Calculation methods of groundwater backwater in the zone of influence of hydraulic structures

Abstract

The purpose of the work is to consider methods for calculating the forecast of groundwater backwater in the zone of influence of hydraulic structures. The analysis of the analytical dependencies for calculating the forecast of groundwater backwater for various schemes. A numerical model is proposed and a computational program for calculating the groundwater backwater has been developed for a homogeneous geofiltration structure which allows discretely calculating the groundwater backwater from the canal at any time. To simplify the solution of the problem of calculating the backwater of groundwater, a computer program was created in the Python Version 3.8 programming language, which quickly solves this hydrogeological problem. A possible range of geofiltration parameters is proposed. The results of predictive calculations of groundwater backwater are the basis for assessing the zones of possible flooding - the territory within which the groundwater level rises as a result of backwatering by a hydraulic structure.

Development of the water-saving technology for refining high-viscosity watered petroleum in oilfield

“…As we improve the methodology for testing oil field treatment and water-saving demulsifiers, a special high-precision pipette was used in the study. Its use, in contrast to ordinary pipette use: increases productivity, saves laboratory chemicals and time, while the use of disposable tips allows the pipette to work with different solutions at different concentrations with the same pipette [5][6]. The improved technique has an impact on water conservation, because the highly precise dosing of the demulsifier allows the maximum possible amount of water to be extracted from the oil.…”
