THE MEANING OF SOIL AND SEDIMENT COLOR: PART 2:
Using Soil and Sediment Color to Guide Field Investigations
Soil color is among the most important subsurface descriptors for hydrogeologic, environmental and geotechnical projects. Soil color does not affect the behavior of soil; however, it can indicate the composition and give clues to
- Permeability, both primary and secondary
- Water Table
- Jointing and Fracturing in Fine-Grained Sediments
- Strength, Compaction, Density/Consistency
- Stratigraphy and Facies Changes
Professionals rarely get a chance to learn about the importance of soil and sediment colors - this webinar series is designed for hydrogeologic, environmental and engineering professional who can benefit and improve project results by discovering how to apply colors to some of the most important site characterization attributes.
Munsell Soil Colors: More than just a color name
Soil colors are sometimes described using general colors, such as dark brown, yellowish brown, etc. More often and generally more acceptable, soil colors are also described and quantified by using Munsell soil color charts.
Munsell colors are quantified using a system that separates color into components of hue (relation to red, yellow and blue), value (lightness or darkness) and chroma (paleness or strength).
The importance of using Munsell soil color charts goes far beyond consistency of visual inspection. For example, many weathering zones are defined specially by their Munsell soil color designations. The water table may also be identified in low-permeable sediments by the secondary colors defined by Munsell soil colors.
