Lecture
This lecture covers hydraulic testing in soil mechanics, focusing on Dupuit theory. It explains the general concepts of water capture, free and confined aquifers, and pumping wells. The Dupuit theory, developed by Arsène Jules Emile Juvénal Dupuit, is explored, emphasizing its application to groundwater hydraulics. The lecture discusses the assumptions of Dupuit theory, including porous, homogeneous, and incompressible media, as well as the conditions for steady flow. It delves into specific scenarios such as free aquifer between trenches, captive aquifer, and pumping wells, providing derivations and practical implications. The lecture concludes with a recapitulation of Dupuit's formula and its application to different hydrogeological settings.
