Abstract The paper discusses the
development of European policies and measures aimed at securing water demands
by replenishing, saving and protecting the European water resources. Recent
European policies and legislation give preference to soft solutions and
measures for water quality protection, rather than hard solutions, such as
construction of water storage reservoirs, which were formerly used for meeting
water demands. A case study from the Czech Republic describes results showing
possible reservoir storage capacities which could be necessary in future for
compensation of climate change impacts on flows, and particularly on low flows.
The required storage capacities are derived from drought deficit volumes
calculated from monthly flow series simulated for natural climate conditions
and for the conditions affected by climate change. For the derivation of the
deficit volumes, the discharge whose probability of exceedence is 70% (Q70%,)
was used as the threshold.
