This free online course on various Suction Measurement Techniques for Unsaturated Soils, starts by explaining the concept of soil water potential. You will be informed on the concept of the Soil-Water Characteristics Curve and the water retention of unsaturated soils. You will then be introduced to Dallavalle's Theory and its application in the Soil-Water Characteristics Curve.
Next, you will be introduced to the Hydraulic Conductivity Function and the application of Darcy's law. You will then learn how to estimate the hydraulic conductivity of soils. Further, you will learn about the techniques for measuring and controlling the total or matric suction of soils. The working principles of the various techniques will also be explained.
Learning about the suction measurement techniques for unsaturated soils, will help build your background in understanding the shear strength and behaviour of unsaturated soils. If you are looking to be more professional in your geotechnical engineering career or build on your already existing knowledge of the various suction measurement techniques, this course is for you.Start Course Now
