Numerical Solutions of TwoDimensional Mass Transport Equation in Flowing Surface Waters
Volume: 404
Series: E8
The problem of water quality receives an increasing attention of the public, politicians, decision makers nowadays. People have to answer how to achieve any given level and pattern of water quality in particular watercourses and also how to mitigate the catastrophes that are inseparable elements of civilization. The EU water framework directive, which came into force at the end of 2000 (Directive, 2000), changes the way of monitoring, assessing and managing water in European countries. Three groups of quality elements (biological, hydromorphological and physicochemical) have been identified in the water framework directive as necessary to classify the ecological status of a particular water body.
