Concentration Profiles Of Pollutants In A River
Basin: An Application To The Sarno River
Author(s)
M. Di Natale
Abstract
A simplified numerical model to evaluate the concentration profiles of
reactive pollutants in a natural river system is presented.
The model, subdivided in several calculation forms, provides, first of
all, of a geometrical schematisation of the system in a linear branch and basins
with an elementary shape, in such a way as to deduce easily the flows per unit
width in the system, in the flood, low level and ordinary conditions.
Assuming the hypothesis of hydraulic flux in uniform motion, and
subdividing each branch of the system into stretches of elementary length, every
stretch is regarded as a chemical dispersion flux reactor, for which a simplified
analytical expression of concentration profile is deduced.
An example of application of the proposed model for the case of the
