Method for Determining the Filtration Coefficient Based on Changes in the Thermal State of the Dam Foundation

In this study, the changes in groundwater temperature at the base of the future dam of the Rogun hydropower plant are studied, with the aim of assessing the filtration characteristics of the base rock and determining the filtration coefficient and concentrated filtration path. In addition, the equation for the filtration coefficient is derived, which is used to calculate the filtration coefficient and rate of the filtered turbulent water movement.
