Differbetween
The terms infiltration and percolation are often used interchangeably, however, percolation specifically refers to the movement of water within the soil, while infiltration refers to water entering the soil surface. The infiltration rate is the amount of water that enters the soil in a specified time period.

What is the difference between infiltration rate and percolation rate?
Thus, the Percolation process represents the flow of water from unsaturated zone to the saturated zone.

| Infiltration is the process by which water on the ground surface enters the soil. | Percolation is concerned with the movement and filtering of fluids through porous materials. |
What is the difference between percolation and runoff?
Runoff is the part of precipitation, snow melt or irrigation water that appears uncontrolled in rivers, streams, drains and sewers. It includes both surface and subsurface flows. ... A percolation test measures the rate at which water seeps into soil. The rate of percolation is determined by how porous a surface is.
What is infiltration rate?
Infiltration rates are a measure of how fast water enters the soil and are typically expressed in inches per hour. For initial in-field assessments, however, it is more practical to express infiltration time in the number of minutes it takes soil to absorb each inch of water applied to the soil surface.
What's a infiltration?
Infiltration is the process by which water on the ground surface enters the soil. Infiltration is governed by two forces, gravity, and capillary action. ... Infiltration rate in soil science is a measure of the rate at which a particular soil is able to absorb rainfall or irrigation.
What happens after percolation?
Water infiltrates the soil by moving through the surface. Percolation is the movement of water through the soil itself. Finally, as the water percolates into the deeper layers of the soil, it reaches ground water, which is water below the surface.
How does infiltration happen?
Infiltration occurs when surface water enters the soil. This process is similar to pouring water onto a sponge. 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.
Does percolation clean water?
Surface runoff is an important part of the water cycle because, through surface runoff, much of the water returns again to the oceans, where a great deal of evaporation occurs. Percolation is an important process where rain water soaks into (infiltrates) the ground, into the soil and underlying rock layers.
How do you calculate infiltration rate?
The infiltration volume is obtained by subtracting runoff volume from rainfall volume. The average infiltration rate is obtained by dividing infiltration volume by rainfall duration.
What is infiltration short answer?
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 factors affect infiltration rate?
The main factors that influence the infiltration are:
- the soil type (texture, structure, hydrodynamic characteristics). ...
- the soil coverage. ...
- the topography and morphology of slopes;
- the flow supply (rain intensity, irrigation flow);
- the initial condition of soil humidity.
