Problems and ways for solving issues of engineering protection and restoration of coastal disturbed lands of urban territories

The problems of engineering  protection of territories from flooding and flooding by flood waters of rivers are relevant  for many  regions of Russia, including for the Moscow region, where the project of creating  the  science town  «Big Serpukhov» is being  implemented. At  the  same  time,  serious  obstacles arose related  to the flooding  of a significant part  of the territories  of the coastal  zones of the Serpukhov region. Here, most of the agricultural land is in a disturbed and degraded state, it needs to be restored using phytomeliorative measures.  In order to solve the problems and obstacles that have arisen, scientific programs have been drawn up to study  and  survey  the existing  state  of all territories  and  objects of the science city being formed. And also – water bodies (Oka and Nara rivers), which are sources of flooding of coastal areas and  settlements. The results  of the analysis of materials previously  made  by the authors of developments and   inventions  on  the  engineering   protection   of  coastal   territories   and   objects  are  presented   from the point of view of the possibility of their use in solving the problems of flooding the lands of the science city. The developments and inventions that  can be effectively used in solving the issues of engineering  protection and environmental arrangement of the flooded territories of the science city are briefly demonstrated. The results of preliminary studies  confirm the high efficiency and manufacturability of the use of bioengineering systems for the  protection  and  development of coastal  zones.  The  creation  and  implementation of bioengineering systems  based on natural and safe artificial  materials will reduce the material costs of construction and will contribute  to the restoration  of water protection and other disturbed zones in compliance  with environmental requirements. A preliminary assessment of the impact  of the dam  on the Nara  River  in a hydrodynamic accident  on the parameters of the flood zone in the left-bank part of the clusters  and districts of Serpukhov showed that in the implementation of the most likely accident scenario, the emergency situation may be local in terms of material damage and municipal in terms of territoriality.
