Abstract. Qualitative aspects of Crisul Repede River. The evolution of water quality over the Crişul Repede River is atypical because of natural and anthropic factors. The most significant factors are the geological substrate, and the settlements with their agricultural and industrial activity. The study was performed at three gauging stations for the period 1996-2006, taking into account the annual average values. The considered elements were: the discharge values, temperature, suspensions, oxygen regime, nutrients and phosphorus, taking into consideration their temporal and spatial variation. By comparing them with the admitted limits we could enroll them in various quality classes.

 

Keywords: Water quality, control section, spatial and temporal variation, admissible concentration, quality classes.
