Choosing the Type of Shore Protection Structures in Reservoirs (Using the Example of the Novosibirsk Reservoir)

An increasingly urgent issue is the safety of the population, including the safety of living in the coastal zone of large bodies of water and in areas adjacent to hydraulic structures. The presence of such infrastructure facilities obligates the state to ensure their safe use for the population of the country: erecting and safely operating hydraulic structures, preventing the occurrence of emergency situations related to flooding and floodplain flooding, etc. However, adverse conditions and negative developments are increasingly occurring: dam collapses, accidents at waterworks, flooding and threats of urban areas flooding. All this directly relates to the condition of hydraulic structures (GS) and their service life; reconstruction is needed, as well as the construction of new ones. Protection of coastal areas of reservoirs is particularly important in today's world, as climate change and human impact have a negative effect on this area. One of the effective ways to protect is the use of coastal protective hydraulic structures (CPHS). The subject of study is an important part of the regional infrastructure - the Novosibirsk Reservoir, located in the Novosibirsk region and the Altai territory. The reservoir has multiple purposes (water supply, recreational and navigation). However, the coastline of the reservoir is constantly affected by various negative impacts, such as erosion, landslides, and flooding. Determining the optimal type of hydrological engineering structure for protecting the shoreline of the Novosibirsk reservoir based on analysis of existing CPHS types, their characteristics, and usage conditions is an urgent task for regions like the Novosibirsk area and Altai.
