Assessment of problematic sections of raft transportation on the Verhnyaya Kama river from Bondyug village to Solikamsk caused by riverine deformations and ways to eliminate them
The analysis of channel deformations of the limiting sections of rivers is the basis for choosing a scheme for radically improving navigable conditions on them. The studies of longitudinal and planned long-term deformations causing difficulties for navigation have been carried out on the example the Verhnyaya Kama on the section from Bondyug village to Solikamsk The characteristics of the sections difficult for navigation from the village of Bondyug to Solikamsk are given. The main trends in the development of the channel along the sections within the boundaries under consideration and the intensity of channel deformations are set. The nature of long-term deformations is very diverse. The entire area is divided into short periods of sediment accumulation and longer periods of erosion. On the basis of the performed analysis of long-term channel deformations, a set of track works was proposed, including dredging and erection of corrective structures that contribute to the elimination of problematic water nodes.
