Abstract: Rivers are the cheapest and the most common receptor of pollutant discharge.While the need todischarge the ever increasing quantities of the various domestic,industrial and agricultural wasteresiduals into rivers puts ever increasing pressure on their waste assimilating capacity,it becomesincreasingly difficult to ensure that concentrations of various contaminants will remain below thelimits dictated by a variety of competing uses.If the capacity of a river to transport,disperse orassimilate a contaminant is over estimated,serious pollution may result.Under-estimation,on theother hand,may mean that a valuable resourceis not optimally utilized,resulting in great expenditurein treatment facilities.Virtually,no water quality management study which is aimed at achievingoptimum usage of a river system can bypass the need for a reliable means of predicting the dispersioncharacteristics of the water bodyAlso,when there are accidental discharge of dangerous material,weurgently need to reliably estimate the location and concentration of the contaminant cloud.
