Abstract

A numerical simulation model was presented to describe the material cycling along a river, in which the longitudinal cross-section of the river was divided into 4 segments (segment M, 1, 2 and 3, respectively), and the external supply, decomposition and transport of coarse particulate organic matter (CPOM) were taken into account to represent the longitudinal material and energy transports in the river ecosystem. The numerical simulation was performed under the ordinary discharge condition for 4 years. The results of the simulation show that the large amount of CPOM accumulates in the river bed at the upstream area of the river, which acts as an important source of PO₄-P and NO₃-N in downstream area of the river.
