An international team of 11 partners from eight countries was established to develop the SARIB project (http://www.sarib.net/). One part of this project is presented herein, including historical data, available GIS data from different sources and sediment quantity and quality data collected within the framework of the project. All data collected are available on http://www.ksh.fgg.uni-lj.si/sarib/. The Sava River is characterised by a torrential run-off and sediment regime upstream of the town of Sisak and by a lowland river regime downstream of it. The environmental status of sediments of the Sava River is generally comparable to the Danube River. According to targeted organic analyses, it may be concluded that the pollution of the Sava River sediments is low and generally lower than the pollution of the Danube River sediments.
