12 Dynamics, Range, and Severity of Hydrological …

Presented results of analyses have finished some stage of the study. Knowledge of
hydrological droughts spatial pattern and time variability in Poland as well as their
determinants allows to use some conclusions in water management planning and
water resources assessment. It also might effectively support the tools and strategies
of optimal reduction of drought results, its prevention, and prediction.
When the defined scientific problems have been solved, new questions appeared.
It is possible to express it in one statement: does present level of knowledge allow to
construct the regional model of hydrological drought? This does not concern operational active model but the procedure predicting general level of drought streamflow
deficit expected in annual or half-yearly advance. In authors opinion, features of
investigated time series and identified regularities are so promising that the trial of
such study might be realized soon.
