Hydrology And Rainfall Apparatus
Product Code : LSK-FM-10469
Hydrology And Rainfall Apparatus (SKU LSK-FM-10469) is a tilting catchment tank with overhead spray nozzles that simulate rainfall, so students can study runoff, hydrographs, groundwater levels and flow to wells. It is aimed at hydrology and water-resources practicals in civil and agricultural engineering. Science Lab Supplies manufactures the apparatus in India at its Plot 448 unit in the HSIIDC Industrial Area, Saha, Ambala, and supplies universities, tender contractors and distributors without intermediaries.
Specifications
A sturdy metal frame holds a large rectangular stainless-steel catchment tank above a reservoir tank. A pump feeds both the spray-nozzle frame and the tank ends, a flow meter records total flow, and a jacking mechanism sets the catchment slope. Twenty slotted tappings along the centre line report the water table to a piezometer bank.

Applications and Experiments for the Hydrology and Rainfall Apparatus
Students apply controlled rainfall to a sloping granular catchment and measure the outflow over time to build hydrographs, then use the tappings and wells to study groundwater. These are standard experiments in B.Tech/B.E. civil engineering hydrology and water-resources labs and agricultural engineering courses.
- Rainfall–runoff hydrographs for different intensities and catchment slopes.
- Changing hydrograph lag time, or simulating a moving storm, by switching half the nozzles.
- Water-table profiles and drawdown around one or two pumping wells.
- Recharge and drainage of the catchment through the porous end compartments.
Standard Scope of Supply
The apparatus comes as the frame with catchment and reservoir tanks, pump, spray-nozzle frame with selector valve, flow meter, jacking mechanism, 20 tappings with piezometer bank, two wells, porous-port end compartments and the calibrated rectangular weir. The granular medium that fills the catchment is available separately.
Packing, MOQ and Lead Time
You may request a price for one apparatus or for a full water-resources laboratory; the reply states the packing, delivery time and price for exactly what you list. The granular medium and related engineering lab equipment in India can be included in the same quotation.
Science Lab Supplies has an Importer-Exporter Code and is able to ship to buyers in Peru, Egypt, Iraq, Nigeria, Kenya and Ghana. Start an enquiry on the contact page, gather products in the enquiry cart, or see how tenders are handled on the lab tender page.
Frequently Asked Questions
Is the sand or gravel for the catchment included?
No. The granular medium that forms the permeable catchment is available separately, so it can be added to the quotation if required.
How is outflow from the catchment measured?
A calibrated rectangular weir under the catchment measures flow from the wells or the tank, while a flow meter records the overall flow delivered by the pump.
Can the rainfall pattern be changed?
Yes. Students vary the flow to the nozzles, and a valve selects all or half of the nozzles to alter the hydrograph lag time or simulate a storm moving across the catchment.
Is Science Lab Supplies the manufacturer or a trader?
It is the manufacturer. The frame, tanks and nozzle system are fabricated in its Saha, Ambala plant in India, and prices are quoted from there.
