Abstract: The CONDOR program allows the computation of CONvection, Diffusion and/Or Reaction of several pollutants in looped river networks. The transport of pollutant is modelled after an accurate computation of the unsteady flow in the network which plays a major role. The methods used are precise so as to avoid numerical errors; in particular the resolution of convection makes use of a cha- racteristics method associated with interpolation of the 4th order at the foot of the characteristic curve. However, these methods are also designed to give maxi- mum reliability under widely varying modelled situations (branches, loops, hy- draulic structures, tidal flow, etc. ). Simple cases show the accuracy of the methods and a fictive study is presented to illustrate the potential of the program.
