Securing of temporary hydrotechnical structures (water-filled, panel-mounted, and other types of dikes) of dif- ferent heights by means of flat earth anchors and screw piles designed to protect population centers and infra- structure against large-scale floods is considered. Keywords: low riverside dikes; flat earth anchors; screw piles; soil mechanics; burial in ground; rope system; support pillars. Flooding is among the most dangerous and most frequent type of natural disaster occurring annually around the world. According to the definition of the hydrological scientist R. A. Nezhikhovskii, “Flooding involves the submergence of land adjacent to a river or sea by water that causes material losses, harms the health of the population or leads to death of human beings” [1]. The massive floods of 2017 in India (state of Assam), the United States (state of California), and Mexico (state of Tamaulipas) along with those in Russia (Stavropol kray, Tyumen and Amur oblast’s) correspond fully to this definition. Long-term flooding introduces significant ecological and economic damage and is accompanied by large-scale death of animals and crop failures, destruction of farm crops and plants, and the destruction of industrial and civil structures [2, 3]. In a flood period polluted water fills coastal land, washes away dumps and burial grounds for animal refuse, cemeteries, and other potentially dangerous facilities, which represent a serious epidemiological danger to the local popu- lation for a prolonged period. Government agencies employ a number of different methods of protecting population centers and infrastructure against floods based on available technical capabilities and organizations in order to minimize losses caused by natural disasters. Simply put, these methods may be divided into permanent and temporary [4]. The permanent methods of protection include regulation of river flow by means of al- ready constructed structures, such as dams, hydroelectric sta- tions, and reservoirs. Temporary methods of protection are based on timely prediction and reporting of the scales of im- pending floods and include measures for the construction of temporary hydrotechnical structures and protective build- ings. Permanent hydrotechnical structures may be effectively complemented with temporary protective structures erected on low-lying ground sections of the region to assure compre- hensive protection of adjacent lands and effective regulation of river discharge even in the case of large-scale floods last- ing several weeks or even months. In most cases temporary hydrotechnical protective sys- tems are installed over the entire anticipated period of the flood and are dismantled right after the water level falls, which makes it possible to minimize the adverse technical ef- fects of these systems on the region and surrounding ecosys- tem. As a result water-filled protective dikes and protective gate dikes have become widely used as temporary systems in recent years. The rapid development of modern technologies has made it possible to use increasingly stronger, more light-weight, wear-resistant, and flexible materials in the creation of wa- ter-filled and protective dikes, which in the future will make it possible to increase their reliability and overall dimen- sions. Trends towards the use of new materials and protec- tive structures are growing and advances in this field are con- firmed by a series of patents for new inventions [5 – 11]. There exists a host of technical problems in the case of both existing water-filled and protective dikes and newly devel- Power Technology and Engineering Vol. 52, No. 4, November, 2018 405 1570-145X/18/5204-0405 © 2018 Springer Science+Business Media, LLC 1 Russian State Agrarian University — K.
