways of water in the landscape. Using a simple thought experiment, we could estimate the potential effect of thawing of ice layers on snowmelt hydrologic response using the empirical relationship between landscape structure (represented using a catchment-scale Pe number) and hydrologic response. The result of this thought experiment was that there could be a potential increase of 20-45% in catchment snowmelt water MTTs for the Krycklan experimental catchments. It is therefore possible that climatic changes present competing influences on the hydrologic response of northern boreal catchments that need to be considered. For example, MTTs may tend to decrease during some times of the year due to an acceleration in the hydrologic cycle, while they tend to increase MTTs during other times of the year due to shifts in hydrologic flow pathways. The balance between the competing influences on a catchment's MTT has consequences on climatic feedbacks as it could influence hydrological and biogeochemical cycles at the catchment scale for northern latitude boreal catchments.

“…During the past few decades, a number of hydrological investigations in forest catchments focused on evaluating the effects of forest management on peak flow (e.g., Rothacher, 1973;Hudson, 2002;Guillemette et al, 2005) and recession characteristics (Hewlett and Helvey, 1970;Rothacher, 1973;Tallaksen, 1995;Carey and Woo, 2001). However, findings from these studies varied due to uncontrollable factors such as topography, size of storm events, soil characteristics, forest types, and harvesting methods.…”

“…Other aspects of the effects of forest management on storm runoff responses have been evaluated by hydrograph analyses, including response time with respect to precipitation, rising limb patterns, and recession limb characteristics (Griffiths and Clausen, 1997;Carey and Woo, 2001). Response time with respect to precipitation reflects the wetness of soil and topography of the catchments (Dingman, 1994).…”

“…Response time with respect to precipitation reflects the wetness of soil and topography of the catchments (Dingman, 1994). Patterns of the rising limb of hydrographs, including time to the peak, correspond to the intensity and duration of precipitation (Carey and Woo, 2001). Recession flow patterns, including the slope of recession hydrographs, reveal behavior of water storage which affects stream flow and low flow characteristics (Hall, 1968;Tallaksen, 1995;Sugiyama, 1996;Griffiths and Clausen, 1997).…”

Among these hydrograph parameters, recession analysis tended to be used more often for evaluating forest harvesting effects on soilwater availability (Hewlett and Helvey, 1970;Carey and Woo, 2001) in addition to peak flow characteristics (Hewlett and Helvey, 1970;Ziegler et al, 2001).…”

Snowmelt runoff has major influence on water supply and hazards for many temperate and polar regions. The magnitude and timing of runoff depend on the processes of snow accumulation and melt, which are controlled by factors that include latitude, topography, and land use. The amount of runoff production is affected by meltwater loss to evaporation and infiltration, the latter is often limited by frozen soil conditions. Runoff is delivered as flow in the snow, overland flow on bare ground, channeled flow in rills and interhummock cracks, or as subsurface flow in organic soils. The flow may be modified by the presence of snow or river ice in the channels, which often causes runoff delay and amplification of peak flows. Streamflow hydrographs for small basins typically show diurnal cycles with high discharge during warm days and declines in the cool and terminating periods of snowmelt. Hydrographs of large basins are an integration of the runoff patterns of their subbasins. In terms of snow management, the control of snowmelt floods is a consideration, yet many arid regions look to snowmelt runoff as a source of water supply.
