  1. Part-financed by the European Union (European Regional Development Fund and European Neighbourhood and Partnership Instrument) MONITORING OF DAUGAVA RIVER – EXPERIENCES OF LATVIAN CASE STUDY RezekneHigherEducationInstitution, Latvia

  2. OVERVIEW • WATER RESOURCES IN LATVIA • DAUGAVAS RIVER BASIN (PROBLEMS AND SOLUTIONS) • INVESTIGATION OF WATER QUALITY IN LAKES AND RIVERS OF DAUGAVA RIVER BASIN • MONITORING OF DAUGAVA RIVER

  3. WATER RESOURCES IN LATVIA • EUROSTAT DATE: ESTONIA – 9 200, LITHUANIA – 7 300 MALTA – 100 m3

  4. WATER EXPLOITATION INDEX The water exploitation index represents the total volume of water abstracted in a given year as a share of total freshwater resources.

  5. RIVER BASINS IN LATVIA

  6. WATER BODIES IN LATVIA • Rivers 12,4 thousand Overall length 38 thousand km Density of rivers 600 m/km2 Daugava ( in Latvia 352 km, total 1005 km), Daugavas RB- 24,7 thousand km2. • Lakes 3000 Total space 1149 km2 or 1,7% of Latvia territory. In East Latvia - 40% of all Latvia lakes

  7. POLLUTERS • WASTE WATER (from 1998 volume of polluted waste water decrease about 70%) • POLLUTED TERRITORIES (125 places, from 2003 3 territories were rehabilitated) • AGRICULTURE • RUNOFF WOODLAND • 60% RUNOFF ARE OUTSIDE OF LATVIA • HYDROELECTRIC POWER STATIONS • EMERGANCE SITUACIONS

  8. MONITORING PLACES

  9. MAIN PLANNING DOCUMENTS • SUSTAINABLE DEVELOPMENT STRATEGY OF LATVIA UNTIL 2030 (LATVIA2030) • ENVIRONMENTAL POLICY 2009-2015 • ENVIRONMENTAL MONITORING PROGRAM2009-2012 • RURAL AREA DEVELOPMENT PROGRAM2007-2013 • RIVER BASIN MANAGAMENT PLANS

  10. Usuallylakesareused forfishfarming, tourism, recreation, other sectors of the economy development.

  11. OBJECT OF THE RESEARCH

  12. RUSONAS LAKE

  13. GERANIMOVA - ILZAS LAKE

  14. MATERIALS AND METHODS • CHEMICAL PROPERTIES DETERMINED BY SPECTROPHOTOMETRIC METHOD: • IRON ION QUANTITY, PHOSPHATE ION QUANTITY, SULFATE ION QUANTITY, AMMONIUM NITRATE ION QUANTITY • PH LEVEL; • CONDUCTIVITY; • CHEMICAL TESTS MADE: • TOTAL WATER HARDNESS, NITRITE AND NITRATE, TOTAL AND FREE CHLORINE • SOILANALYSIS • LICHENOINDICATION OF AIR QUALITY

  21. ZOOPLANKTON ANALYSIS

  22. Vides faktoru ietekme uz Daugavas vidusteces posma zooplanktonu (2008. – 2010. gads) Statistiski nozīmīgi (p>0,05) Pīrsona korelācijas koeficienti (r) starp zooplanktonu un abiotiskajiem faktoriem Vides faktoru ietekme uz zooplanktonu (RDA analīze) .

  23. CHANGES OF ZOOPLANKTO NEAR DAUGAVPILS CITY 1960-1970 AND 2008-2010

  24. AVERIGE AIR TEMPERATURE IN DAUGAVPILS, 1960-2010 (DATA FROM THE GLOBAL RUNOFF DATA CENTRE, KOBLENZ GERMANY, 2010)

  25. AVERAGE FLOW RATE IN DAUGAVA NEAR DAUGAVPILS, 1960-2010 (THE GLOBAL RUNOFF DATA CENTRE, 56068 KOBLENZ GERMANY, 2010)

  26. CHANGES OF ZOOPLNAKTON DEPEND OF FLOW RATE (1962., 2008. – 2010.)

  27. CHANGES OF ZOOPLNAKTON DEPEND OF SAPROBITATE (1962., 2008. – 2010.) 2008. g. S pieauga no 1,3 līdz 1,8. 2010. g. S pieauga no 1,3 līdz 2,2.
