: How the presence of water in soil affects the property of soil and its load-carrying capacity? Also, mention how the seasonal variation of the water content of soil will affect the settlement characteristics of the foundation?

In soil water is exerting buoyancy force on soil particles due to which wight of soil is reduces and behaviour of soil is also changes due to presence of water.

As we know soil is made of some minerals and either soil particles are bonded together by cohesion or frictional resistance or both. When water filled in pore of the soil then water can react with these minerals or it can reduces the frictional resistance or cohesive force and property of soil get changed.

Due to decrease in weight of soil bearing capacity of soil is also changed, due to decrease in bearing capacity of Soil it's load carrying capacity is also decreases.

Due to seasonal variation soil is saturated alternately and there are some minerals which is swelling and shrinking alternately. Due to theses swell and shrink alternately there can be settlement of foundation occures.

comment for any doubt about this solution thank you
