Sažetak

According to theWater Framework Directive of the European Parliament
(2000/60/EC) (hereinafter referred to as the WFD), in addition to achieving the environmental
objectives of the river basin, the objectives are: achieving at least good water status of
water bodies, reducing the risk of water eutrophication, reducing sediment intake into
the waters, the conservation and integrity of NATURA 2000 sites, and the conservation of biodiversity and the functioning of ecosystem services. Environmental objectives can be achieved if adequate flow and sediment regimes for individual types of
watercourses and the associated watercourse morphology are guaranteed. Sediment
is associated with environmental quality standards or specific pollutants in the river
basin and therefore the WFD also applies to the management of sediment quality and
quantity. Sediment is an important, integral and dynamic part of a river basin because
the natural river needs sediment as a substrate for individual biological elements of
water quality and biological communities, and poses a risk of reaching various contaminants that can affect the biodiversity of riverbed communities and ecosystem
service opportunities. Sediment management is relevant to EU environmental legislation. On the example of the Sutla river basin, the intake of point and diffuse pollution
of the river basin by water and sediment into natural waters was analyzed, as well
as spatial information on its quantity and quality based on the SWAT mathematical
model and the results of surface water monitoring. Integrating sediment management
into integrated water management is a key element in improving monitoring. Mana-
ging the transboundary catchment of the Sutla River is a particular challenge, even
when Croatia and Slovenia are both EU Member States and are implementing the
WFD requirements.
