Abstract

Stochastic bifurcations of the probability density of the nitrogen concentration of ammonia in the river Desna are explained as a result of the accidental coincidence of two natural processes: reduced water flow and high thermal background. The reliability of the output is about 75 %. The modeling is done with a stochastic differential equation with the control parameter.
