The water sector in Syria suffers from longstanding problems and faces many challenges in terms of water supply and quality sanitation. These challenges include water scarcity, increasing water demand due to population growth and conflicts in the region, rapid urbanization, water pollution, limited access to drinking water and sanitation in rural areas, inefficient water distribution system in addition to constant network failures, as well as lack of financial resources, inefficient water pricing system and methods, cost recovery and asset management. As a result, the need for a significant quantitative increase and qualitative improvement of engineering infrastructure facilities (water supply and sanitation systems) and parts of distribution networks, in addition to the technical capabilities and development of resource management methods, which in turn leads to improved management of water supply and sanitation systems and the welfare of the population in the region, clearly becomes apparent.

The development, development and reorganization of territories for civil construction projects is often associated with problems of control and protection against erosion processes. Territories previously considered inconvenient are now subject to intensive development. The investment attractiveness of such territories is very high, so it is necessary to carry out engineering preparation measures, including those to protect it from erosion processes. Studies show that the most environmentally friendly structures to prevent erosion processes are geocomposite systems created on the basis of anti-erosion geosynthetic materials. But before applying any measures to stabilize erosion processes, it is necessary to understand the process of interaction between the methods used and the surfaces to be protected. The article considers the zoning of coastal slopes, as the most vulnerable to the impact of erosion of territories in cities, on non-flooded, partially flooded and permanently flooded zones. Accordingly, this division was made in order to determine the possible impacts on the structures of geocomposite systems. Each impact (hydraulic, snow, ice) is described using mathematical modeling, indicating methods for calculating the stability of the geocomposite system for the zones identified in the study. It has been established that the strength of a geocomposite system also affects its stability, therefore, when determining the overall stability of a geocomposite system, the concept of its tensile strength is introduced. The presented materials are of great importance in practical application. This is due to the reduction of material and labor costs for the implementation of anti-erosion protection measures when applying the results of this study. Further research is aimed at optimizing the design of anti-erosion protection based on geocomposite systems in order to organize their mass production and create standard industrial designs.

The use of clayey soils in the construction of subgrade allows to reduce the use of sandy soils, thereby reducing the number of quarries formed. However, this requires the implementation of constructive measures aimed at ensuring reliability, strength and safety. One of the ways to implement such activities is the use of geosynthetic materials. In the article, based on the experience of designing and building objects with geosynthetic materials, the criteria for choosing their types depending on the tasks being solved are established. The necessity of developing a mathematical model substantiating the decisions taken is considered. The obligatory organization and conduct of geotechnical control is noted as a tool to determine the directions for the development of this area of ​​construction in order to reduce the technogenic load on the territories associated with the withdrawal of natural resources.
