Movement of water into soil is called infiltration, and the downward movement of water within the soil is called percolation, permeability or hydraulic conductivity. Pore space. Spaces in soil, between the mineral and organic matter, that are filled with water or air.

What are the 3 types of water movement in soil?
Generally three types of water movement within the soil are recognized –saturated flow, unsaturated flow and water vapour flow (Fig. 23.1). Water in the liquid phase moves through the water filled pores within the soil (saturated condition) under the influence of gravitational force.

What is the rate at which water moves through the soil called?
Infiltration (the rate at which water enters a soil) and percolation (the rate at which water moves through a soil) are key factors in determining the value of a soil as a crop soil. These two factors influence the formation of natural wildlife habitats, and the nature and speed of flooding in a given area.

What is percolation vs infiltration?
Infiltration and percolation are two related but different processes describing the movement of water through soil. Infiltration is defined as the downward entry of water into the soil or rock surface and percolation is the flow of water through soil and porous or fractured rock.

What are the soil water movements?
Soil water movement is classified into saturated flow, unsaturated flow, and vapor flow. Saturated flow occurs at tensions of 0 to -0.3 bar, between saturation and field capacity. The rate of flow depends on hydraulic conductivity, which is controlled by pore size.

What are the different kinds of water movement?
The horizontal and vertical motions are common in ocean water bodies. The horizontal motion refers to the ocean currents and waves. The vertical motion refers to tides. Ocean currents are the continuous flow of huge amount of water in a definite direction while the waves are the horizontal motion of water.

What is the difference between percolation and infiltration and permeability?
Downward entry of water into the soil or rock surface. Initial surface infiltration occurs at a faster rate than percolation rate. Percolation occurs at a much slower speed.

Which is faster infiltration or percolation?
PERMEABILITY= How WELL water can flow through soil particles. Example: Clay is NOT as permeable to water as GRAVEL is. PERCOLATION= The RATE at which water can travel through the soil particles.

What is the difference between percolation and permeability?
Water starts as precipitation and then it seeps into the soil similar to a sponge soaking up water. Infiltration is the moving of surface water into the soil.
