DISPRIN is a new model of dispersion has been developed to simulate the impact of pollutant discharges on river systems. The model accounts for the main dispersion processes operating in rivers as well as the dilution from incoming tributaries and first-order kinetic decay processes. The model is dynamic and simulates the hourly behaviour of river flow and pollutants along river systems.

A new model DISPRIN has been developed to simulate dispersion processes in the River System. The model takes into account dispersion, mixing, dilution and decay processes affecting discharges.

The model has been applied to the Mures River systems to assess impacts of accidental dam or mine releases on water quality downstream. The model has been applied to the Mures River systems to assess impacts of accidental dam or mine releases on water quality downstream. The Figure to the right shows the simulated impacts of a discharge on the river water quality.
