SINGLE RING INFILTROMETER
Objective:
To measure the rate of infiltration or the rate at which water enters in soil.
Apparatus used:
Single Ring Infiltrometer(diameter of 15cm and 30cm ring), Hammer, Water Level Indicator, Stopwatch, etc.

Description
Infiltrometer: is an experimental device to obtain the volume of water entering into soil at various time intervals.
Select the diameter of ring for the trial.

Place ring and hammer the ring of the infiltrometer into the soil using driving plate.
Place the water level indicator inside the ring.
Fill the water into the ring upto the marked level.

Inference:The initial infiltration rate is higher, however as the soil pores get filled with water infiltration rate gradually decreases and reaches steady state.
