River Pollution Models As An Instrument For
Basin Management
Author(s)
G. Genon
Abstract
River models are considered a useful instrument in order to assess the effects of
point and non-point loads on receiving river waters. The problem of load
allocation and definition of wastewater treatment limit can be conducted on the
basis of use of predictive models, by evaluating real verification of effects.
The structure of models, the methodology for their validation and calibration
are discussed, and the use of the obtained predictive tool is shown; applications
are presented with reference to equilibrium between benefits from improved
water quality, with lower externalities, and increased treatment cost. Also the
problem of load reduction sharing between different subjects is presented, and
attribution criteria are discussed.
Keywords: models, territorial program, wastewater, cost-benefits, externalities,
treatment cost.
1 Introduction
In order to save the quality of water resources for future generations, and at the
same time in order to allow the actual uptake for different uses, the European
Directives (in particular Directive 2000/60/EC [1]) individuated quality
standards for river waters, that can be respected in a scheduled time. The
indications of these objectives have been translated in national laws, and also
Italian law presents some examples of this application.
The Authorities in charge to program hydrologic basins destination have the
burden to fix wastewater discharge limits for municipal treatment plants, to
admit in water bodies industrial wastes with different final quality in
consideration of realised treatment, to evaluate the effects of run-off
phenomena on non-point immissions, to fix limits for agricultural use of
