An infiltration test usually relates to provide a drainage or flood risk strategy for the site. Flood Risk assessments may require an infiltration test to bee carried out.
an Infiltration test measures the rate at which water can pass through and be asborbed by the soil, the test will mesure the speed at which the water enters the soil and is absorbed.
he speed of infiltration is measured in the amount of water absorbed per hour. This amount is in inches or in millimeters. The infiltration capacity of a soil is high at the beginning of a storm and has an exponential decay as the time elapses.
The rates of water being absorbed are measured through an instrument which is called “Infiltrometer”.
