Infiltration: process by which water enters the soil surface
Infiltration capacity: maximum rate at which water can enter the soil
Some Important Soil Characteristics
Darcy’s Law (1856)
Hydraulic Conductivity in Soils
Infiltration by Horton’s method
An average constant value of infiltration is called infiltration index.
Two types of infiltration indices are commonly used.-index
1. f -index
2. w –index
How to Measure Infiltration?
Disc Permeameter and Tension Infiltrometer
Intensity – Infiltration
Factors which affect infiltration
Initial soil moisture content
Quality of water
