The problems of biodiversity reduction and degradation of the running waters in the urbanized regions of Pacific Russia are relevant and require urgent solutions. However, the anthropogenic impact on changes in runoff processes, hydrochemistry, and aquatic biota of rivers located in the Far Eastern monsoon climatic zone has not been sufficiently studied so far, which makes it difficult to assess the ecological state of rivers and develop predictive models of situations arising because of an anthropogenic impact. Methods and criteria for assessing the quality of river waters in terms of chemical, microbiological and hydrobiological indicators are not adapted to regional characteristics, which often leads to conflicting results when conducting hydroecological studies. To overcome these contradictions, a long-term scientific project was initiated, aimed at developing the foundations of the system of environmental assessment (bioassessment) of the Far Eastern rivers "Development of methods for a comprehensive assessment of the ecological state of watercourses in Eastern Russia." The Muravyov-Amursky Peninsula, where the Vladivostok urban agglomeration is located, was chosen as a model territory. The article formulates the main goals and objectives of the project, provides a description of the research area and outlines the prospects for comprehensive scientific research to develop a methodology for studying urbanized rivers and express methods for assessing their ecological state.
