Geologic and geomorphic control over the channel-forming activity of the Maritime territory rivers

Abstract

Geologic and topographic features of the Maritime territory control the loose material volume which comes from slopes to valleys floor as well as conditions of channel deformations development and floodplain-forming processes. Three types and eleven sub-types of curves of the channel-forming discharges are distinguished according to geologic and geomorphic conditions of the drainage basins and order of streams. The data obtained permit to approach prognosis of changes in rivers channel-forming activity by way of model ling of changes in conditions of channel deformations and floodplain-forming processes while the drainage basins topography assumed to be invariable.
