摘要：

Spatiotemporal peculiarities of terrigenous sedimentation in the second part of the XXth century are analyzed on the basis of balance calculations with the application of a spatially detailed mathematical model of transport and sedimentation of suspended matter adjusted for the Sea of Azov. The setup and calibration of this model are described and an interpretation of the results is carried out. According to climatic fluctuation and anthropogenous activity, four periods of terrigenous sedimentation in the second part of the XXth century are determined. The schemes of deposition and erosion sediment matter are made. The general tendency of a decrease in terrigenous matter accumulation and an increase in the squares of negative balance of terrigenous matter is caused by a 2.5-fold reduction of volume in the transported land matter. In the study period, the intensity of sedimentation decreased from 1000 to 400 g/m(2) per year.
