Study of the "aquifer-well" geotechnogenic system using precision observations at the water intakes of Tyumen region

Abstract

An express research method is presented for studying the geotechnogenic system "aquifer-well" in solving problems of hydrogeology. The express method is based on the use of precision water level measurements. The scope of its application and relevance in modern conditions аre shown. Express pumping was performed at water bodies of Tyumen region, where an assessment (revaluation) of fresh underground water reserves was carried out. A comparative analysis of the results of express and traditional methods showed good convergence. The use of express pumping in the practice of hydrogeological research on small water bodies is the only tool for obtaining raw materials for the calculation (recalculation) of fresh groundwater reserves and makes it possible to reduce material costs when performing pilot filtration work. The recording of changes in the values of the conductivity coefficient by means of precision measurements of the water level during express pumping in monitoring studies allows you reliable and timely detection of changes in the filtration medium.
