The Sava River flows through SI, HR, BA and RS. The Sava River Basin represents an important part of the Danube River basin due to its natural heterogeneity and biodiversity. Although collection of data on environmental status is performed through the national monitoring programmes, most of the activities are limited to certain river sections, and particularly to chemical and biological parameters. No common database and data exchange mechanism has been established.So the main objective of this project is to propose a platform for efficient exchange of monitoring data and information in SRB. Expected Results: The outcomes of the project will provide supplementary information for the development of future water management plans and flood protection plans programmes dealing with different use of natural resources on local, national and transnational level (SRB Management Plan, Sediment Management Plan, Plans for the development of navigation, Protocols to the FASRB, Flood Risk Management Plan).
