Permeability Testing in Soil Mechanics

This lecture covers hydraulic tests in the field and laboratory, focusing on pumping tests and permeameters. It explains the objectives of pumping tests, such as characterizing aquifers and wells, and introduces theories like Dupuit's for steady flow. The lecture also details the process of pumping tests, emphasizing the importance of reaching a stable regime. Additionally, it discusses Theis' theory for transient flow tests, including assumptions and procedures for determining transmissivity and storage coefficient. Laboratory permeability tests are also explained, highlighting the use of constant and variable head permeameters. The lecture concludes with the application of Theis' formula and the interpretation of test results through logarithmic representation.
