  1. Module 2: Water Budget, Pressures and Impacts, Significant Water Management Issues, Monitoring, Characterization ReportBasics on Water BalanceSenad Ploco

  2. Content Hydrology and hydrological cycle; River basin water budget; World water budget; WISE reporting on water balance.

  3. Introduction Where water comes from and where it goes? Why some of it is salty and some is fresh? Why sometimes there is not enough water and sometimes too much?

  4. Hydrology Hydrology = hydro + logos (water + science) A water science that deals with the occurrence, circulation and distribution of water ofthe earth and earth’s atmosphere. A good understanding of the hydrologic processes is important for the assessment of the water resources, their management and conservation on global and regional scales.

  5. Hydrologic (Water) cycle Evaporation from water bodies Water vapor moves upwards Cloud formation Condensation Precipitation/Snow Interception Transpiration Infiltration Runoff–streamflow Infiltration Deep percolation Ground water flow

  6. Evaporation and transpiration ET = Eg + Ei + Ed + Ew + Es + Et Eg - evaporation from snow and glacier surface Ei - evaporation of rainfall quantity intercepted by vegetal covering and also by constructions Ed - evaporation of rainfall quantity accumulated in ground depressions without possibilities of infiltration Ew - evaporation from water surface Es - evaporation from soil surface without vegetation Et - transpiration produced by the vegetation biological process

  7. Key river basin features Climate Shape Size Slope Soil type Hydrogeology Storage capacity

  8. Orographical vs topografical watershed

  9. River Basin Water Budget (km3) Vin – Vout = ΔV (km3)

  10. River Basin Water Balance (mm)

  11. World Water Budget Total quantity: 1386.0million km3 Saline water (oceans): 1337.5 million km3 Land water: 48.5 million km3 Land water 13.8 M km3 is again saline 34.7 M km3 is fresh water 10.6 M km3 is both liquid and fresh 24.1 M km3 is a frozen ice andglaciers in the polar regions and mountain tops

  12. Annual World Water Balanace

  13. Water balance of continents

  14. Water balance of continents

  15. Water balance of oceans

  16. Trends in the World

  17. Some EU rivers April 2005, Laktasi, B&H

  18. WISE and Water Balance Reporting by EU MS on: Water availability; Water abstraction; Water use.

  19. WISE - Water availiabilty Reporting per RBD on:

  20. WISE and Water Abstraction

  21. WISE and Water Use

  22. Water availability? Is there enough fresh water on the Earth? Current population number: 7.000.000.000 Specific water consumption: 80 l/d/cap
