State of natural and technical system of the Gruzskoy Elanchik River basin of the Donetsk People’s Republic

Introduction. In 2024 the President of the Russian Federation has instructed to approve the Strategy for the Sustainable Development of the Azov Region until 2040 and the action plan for its implementation, ensuring the synchronization of decisions on the financing of these activities with national projects and strategic planning documents; significant plans are connected with this, including improvement in living standards in the Azov region. This strategy, among other things, is aimed to develop beach tourism, as well as well as the fish industry with a great potential of the Azov Sea. In this regard, we are carrying out this research, focusing on studying the current geoecological state of the river basins of the Northern Azov hydrological region as exemplified by the small river Gruzskoy Elanchik (L = 91 km, F = 1,250 km2). Aims for the selected river basin are the following: create databases of construction and urban facilities in the basin of the Gruzskoy Elanchik river containing structural parameters, its functional purpose, morphometric features, geomorphological features, physicochemical water specimens.

Materials and methods. The work is based on factual material collected in the field research in the basin of the Gruzskoy Elanchik River. The analysis of the design, construction and operational documentation of the complexes of structures along the riverbed were carried out, their structural elements were evaluated; water specimens were taken for complex laboratory studies.

Results. Gradation schemes for reclamation and water management facilities have been developed for the selected river basin. Geoinformation databases including spatial data have been created.

Conclusions. Data were collected to determine the degree of environmental safety, compiled based on the results of a field survey, systematizing information about water management construction facilities in the river basin: studies of operated water management and reclamation construction facilities were conducted; certified devices and equipment were used to ensure the accuracy and reproducibility of the results; the data obtained were analyzed and the results evaluated; the assessment of the technical condition and safety level, according to the current codes and rules, was given at the moment of examination; recommendations on carrying out a set of measures to strengthen the safety of structures were given.
