“…Clear-cutting significantly increased annual runoff (4-102 mm or 1-30 %) in C34 catchment only. The maximum annual treatment effect, 102 mm, its timing and duration was very similar to those reported in other Fennoscandian studies with the same proportion of clear-cut area (Ide et al 2013 and references therein). The lack of an increase in catchment C11 and C8 runoff was most probably due to the small proportion of the clear-cut area in these catchments (Bosch and Hewlett 1982;Stednick 1996;Ide et al 2013).…”

Catchments can also display different runoff responses depending on topography, soil properties, configuration and timing of harvesting, location of clearcut area in relation to the stream and the rate of regrowth (Hornbeck et al 1997;Kreutzweiser et al 2008;Abdelnour et al 2011).…”

“…The somewhat steeper slopes in C34 than the other two catchments could contribute to the increase in runoff after clear-cutting (Kreutzweiser et al 2008). Furthermore, in boreal catchments, where a considerable part of annual runoff takes place in spring, there are large interannual variations in snowmelt and streamflow responses after clear-cutting, with some years showing an increased runoff and others showing no effect (Ide et al 2013;Schelker et al 2013).…”

“…High runoff could induce more flow through the subsurface, organic-rich soil horizons and increase TOC export Schelker et al 2012). However, clear-cutting increases runoff mainly in spring (data not shown, Ide et al 2013) when the soil can be frozen and runoff is generated with little contact with organic soil horizons (Mattsson et al 2003;Köhler et al 2008).…”

“…Runoff and the excess load of substances can be expected to return to pre-harvest levels as the tree stands develop and water and nutrient uptake increases. That may take C20 years, since in similar climatic conditions seasonal runoff patterns have altered for 18 years (Ide et al 2013), and that most probably affects also the export of substances. There are only a few studies that report long-term effects of clear-cutting on runoff and stream water quality and their results differ from those of this study due to the various climatic and site factors, which affect the responses.…”

The long-term impacts of current forest management methods on surface water quality in Fennoscandia are largely unexplored. We studied the long-term effects of clear-cutting and site preparation on runoff and the export of total nitrogen (total N), total organic nitrogen (TON), ammonium (NH 4 -N), nitrate (NO 3 -N), total phosphorus (total P), phosphate (PO 4 -P), total organic carbon, and suspended solids (SS) in three paired-catchments in Eastern Finland. Clear-cutting and soil preparation were carried out on 34 % (C34), 11 % (C11), and 8 % (C8) of the area of the treated catchments and wide buffer zones were left along the streams. Clear-cutting and soil preparation increased annual runoff and total N, TON, NO 3 -N, PO 4 -P, and SS loads, except for SS, only in C34. Runoff increased by 16 % and the annual exports of total N, TON, NO 3 -N, and PO 4 -P by 18, 12, 270, and 12 %, respectively, during the 14-year period after clear-cutting. SS export increased by 291 % in C34, 134 % in C11, and 16 % in C8 during the 14, 6, and 11-year periods after clear-cutting. In the C11 catchment, NO 3 -N export decreased by 12 %. The results indicate that while current forest management practices can increase the export of N, P and SS from boreal catchments for many years ([10 years), the increases are only significant when the area of clear cutting exceeds 30 % of catchment area.

Abstract:Urban sprawl and regional climate variability are major stresses on surface water resources in many places. The Lake Simcoe watershed (LSW) Ontario, Canada, is no exception. The LSW is predominantly agricultural but is experiencing rapid population growth because of its proximity to the Greater Toronto area. This has led to extensive land use changes that have impacted its water resources and altered run-off patterns in some rivers draining to the lake. Here, we use a paired-catchment approach, hydrological change detection modelling and remote sensing analysis of satellite images to evaluate the impacts of land use change on the hydrology of the LSW (1994LSW ( to 2008. Results show that urbanization increased up to 16% in Lovers Creek, the most urban-impacted catchment. Annual run-off from Lovers Creek increased from 239 to 442 mm/year in contrast to the reference catchment (Black River at Washago) where run-off was relatively stable with an annual mean of 474 mm/year. Increased annual run-off from Lovers Creek was not accompanied by an increase in annual precipitation. Discriminant function analysis suggests that early (1992-1997; pre-major development) and late (2004)(2005)(2006)(2007)(2008)(2009); fully urbanized) periods for Lovers Creek separated mainly based on model parameter sets related to run-off flashiness and evapotranspiration. As a result, parameterization in either period cannot be used interchangeably to produce credible run-off simulations in Lovers Creek because of greater scatter between the parameters in canonical space. Separation of early and late-period parameter sets for the reference catchment was based on climate and snowmelt-related processes. This suggests that regional climatic variability could be influencing hydrologic change in the reference catchment, whereas urbanization amplified the regional natural hydrologic changes in urbanizing catchments of the LSW.

The assumption of uniform specific discharge: unsafe at any time?

Nearby catchments in the same landscape are often assumed to have similar specific discharge (runoff per unit catchment area). Five years of streamflow from 14 nested catchments in a 68 km 2 landscape was used to test this assumption, with the hypothesis that the spatial variability in specific discharge is smaller than the uncertainties in the measurement. The median spatial variability of specific discharge, defined as subcatchment deviation from the catchment outlet, was 33% at the daily scale. This declined to 24% at a monthly scale and 19% at an annual scale. These specific discharge differences are on the same order of magnitude as predicted for major land-use conversions or a century of climate change. Spatial variability remained when considering uncertainties in specific discharge, and systematic seasonal patterns in specific discharge variation further provide confidence that these differences are more than just errors in the analysis of catchment area, rainfall variability or gauging. Assuming similar specific discharge in nearby catchments can thus lead to spurious conclusions about the effects of disturbance on hydrological and biogeochemical processes.
