| description | The type and intensity of forest management directly influences regional
catchment hydrology. Future forest management must optimise the effects of
its practices to achieve sustainable management. With scenario analysis of
forestry practices, the effects of different forest utilisation strategies on
the hydrology of forested catchments can be temporally and spatially
quantified.
<br><br>
The approach adopted in this study necessitated the development of an
interactive system for the spatially distributed modelling of hydrology in
relation to forest stand development. Consequently, a forest growth model was
used to simulate stand development assuming various forest management
activities. Selected simulated forest growth parameters were entered into the
hydrological model to simulate water fluxes under different conditions of
forest structure. The approach enables the spatially differentiated
quantification of changes in the water regime (e.g. increased
evapotranspiration).
<br><br>
The results of hydrological simulations in the study area, the Oker catchment
(northern Harz Mountains), show that forests contribute to the protection of
water systems because they have a balancing effect on the hydrological
regime. As scenario simulations also suggest, however, forestry practices can
also lead to substantial changes in water budgets of forested catchments. The
preservation of the hydrological services of forests requires a sustainable
and long-term forest conversion on the basis of current management directives
for near natural silviculture. Management strategies on basis of moderate
harvesting regimes are preferred because of their limited impact on the water
budget. |
