The paper covers research on physiographic features and anthropogenic
factors influence on natural pond water storage. The problem was investigated
both at the level of the Dopływ spod Nowej Wsi catchment (27.53 km2) and the
smaller spatial unit Bagna Ramuckie natural pond (12.4 ha). Dynamics of physiographic
features, changes of hydrographical network and anthropogenic factors including
water, land and forest management practices were investigated.
The decisive factor modulating processes of water storage rebuilding for
investigated spatial units seems to be dynamics and long-term directional changes
of air temperature. Rebuilding of pond water storage occurred after a 40-year period
of air temperature decrease and the decline of water storage after a 20-year
period of air temperature increase. Precipitation had minor significance in modulating
pond water storage in long-term periods, because lack of long-term precipitation
trends in analysed period. Although in short-term periods precipitation have
important modulating impact on a decline of pond storage. The decline occurred
after the dry period from 1989 to 1995 as a result of high deficit of climatic water
balance. Spectacular rebuilding of pond water storage occurred in Bagna Ramuckie
after the cold and wet period from 1956 to 1965. Non-climatic physiographic
features and anthropogenic factors did not influence the processes of pond
water storage rebuilding and decline because both of these factors seemed to be
stationary over at least eight decades of 20th century, while processes of storage
rebuilding or decline lasted over the investigated spatial unit.
