GENERAL CONSIDERATIONS OF GROUNDWATER MOVEMENT

<p style="text-align: justify;">Groundwater motion is a specific case of fluid motion in a porous medium and is called filtration. Such movement is encountered in the most diverse fields of technology: in hydrotechnics and land reclamation, in water supply and sewerage, in the exploitation of oil, in foundries (gas filtration through mold material) and the like. Filtration plays a particularly important role in hydraulic structures. Knowledge of the movement of subsurface flows makes it possible to address such issues as, for example, stability of soil, concrete and other barriers (dams), filtration from canals, groundwater position after canal construction, irrigation and drainage of soil by open channels, drainage, inflow into artesian and ordinary wells etc. The paper presents the hydraulic approach of consideration without hydrogeological consideration of this problem.</p>
