1. Regional workshop on SoE water quantity reporting of ETC/ICM with West Balkan countries Skopje, 10. – 11. January 2013. HRVATSKE VODE Marina Barbalić, M.Sc.Civ.Eng., marina.barbalic@voda.hrmarina.barbalic@voda.hr Mirjana Švonja, M.Sc.Civ.Eng., mirjana.svonja@voda.hrmirjana.svonja@voda.hr

2. Republic of Croatia - Area of the Republic of Croatia 56.538 km 2 - There are approximately 4 300 000 inhabitants - The relief is characterized by wide alluvial valleys, hilly/mountainous regions as well as karstic terrain

3. River Basin Districts (RBD) 1. the Danube River Basin District 2. the Adriatic Sea River Basin District Subbasins in Danube RBD 1.Sava river subbasin 2.Drava and Danube subbasin

4. The major Croatian rivers are – in the Danube River Basin District: the Danube, Sava, Drava, Kupa, Mura – the Adriatic Sea River Basin District: the Neretva, Lika, Zrmanja, Krka, Cetina

5. Institutions responsible for water quantity data collection and reporting: Croatian Meteorological and Hydrological Service (MHS) Hrvatske vode (legal entity for water management) Croatian Environment Agency (CEA) and Croatian Bureau of Stastistics

6. Meteorological observations are made by Croatian Meterological and Hydrological Service (MHS) in accordance with the regulations of the World Meteorological Organization (WMO) and national regulation. Observation are made at surface weather stations and upper-air observatories. Meteorological parameters are observed: - pressure - air temperature and humidity - sunshine - wind - snow pack - evaporation - precipitation etc. The meteorological data from several on-line stations can be found on the website http://meteo.hr, or can be obtained on request http://meteo.hr

7. Geographical distribution of weather stations in Croatia Mean annual precipitation in Croatia (data 1961-1990)

8. Hydrological monitoring in Croatia has long tradition. MHS together with Hrvatske vode and the Hrvatska elektroprivreda (Croatian Electricity Enterprise) has established a hydrological monitoring network. Today, the network consists of 561 hydrological stations (surface water). Monitoring of groundwater levels in Croatia is carried out systematically (with respect to the specific situation in karst region). Hydrlogical data that are observed: - water levels - discharge - sediment - water temperature - groundwater levels The measured data are available in the Hydrological Information System (HIS 2000), and can be obtained on request. Hrvatske vode has also established a system of on-line monitoring stations as a supporting tool for operational flood defence activities. The real-time monitored water levels from automatic hydrlogic stations can be found on the website http://voda.hrhttp://voda.hr

9. Hydrological monitoring network in Croatia Water balance of Croatia (data 1961-1990)

10. Water abstraction and Water use Collection of data: Hrvatske vode (for Water management purposes) Croatian Bureau of Stastistics (used for reporting)

11. Currently, in Croatia, all of the institutions mentioned are involved in diferent aspects of monitoring (data collection, data quality control, data systematization and reporting) of water quantity data. There is initiative to nominate Hrvatske vode as Nacional Topic Centre for Water, which should enable better and more systematic data flow, data collection, data control, data analysis and development of new products including those from questionnaire and other required by national, EU and other internacional obligations. Harmonization process is ongoing. Preparation of the document are in progress in Hrvatske vode: Long term program of monitoring (harmonization with EU requirements) Harmonization with EU Water Directives reporting requirements
