How does soil texture influence infiltration capacity?

• Soil texture has no impact on infiltration

• Fine-textured soils allow faster infiltration

• Coarse-textured soils have higher infiltration rates than fine-textured soils

• Coarse-textured soils have lower infiltration rates than fine-textured soils

True or False: Rainwater infiltration rates in agricultural fields are typically higher than in undisturbed forest land.

• True

• False

How does soil particle size distribution affect infiltration?

• Coarse particles allow higher infiltration than fine particles

• Fine particles allow higher infiltration than coarse particles

• Particle size does not affect infiltration

• Smaller particles increase infiltration

Vegetation on the soil surface affects infiltration by:

• Reducing infiltration

• Preventing infiltration

• Having no effect on infiltration

• Increasing infiltration by slowing runoff and allowing absorption

True or False: Water with higher salinity reduces infiltration rates due to soil dispersion effects.

• True

• False

How does temperature affect infiltration?

• Higher temperatures increase infiltration by lowering water viscosity

• Temperature has no effect on infiltration

• Lower temperatures increase infiltration

• Higher temperatures reduce infiltration

True or False: Horton’s infiltration equation assumes a linear decrease in infiltration over time.

• True

• False

Which of the following fluid properties influences infiltration the most?

• Color

• Viscosity

• Salinity

• Density

Which type of soil has the highest water-holding capacity?

• Clayey soil

• Sandy soil

• Silty soil

• Loamy soil

Which land surface condition favors higher infiltration?

• Smooth and impervious surface

• Sealed and compacted soil

• Well-vegetated surface

• Waterlogged fields
