What you mean by cohesive and non-cohesive soil?
cohesive soils are those soils where the attraction between the soil particles is very high such as in clay. non-cohesive soils are those soils where there is no firm attraction between the soil particles.
What are some examples cohesive soils?
Some examples of cohesive soils include clay, silt, and loam. These soils have fine particles that are able to stick together due to their cohesive properties, which can make them prone to retaining water and forming stable structures.
Why cohesive soil is a better foundation than that of non-cohesive.?
Cohesive soils, like clay, exhibit greater strength and stability compared to non-cohesive soils, such as sand. They have a lower permeability which can help in preventing seepage and erosion, making them suitable for foundation construction. Cohesive soils also typically experience less settlement over time, providing a more stable base for structures.
What soils most easily erode soils with a high sand content or soils with a high clay content?
Soils with a high sand content are more prone to erosion compared to soils with a high clay content. This is because sand particles are larger and less cohesive, making them more easily detached and transported by water or wind. Clay particles are smaller and more cohesive, providing better resistance to erosion.
Are soils with high Sand content more prone to become eroded verses clay content?
Yes, soils with high sand content are generally more prone to erosion compared to soils with high clay content. This is because sand particles are larger and less cohesive, making them easier to displace and transport during rainfall or wind events. Clay particles, on the other hand, are smaller and more cohesive, which helps them retain water and resist erosion.
What is the optimum moisture content of soil?
The water content corresponding to the maximum dry unit weight or maximum dry density is know that as optimum moisture content.(o.M.c.) or optimum water content (o.w.c) maximum dry density is achieved at higher O.M.C.for cohesive soils or fine grained soils s compared to cohesionless soils.(sand 6-10%0

What is hydraulic conductivity of soil?
This depends on the soil! Cohesionless coarse grained soils with high gravel contents may have high hydraulic conductivity on the order of 1 to 1x10-1 m/s. Mixed sands and gravels are on the order of 1x10-1 to 1x10-3 m/s. Finer sands approximately 1x10-3 to 1x10-4, and fine grained soils such as silty sands may be in the range of 1x10-5 to 1x10-7 m/s. Very fine grained cohesive clay soils have very low hydraulic conductivity values ranging from 1x10-7 to 1x10-13 m/s.
How do sientists classify soil?
The US Occupational Safety and Health Administration (OSHA) uses 5 soil classifications: Stable Rock Type A - cohesive, plastic soils with unconfined compressive strength greater than 1.5 ton/sf Type B - cohesive soils with unconfined compressive strength between 0.5 and 1.5 ton/sf Type C - granular or cohesive soils with unconfined compressive strength less than 0.5 ton.sf Type C60
Would Granular soil or cohesive soil be greater runoff?
cohesive soil would have more runoff since the water would be less likely to seep past the surface layer. On granular soils, the passage ways are larger and the water can quickly seep into the structure of the soil.
What are the problem soils and their reclamation?
Problem soils include saline soils, sodic soils, acidic soils, and compacted soils. Reclamation methods vary depending on the type of problem soil but can include adding soil amendments like gypsum for sodic soils, lime for acidic soils, and organic matter for compacted soils. Drainage improvement and crop rotation are other common strategies for reclaiming problem soils.
