The research complex addresses the actual scientific and practical problem of studying the technical condition and filtration losses of water from the regulating pools and channels of irrigation systems.

The dependence of electromagnetic radiation upon alternating loading in dry and moist conditions in specimens of loess clays and clays was experimentally established. A method for determination of zones of filtration deformations and water losses by complex application of geophysical methods of natural pulsed electromagnetic field of the Earth (NIEMFE) and vertical electric sounding (VES) is offered and substantiated, which allows to determine qualitative parameters and sizes of disturbed areas.

The method of calculation of quantitative indicators of water filtration losses has been improved and a simplified calculation algorithm, which is an applied application of Darcy’s law, has been proposed. Investigation and establishment of dependence between the geological features of the location of the object and the level of its technical condition and unloading of filtration flows, which affects the hydrogeological regime and the ecological and ameliorative status of the adjacent territories.

The necessity of localization of sites of filtration losses of water in order to concentrate repair and restoration works in the most disturbed zones is scientifically substantiated, which will allow to significantly reduce the time and costs and increase the overall efficiency of the structure.
