Product Code : SCL-CELE-14155
Description
The Rainfall Simulator Apparatus is a self-contained
floor-standing system designed for laboratory studies in hydrology, soil
erosion, infiltration, and surface runoff analysis. It provides a controlled
and repeatable rainfall environment, eliminating the unpredictable
variability of natural rain.
The apparatus enables users to perform
detailed investigations into soil erosion, infiltration rates, surface
runoff, and vegetation effects under simulated rainfall conditions. Water
from a storage tank is circulated via a centrifugal pump through flow
control valves and meters to stainless steel spray nozzles mounted on an
adjustable gantry.
A stainless-steel catchment tank with
transparent sight glass allows visual observation of soil behavior under
rainfall. The system supports both manual and computer-controlled (DAQ)
operation for real-time monitoring and data collection.
