- Аннотация: The SEA/Balance (soil erosion–accumulation balance) model and the WATEM/SEDEMmodel both mapping the erosion–accumulation budget of sediment within river basins were testedfor 11 river basins of the eastern Russian Plain. The dynamics of river sediment yield were evaluatedwithin one of the river basins. The analysis is based on observations of suspended sediment yieldin test river basins with an area ranging from 100 to 1500 km2. The maps of the average annualerosion–accumulative budget of sediment were constructed using two methods, making it possible toquantitatively assess the amount of sediment yield from the catchment area for the river basins understudy. The WATEM/SEDEM model and the author’s SEA/Balance model were used for sedimentyield estimation. The results of calculation using the WATEM/SEDEM model have an average biasof +11% compared to observed suspended sediment yield. The corresponding value in the caseof the SEA/Balance model application is −29%. SEA/Balance model assessment sediment yielddynamics for the Sterlya river basin show an 11 percent reduction. It is possible to conclude that theproposed method of SEA/Balance can be applied to river basins of the agricultural zone of the eastRussian Plain.
