ЗОНАЛЬНОСТЬ ВНУТРИГОДОВОЙ НЕРАВНОМЕРНОСТИ ЭРОЗИИ И СТОКА ВЗВЕШЕННЫХ НАНОСОВ В БАССЕЙНАХ МАЛЫХ И СРЕДНИХ РЕК ВОСТОЧНОЙ ЕВРОПЫ (ПОСВЯЩАЕТСЯ 200-ЛЕТИЮ КАЗАНСКОГО ГОСУДАРСТВЕННОГО УНИВЕРСИТЕТА)

Abstract

On the base of long-term observation of suspended sediment yield in the river basins of Eastern Europe the seasonal irregularity of erosion having zonal features has been revealed. It grows along with aridity of climate, i.e. from forest zone to semidesert. The human impact complexifies this tendency: irregularities of erosion and suspended sediment yield increase with growth of land reclamation within the river basins. This influence is more distinct in the forest zone. The annual changes of suspended sediment yield are less intensive in the big basins.
