“…Such a structure prevents slipping of the cell filling soil (7) and protects geotextiles (5) from the negative impact. In turn, waterproof geotextiles reduce the loss of water for filtration [14]. An important advantage, determining the socio-economic feasibility of application of the developed methods to protect the structures, is the possibility of urgent elimination of violations in the structural elements without interrupting its operation in cases of emergency, that caused the failure of water conveyance structures in the vegetation period, and to reduce the possibility of damages.…”

To prolong the service life of hydraulic structures of irrigation systems and dams there were developed and patented method and device of creating impervious coating of irrigation channels, impervious geotextile coating of low-pressure earthen dams, a device for sealing butt joints of trays providing recovery of water conveyance constructions, operational reliability and durability of impervious coatings, elimination of filtration and leakage in water conveyance constructions. On channels, the result is achieved by using a two-layer coating made of geotextile with a concrete filler. To restore the operational reliability of the butt joints an impervious geotextile coating with a rubber seal is proposed to use. The reliability and durability of impervious geotextile coating for a low-pressure earthen dam are provided by a cellular structure consisting of a bed with a soil filler. Growing from the crest to the foot of the dam, the height of the bed cells eliminates the slipping of the filler which, in turn, prevents the geotextile bed from being damaged. Special attention should be paid to the activities that ensure the reliability and durability of the constructions without decommissioning them. The important task of protection and increase of exploitation safety of reclamation systems and constructions includes the application of modern technologies adaptable to various conditions of reclamation systems exploitation and structural peculiarities of reclamation technologies that provide long-term reliable protection while reducing economic and energy costs. The positive value of the net profit value (NPV) for the period of its use was adopted as a criterion for the effectiveness of the proposed technical operation.

“…The prevailing accidental defects are the complete destruction, the formation of defects that disrupt the normal facility exploitation; butt joints failure, as well as destruction of the bearing area and the interlock part. Dangerous defects causing the deterioration of operating ability in the structural elements are the formed cracks, the sizes of which exceed the limit values, the delamination of the protective layer of concrete, the corrosion of concrete reinforcement in the form of efflorescence and rusty stains [7].…”

The given article considers the necessity of implementation of new systems of technical diagnostics for a long-term exploitation of civil and industrial facilities under special climatic conditions. Currently, more than 80% of civil and industrial facilities in southern Russia have worked out their rated life. At the same time, there is a simultaneous increase in the load on aging facilities so that the absence of the necessary qualified personnel and technical repair base, will inevitably lead to an increase in the number of accidents caused by exploitation causes. The general purpose of conducting technical diagnostics is to identify the degree of physical deterioration, the deterioration causes, the actual efficiency of the elements and plans to ensure their various exploitation parameters, as well as a description of the technical condition. The most dangerous one is the risk of accidents and defects on vulnerable sites that include many civil and industrial facilities.

The withdrawal of a huge amount of water for needs of municipal and agriculture, for industry and energy production significantly affects the reduction of fish stocks and reduce the economic potential of fishery water bodies. To protect aquatic fauna, water diverting structures should be equipped with effective fish protection devices and fish protection structures. At present, a sufficiently large number of various designs of fish protection devices have been developed. However, functioning of many of them cannot be considered as satisfactory. This largely applies to water diverting facilities with a capacity of more than fifteen cubic meters per second, located on the water bodies in South of Russia, where there are rich and unique stocks of valuable commercial fish species. For fish protection structures of large water diverting facilities one of the most difficult is the task to divert the protected fish larva/young fish outside the zone of influence, which is complicated with the speed of a flow in the water intake area. Airlift pumps conform to the requirements about removing young fish to protect them, because airlift pumps do not have moving mechanical parts that might be traumatic for the fish. However, the use of airlift elevators in practice is hampered by the lack of constructive developments and methods for calculating airlifts with a small lifting height, as well as the data about survival of young when these devices are in operation. Constructions used for forced removal of protected fish should ensure the viability of fish at all stages of their movement, with high technical reliability. Options to design an airlift fish diverter have been proposed to be used in fish-protecting devices such as a floating fish-removal line. The rationale to use the airlift elevator as a power plant aimed at removal protected young fish from fish protection structures is provided. We reported about some observed damage caused to fish during their contact with fish protection and fish removal constructions. The necessary conditions, which should be met in order to avoid injuring the protected young fish are described; the results of the study on young fish in the airlift fish elevator are introduced.
