RezekneHigherEducationInstitution, Latvia


Overview

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


Water resources in latvia

WATER RESOURCES IN LATVIA

  • EUROSTAT DATE:

ESTONIA – 9 200, LITHUANIA – 7 300

MALTA – 100 m3


Water exploitation index

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.


River basins in latvia

RIVER BASINS IN LATVIA


Water bodies in latvia

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


Polluters

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
