A Brief Comment on Indirect Methods for Measuring Unsaturated Hydraulic Conductivity

摘要

Because of the complicated structure of unsaturated soil, direct measurement of unsaturated hydraulic conductivity in the laboratory is a very difficult process. Therefore, the indirect methods for measuring unsaturated hydraulic conductivity are widely used in practice. This paper mainly introduces the development of indirect methods, moreover, analyzes and compares the advantages and disadvantages of them briefly.
