What is infiltration in environmental science?
What is infiltration in environmental science?
Infiltration is the process by which water on the ground surface enters the soil. Infiltration rate in soil science is a measure of the rate at which a particular soil is able to absorb rainfall or irrigation. It is measured in inches per hour or millimeters per hour. The rate decreases as the soil becomes saturated.
What is infiltration short answer?
Infiltration is the movement of water into the ground from the surface. Percolation is movement of water past the soil going deep into the groundwater. Groundwater is the flow of water under- ground in aquifers. The water may return to the surface in springs or eventually seep into the oceans.
What is infiltration and runoff?
Infiltration occurs when surface water enters the soil. The sponge soaks up the water until it can hold no more. At this point, the soil becomes saturated, but the excess water has to go somewhere. When this happens, we get overflow in the form of runoff, which is when surface water flows over land.
How do you control infiltration?
Typically, infiltration is minimized to reduce dust, to increase thermal comfort, and to decrease energy consumption. For all buildings, infiltration can be reduced via sealing cracks in a building’s envelope, and for new construction or major renovations, by installing continuous air retarders.
What is the main purpose of infiltration?
Why it is important: Infiltration is an indicator of the soil’s ability to allow water movement into and through the soil profile. Soil temporarily stores water, making it available for root uptake, plant growth and habitat for soil organisms.
How do humans affect infiltration?
Tillage of land changes the infiltration and runoff characteristics of the land surface, which affects recharge to ground water, delivery of water and sediment to surface-water bodies, and evapotranspiration.
What is the importance of infiltration?
Infiltration is extremely important, because it determines not only the amount of water that will enter a soil, but also the entrainment of the “passenger” chemicals (nutrients and pollutants) dissolved in it.
What are the factors that affect infiltration?
Factors that affect infiltration
- Precipitation. Precipitation can impact infiltration in many ways.
- Soil characteristics. The porosity of soils is critical in determine the infiltration capacity.
- Soil moisture content.
- Organic materials in soils.
- Land cover.
- Slope.
- General hydrologic budget.
- Richards’ equation (1931)
What are the 7 factors that affect infiltration?
Factors Affecting Infiltration:
- (i) Soil Texture and Structure:
- (ii) Conditions at Soil Surface:
- (iii) Soil-Moisture Content:
- (iv) Type of Vegetative Cover:
- (v) Soil Temperature:
- (vi) Human Activities on Soil Surface:

What is infiltration and why is it important?
Why it is important: Infiltration is an indicator of the soil’s ability to allow water movement into and through the soil profile. Soil temporarily stores water, making it available for root uptake, plant growth and habitat for soil organisms.
When does infiltration happen?
Infiltration occurs when warm produce is placed into cold water. The cold water causes air pockets within the produce to contract, creating a pressure differential that pulls water into the produce.
What is infiltration water cycle?
What is the Water Cycle? Infiltration is the process by which precipitation or water soaks into subsurface soils and moves into rocks through cracks and pore spaces. As we mentioned before, the bulk of rainwater and melted snow end up infiltrated.
What is infiltration in biology?
Infiltration is the diffusion or accumulation (in a tissue or cells) of foreign substances or in amounts in excess of the normal. The material collected in those tissues or cells is called infiltrate.
