MAP OF CHANNEL PROCESSES AND THEIR CHANGES UNDER HUMAN IMPACT ON THE CRIMEA RIVERS

For the first time, a large-scale map of channel processes on rivers of the Crimean Peninsula is created, the territory of which in its natural conditions and anthropogenic impact significantly differs from other regions of Russia. The connection between channel and floodplain morphology and riverbed sediments with geological, geomorphological and hydrological natural conditions is reviewed, as well as with the strongest human impact dating back to the 4th century BC and associated both with water intake and with technogenic transformation of river channels. Six regions of the Crimea Peninsula, differing in the conditions of channel formation and channel regime, are marked. The data on the length of rivers, their slopes, river channel changes, flood regime and mudflow activity, on the hydraulic engineering measures (river canalization, bank protection, creation of water reservoirs, etc.) is provided. The analysis of research results, including the created map, determined the need to study the influence of massive human intervention on the conditions of river channels formation in order to prevent or neutralize its negative environmental consequences.
