WATER RESOURCE QUALITY MODELLING IN THE HYDROGRAPHIC BASIN OF THE BEGA RIVER

摘要

Water quality and water quantity (surface water and groundwater sources) are linked, even if these subjects have been treated too long as if they were independent. Water quality deserves attention because of its implications for affecting the public health, the economy and the quality of ecosystems. And even with large government investments in pollution control since in the last decades of the XX century, the nation waters continue to be damaged by pollution and misuse. Pollutants reach water bodies from point and nonpoint sources. Of special importance are the vestiges of toxic and hazardous materials disposal that are transported by surface and ground waters. Fot this purpose we have tried to use the water evaluation and planning (WEAP) model to simulate the surface water resource quality in the hydrographic basin of the Bega river, the chosen dead-line was the year 2015, also the dead-line to reach the environment objectives for the water bodies in Romania.
