Scope of Work
1. Analysis of Engineering Survey Materials
A comprehensive review of baseline engineering data was performed, including:
-
geodetic surveys (topographic surveys and digital terrain models);
-
engineering-geological and hydrogeological investigations;
-
hydrometeorological data and design hydrological parameters.
The completeness, reliability, and adequacy of the source data for hydraulic structure design were assessed.
2. Review of the “Hydrological Report” Section
Hydrological calculations for the reservoirs were verified, including:
-
design discharges and water levels;
-
flood parameters for various exceedance probabilities;
-
water balance assessments;
-
evaluation of climate change impacts on water availability.
The correctness of applied methodologies and compliance with regulatory standards were reviewed.
3. Assessment of Hydraulic Engineering Design Solutions
A technical review of structural and engineering calculations was conducted, including:
-
seepage and filtration analyses and drainage system design;
-
slope stability calculations;
-
stress-strain analysis;
-
settlement and horizontal displacement assessments;
-
slope protection against wave and ice loads.
The reliability and long-term performance of the proposed structures under both design and extreme loading conditions were evaluated.
4. Review of the Instrumentation and Automation (I&C) Section
An assessment was carried out of automated water accounting systems and technical monitoring solutions for dams, embankments, and spillway structures, including:
-
justification of equipment selection;
-
instrumentation layout schemes;
-
monitoring programs;
-
technical specifications;
-
review of cost estimates.
5. Recommendations on Instrumentation Completeness and Equipment Configuration
Recommendations were developed to:
-
enhance monitoring system reliability;
-
optimize equipment configuration;
-
ensure comprehensive control of seepage and deformation processes;
-
improve automation levels for water accounting.
Project Outcome
The technical review confirmed the overall soundness of the proposed design solutions, identified potential risks, and provided recommendations to enhance structural safety and climate resilience.
The results contribute to the safe operation of reservoirs and the sustainable development of water management infrastructure under changing climate conditions.
