open file - Viru Peipsi

will start not in June but in May. It could cause a severe water
deficit in some small river basins in catchment area of River Pedja.
• Maximum runoff to be more sensitive than minimum runoff. Spring
floods have decreased, because of the lack of snow in the end of
winter period.
• All these modelled changes can be considered to be inside the
observed natural variation of rivers runoff during the baseline period
in 1961–1990.
• Changes of hydrological conditions should be translated into
changes in ecology of water-bodies also, because a number of
ecological processes dependent from hydrological conditions. It can
be concluded that positive impacts of climate warming on ecological
state of water-bodies are prevailing in study area.
• If minimum runoff will increase then it will act as a positive factor for
water management of rivers, especially for wastewater discharge,
navigation and recreational use.
