Bureau of Hydrology, Ministry of Water Resources, Beijing 100053, China)Abstract: Considering the characteristics of water dynamics in medium鄄 and small鄄sized rivers and pollutantemission in sudden water pollution accidents, the pollution source was generalized as a discontinuous sourcedistributing over a time period.Based on the one鄄dimensional convection鄄diffusion equation and observationinformation of the time sequence of pollutant concentration in a downstream section where the accidents happened,an inverse problem of the source intensity change process in sudden water pollution accidents in medium鄄 and small鄄sized rivers was established, and a mathematical method for solving this inve...
