RIBEIRO, Celso B. de M.; SILVA, Demétrius D. da; SOARES, José H. P. e GUEDES, Hugo A. S.. Warning system based on theoretical-experimental study of dispersion of soluble pollutants in rivers. Eng. Agríc. [online]. 2011, vol.31, n.5, pp. 985-997. ISSN 0100-6916. http://dx.doi.org/10.1590/S0100-69162011000500016.
Information about capacity of transport and dispersion of soluble pollutants in natural streams are important in the management of water resources, especially in planning preventive measures to minimize the problems caused by accidental or intentional waste, in public health and economic activities that depend on the use of water. Considering this importance, this study aimed to develop a warning system for rivers, based on experimental techniques using tracers and analytical equations of one-dimensional transport of soluble pollutants conservative, to subsidizing the decision-making in the management of water resources. The system was development in JAVA programming language and MySQL database can predict the travel time of pollutants clouds from a point of eviction and graphically displays the temporal distribution of concentrations of passage clouds, in a particular location, downstream from the point of its launch.
