About Rainfall Hydrograph

Rainfall Hydrograph:

This apparatus sets out to demonstrate, on a small-scale, some of the physical processes found in hydrology. These fall into two related categories: the relationship between rainfall and runoff from catchment areas of variable permeability and the abstraction of ground water by wells, with or without surface recharge from rainfall. Thus it is concerned with that part of the hydrological cycle bounded by the arrival of 'net rainfall' on the ground surface and the catchment runoff by surface streams.

Specification of Rainfall Hydrograph :

A unit designed to obtain catchment rainfall and runoff values as functions of time.
Comprising a bench- or floor-standing tank with two overhead square pattern spray nozzles supplying water via a flow control valve, flow meter and solenoid valve.
A motor-driven traversing vessel with 17 compartments is moved by timer beneath the outlet at a preselected rate to collect the runoff and provide an immediate display of the hydrograph.
The tank is 1.2m long x 0.8m wide x 0.2m deep.
The flow range is 0.4-4.4 l/min.

Demonstration Capability :

Storm hydrograph from single or multiple storms.
Storm hydrograph from a previously saturated catchment.
Storm runoff from an impermeable catchment.
Effect of a moving storm on flood hydrograph.
Effect of reservoir storage on flood hydrograph.
Effect of land drains on flood hydrograph.

Continuous and Accurate Rainfall Tracking

The RH-01 Hydrograph measures precipitation every hour, with data clearly charted over a 24-hour period. Its analog recording and 1 mm accuracy ensure dependable readings crucial for flood monitoring and water management projects.

All-Weather Durable Design

Engineered for resilience, the RH-01 is built with rustproof MS sheet metal and weatherproof characteristics. It consistently performs outdoors in temperatures from 0C to 50C, making it reliable for year-round operation in diverse Indian climates.

Effortless Operation and Maintenance

The spring-driven mechanism requires no electricity, operating continuously without external power. Chart replacement and occasional cleaning are simple, guaranteeing minimal downtime and easy maintenance, making it ideal for remote field deployment.

FAQs of Rainfall Hydrograph:

Q: How does the Rainfall Hydrograph record rainfall data?

A: The RH-01 hydrograph collects rainwater through its 200 cm collector funnel and measures rainfall using a mechanical float system. As rain accumulates, the water level moves a pen on the chart paper, creating a visual hydrograph of rainfall intensity over a 24-hour period. The spring-driven clock mechanism ensures precise chart rotation for accurate data recording.

Q: What steps are involved in using the RH-01 Hydrograph?

A: To use the RH-01, set up the instrument on a stable, level surface outdoors by mounting it on a bench or portable stand. Place the specialized hydrograph chart paper on the drum, wind the clock mechanism, and ensure the collector funnel is clean. The device then autonomously records rainfall data for up to 24 hours, after which you can remove and interpret the chart manually.

Q: When should I perform maintenance on this hydrograph?

A: Routine maintenance for the RH-01 is minimal and typically involves replacing the chart paper after every 24-hour cycle or after significant rainfall events. Its recommended to clean the rain collector funnel and inspect the clock mechanism periodically to ensure accurate readings and smooth operation.

Q: Where should the RH-01 hydrograph be installed for best results?

A: For optimal accuracy, install the RH-01 hydrograph in an open outdoor area away from overhanging trees, buildings, or obstructions that might shield rainfall. The weatherproof and rustproof construction allows for reliable operation across varied environments and climates.

Q: What benefits does the analog paper chart display offer?

A: The analog chart provides a clear, continuous visual record of rainfall patterns, allowing easy manual interpretation and immediate access to critical data without the need for electronic devices. This is especially beneficial in remote locations or field studies where digital tools may not be practical.

Q: How is the RH-01 powered, and is external electricity required?

A: The RH-01 operates solely on a spring-driven clock mechanism, requiring no external power source. This manual operation ensures uninterrupted rainfall data collection even in off-grid or power-restricted environments.
