Abstract

According to the hydrodynamic characteristics of a wide and shallow river and the transfer characteristics of soluble pollutants, an inverse problem of instantaneous source in a wide and shallow river is established to confirming the pollution source intensity and location. A mathematical solving method is set out by using a differential evolution algorithm. A typical case is set out and the solving method is verified by a two-dimensional theoretical solution. Based on the scene analysis method, further analysis is made to analyze the influence of monitoring sites, monitoring frequency and monitoring accuracy on inversion accuracy. Keywords: wide and shallow river, instantaneous pollutant source, source intensity, inverse problem, inversion accuracy.
