Water transported soils are termed
Colluvial
Aeolian
Lacustrine
Alluvial
Alluvial
Alluvial soils are soils transported and deposited by flowing water, such as rivers and streams. These soils typically exhibit stratification and are categorized based on the source and energy of the water flow.

vтИЭdтАЛ тАФ where v is the critical velocity and d is the particle diameter, governing transport capacity.
The process begins with the weathering of parent rock, followed by erosion through fluid kinetic energy. As the velocity of the water decreases, the carrying capacity drops, causing the suspended particles to settle in stages according to their size and weight, leading to sedimentary layer formation.
Alluvial soil is formed by river action.
Aeolian soil is transported by wind.
Lacustrine soil is deposited in lake beds.
Colluvial soil is deposited by gravity at the base of slopes.
Generally highly fertile and suitable for agriculture.
Usually covers large areas in river valleys and floodplains.
Can be highly compressible, posing risks for heavy foundation construction.
Variable particle distribution can lead to differential settlement.
Agricultural development.
Foundation engineering in river basin zones.
Option A (Colluvial) refers to gravitational transport.
Option B (Aeolian) refers to wind-deposited soil (e.g., loess).
Option C (Lacustrine) refers to deposition in quiet water bodies like lakes.
D is correct тАФ Alluvial soil is defined as soil that has been transported and deposited by running water.
Remember the suffix '-ine' often relates to water (e.g., Lacustrine for lakes, Marine for seas), whereas 'Alluvial' specifically implies riverine activity.
