– River length: 945 km (594 km ofwhich is the waterway)

– Discharge (mouth) 1700 m3/s (1st Danube tributary; contr. 25%)

• Framework Agreement on the Sava River Basin (FASRB, 2002)

– Countries involved: Bosnia and Herzegovina, Croatia, Serbia, Slovenia (as the FASRB Parties) and Montenegro (based on MoU)

• Key objective of FASRB:

Sustainable development of the regionthrough transboundary water cooperation

• Specific goals – to establish:

– International regime of navigation

– Sustainable water management

– Sustainable management of hazards

• International Sava River Basin Commission established in 2005 for implementation of FASRB (Secretariat: in 2006, seated in Croatia)

Background of cooperation


4

General principles of cooperation

• Exchange of data and information:

the Parties shall, on a regular basis, exchange information on the water regime of the Sava River Basin, the regime of

navigation, legislation, organizational structures, and administrative and technical practices

• Assessment of GIS capabilities of the countries (2007)

• Sava GIS Strategy (2008)

– Phase 1: Core Sava GIS functionalities

– Phase 2: Advanced tools, mapping and reporting services

– Phase 3: Advanced dynamic tools and services

• Implementing documents (2010)


• Flood Risk Management Plan (EU Floods Directive)

• Flood forecasting and warning system • Exchange of information• Flood defence emergency situations (incl. mutual assistance)

Protocol on Flood Protection to the FASRBSigned in June 2010, entered into force in November 2015

Protocol on Flood Protection to the FASRB - obligations

6

• In case of flood that induces or may induce transboundary impact, the Parties shall, without delay, inform the Parties that might be affected by this impact, through the system or any other appropriate manner in line with the agreed procedure for exchange of information important for flood defense

• The Parties shall, through the hydro-meteorological services and institutions responsible for flood protection, ensure timely exchange of meteorological and hydrological data, analyses and information important for flood protection, especially the timely forecast of high waters, in line with the agreed procedure

• The Parties shall establish a Flood Forecasting, Warning and Alarm System in the Sava River Basin and to jointly undertake all necessary actions for establishment of the System, including the development of the project documentation

• The Sava Commission shall coordinate the activities on establishment of the System

• After the System is established, the Parties shall ensure its regular maintenance and performance control, as well as regular training of the engaged personnel, with application of joint standards


Data Exchange Policy

• Principles (organizations, monitoring locations, data to be exchanged)

• Routes (procedures, timetable, quality standards, use and redistribution,

ownership, charging, future harmonization)

• Organizations (data providers/receivers)

– Hydro-meteorological services – Water / environment agencies– Hydropower companies (still pending)

• International legal framework– FASRB– Protocol on Flood Protection to FASRB– WMO Resolutions (25/Cg-XIII and 40/Cg-XII)– INSPIRE– Danube River Protection Convention– ISRBC’s Data Exchange Policy

• National legal framework


Sava GIS

– River basin management data

– Flood risk management data

– Other databases (in development)

• Navigation• Sediment management• Accident prevention and control

www.savagis.org

Database models are created based on

– WFD reporting Guidance 2016 v.4.9

– FD reporting Guidance 2017 v.2

– INSPIRE Directive and professional requirements

– WMO standards

– ICPDR database models (Danube GIS)

Common platform for sharing and dissemination of information and knowledge about WRM in the basin
