Purpose: to provide a scientific justification for the accepted engineering solutions for bank protection of the Dagomys River section in Dagomys (Sochi) settlement through a comprehensive analysis of engineering survey data and design documentation, taking into account natural conditions, and to develop recommendations for maintenance of facilities, including the concept of a software tool of decision support based on predictive modeling.
Materials and methods. To ensure the reliability of class III waterworks (gabions and pile walls) under conditions of high seismicity, floods, erosion, and man-made impacts, a comprehensive monitoring program was developed. This program includes systematic defect monitoring, assessment of compliance with design parameters, and prediction of structural behavior using mathematical deformation models.
Results. Monitoring indicators are based on mathematical models that take into account local factors: sandy-pebble soils with a high groundwater table (0.8–1.2 m), seasonal floods (H = 2–3 m, 25–30 % annual probability), and seismicity. The results of monitoring the bank protection structures on the Dagomys River (type 1 gabions and type 2 pile wall) formed the basis for recommendations for technical maintenance and repair. All work is carried out during low-water periods with quality control, ensuring seismic resistance and a service life of ≥ 50 years. To optimize operation, a web module written in Python/Flask with the Pandas, NumPy, and Plotly libraries is proposed: data centralization, automated checks (comparison with К₁/К₂), trend analysis, visualization (graphs, maps).
Conclusions. Measures to ensure the durability and reliability of constructed structures were proposed. Recommendations for monitoring the bank protection structures condition were developed. Key control parameters for each type of structure were identified. The need and concept for a Python software module to support decision-making by the maintenance service was substantiated.
