Environmental impact assessments and their importance for ensuring water security

\nThis article is devoted to the procedural institute of environmental expertise of water objects, which has relatively recently received a residence in the domestic legal proceedings. Restoration of certain places requires considerable time, carrying out expensive reanimation works. Predictive activity and elements of propaedeutics become an important track in preservation of environmental safety. Specialized knowledge is required to solve such objectives. Complexity of studying of water bodies, their connection with other resources makes the format of complex hydro-ecological expertise in demand. Representatives of natural and applied sciences are involved. As a result, we get synthetic conclusions, which can be used in evidence. Theory recognizes the importance of this type of analysis, but the methodological basis for it has not been properly developed. Practice articulates the need for such research. The introduction shows the complexity of organizing and conducting environmental expertise of water bodies, the scope of analytical and empirical objectives is outlined. In the course of the description of materials and methods of research, conclusions are formulated about the demand for a particular format of research, prospects for its use in proving criminal, administrative and civil cases. The idea about the difficulty of defining the expert objective in the assigned segment is substantiated, as there are no clear ideas about the possibilities of science in this special field. The methodological basis for the study of the highlighted moments is based on the combination of axiological aspects and systemic principles with the application of the activity trajectory. The methodological block reveals and substantiates the most effective means and ways of this kind of research for the purposes of identification and investigation of environmental crimes; consideration of civil law disputes related to water objects. The discussions formulate the problems of development of this type of expertise, with proposals to overcome them.\n
