METHODS FOR DETERMINING THE HYDRAULIC CONDUCTIVITY OF SHALLOW DRAINAGE SYSTEMS DURING OPERATION

Oleg Tyshchenko

The article examines modern laboratory, field, geophysical, and numerical methods for determining the hydraulic conductivity of shallow drainage systems. A comparative analysis of the methods is conducted, taking into account accuracy, cost, ease of implementation, and application range. Foreign experience in the use of these methods in the USA, Canada, and Europe is presented. Examples of integrated applications to improve the accuracy of hydraulic conductivity assessment are provided. The results of the study can be used for the design, monitoring, and optimization of drainage systems in construction and engineering practice. The study shows that laboratory methods provide high measurement accuracy but are limited by sample size and testing conditions. Field methods allow consideration of natural soil heterogeneity and seasonal fluctuations in groundwater levels. Geophysical methods make it possible to assess large areas and deep soil layers without disturbing the environment. Numerical modeling integrates data from various sources and allows prediction of drainage system performance under different scenarios. Examples of integrated method application are provided to reduce maintenance costs and improve water drainage efficiency. The article emphasizes the importance of a comprehensive approach to ensure long-term stable operation of drainage systems. Additionally, the cost and efficiency of each method are evaluated, enabling engineers to make economically sound decisions. Examples of method application in different soil types and climatic conditions are presented. The combination of laboratory, field, and numerical methods is discussed to enhance prediction accuracy. The article also considers the prospects for implementing modern technologies and automation in measurements to optimize the process of determining hydraulic conductivity in shallow drainage systems
