Assessment of the water resources of small rivers in the Republic of Moldova. Case study – Răut River

: About 90% of the total water resources in the country is represented by surface water resources. As a result of the reduction of the number of hydrological gauge stations, on the basis of which natural and disponible water resources can be assessed, it is proposed to assess them by identifying climate runoff. The obtained results allow the forecast of the changes of the water resources in the conditions of the environmental changes. Climate runoff is essentially determined as a difference between annual precipitation and evaporation, which depends on the geographical position and the orographic specificity of the studied territory. It is logical that they are subject of geographical zoning. In the paper are evaluated the climatic water resources based on whi ch the natural and disponible ones from the Răut river basin were calculated.
