Hydroclimatic changes and drivers in the Sava River Catchment and comparison with Swedish catchments.

Levi L, Jaramillo F, Andričević R, Destouni G - Ambio (2015)

Bottom Line: In a hydropower dominated part of the SRC, unlike in an unregulated part, we find increase in average annual evapotranspiration and decrease in temporal runoff variability, which are not readily explainable by observed concurrent climate change in temperature and precipitation and may be more related to landscape-internal change drivers.Among the latter investigated here, results indicate hydropower developments as most closely related to the found hydroclimatic shifts, consistent with previous such indications in studies of Swedish hydropower catchments.Overall, the present results have quantitatively framed the recent history and present state of hydroclimate in the SRC, of relevance for water resources in several countries and for a majority of their populations.

ABSTRACT
In this study, we investigate long-term hydroclimatic changes and their possible relation to regional changes in climate, land-use and water-use over the twentieth century in the transboundary Sava River Catchment (SRC) in South Eastern Europe. In a hydropower dominated part of the SRC, unlike in an unregulated part, we find increase in average annual evapotranspiration and decrease in temporal runoff variability, which are not readily explainable by observed concurrent climate change in temperature and precipitation and may be more related to landscape-internal change drivers. Among the latter investigated here, results indicate hydropower developments as most closely related to the found hydroclimatic shifts, consistent with previous such indications in studies of Swedish hydropower catchments. Overall, the present results have quantitatively framed the recent history and present state of hydroclimate in the SRC, of relevance for water resources in several countries and for a majority of their populations. This provides a useful basis for further assessment of possible future hydroclimatic changes, under different scenarios of climate change and land/water-use developments in the region.

Mentions: In this study, we investigate the hydroclimatic change manifestations and their possible drivers in the major transboundary Sava River Catchment (SRC; Fig. 1), draining into the Danube River in South-Eastern Europe. The SRC represents a world region with relatively limited open accessibility to environmental data, spanning across countries that have undergone recent political and social instability, which also influences the data accessibility situation. For this region, we here use a wide range of sources to compile times series of hydroclimatic data, as well as data on land-use and water-use developments in the catchment over a large part of the twentieth century.Fig. 1
