Hydrology and Rainfall Apparatus Manufacturer,Supplier and Exporter in India
Product Code : EL-FMP-11314
Quick Answer: The Hydrology and Rainfall Apparatus has a catchment area with adjustable slope beneath a frame of spray nozzles that simulate rainfall. A row of 20 tappings along its centre line feeds a bank of piezometer tubes to show the water table profile.

Key Features
- Jacking mechanism adjusts the angle of the catchment area
- Overhead spray nozzles simulate rainfall; a valve selects all or half the nozzles to vary hydrograph lag time or simulate a moving storm
- Row of 20 tappings along the catchment centre line, with slotted ends that keep the permeable media out, connected to piezometer tubes at the front
- Port holes drain water from the catchment or supply it from the end compartments
- Pump feeds reservoir water to the nozzles and catchment ends with variable flow; a flow meter measures the overall flow
- Calibrated rectangular weir under the catchment measures flow from the wells or the tank

About This Product
The apparatus brings rainfall-runoff and groundwater work into one unit. Students produce hydrographs for different storms and slopes, follow how the water table responds, and study flow to and from the wells and end compartments.
Frequently Asked Questions
How is a moving storm simulated on the Hydrology and Rainfall Apparatus?
A valve selects all or half of the spray nozzles. Switching between them lets students vary the lag time on a hydrograph or simulate a moving storm.
How is the water table measured?
A row of 20 tappings along the centre line of the catchment area connects to a bank of piezometer tubes at the front, giving the water table profile.
