Who developed a method for describing the effect of soil moisture on fine-grained soils?

• A. Karl Terzaghi
• B. A. Atterberg
• C. Albert Atterberg
• D. Henri Dutrochet

Answer: (C)

The individual recognized for developing a method to describe the effect of soil moisture on fine-grained soils is Albert Atterberg. His work led to the formulation of the Atterberg limits, which include the liquid limit, plastic limit, and shrinkage limit. These parameters are critical in classifying the behavior of fine-grained soils under varying moisture conditions. The Atterberg limits provide insight into the consistency, plasticity, and overall engineering characteristics of these soils, which is essential for construction and soil stabilization purposes.

Understanding the impact of moisture content on the physical properties of fine-grained soils is vital in geotechnical engineering, as it affects soil strength and stability. Albert Atterberg's contributions continue to be a fundamental part of soil mechanics, demonstrating the importance of moisture in determining soil behavior.
