Sediment Transport Demonstration Channel Manufacturer,Supplier and Exporter in India

Product Code : SCL-CELE-14182

Overview

The Sedimentation Demonstration Channel provides a compact, self-contained, and highly visual system for studying open channel flow, sediment transport, and bedform development under controlled laboratory conditions.

Designed to clearly demonstrate the sequence of bedforms that arise as flow velocity and slope increase, this apparatus allows users to explore both fixed bed and mobile sand bed flow phenomena. It replicates, at a smaller scale, many experiments typically requiring large, technician-supported flumes—making it an ideal teaching tool for courses in hydraulics, sedimentology, fluvial geomorphology, and civil engineering.

The channel’s transparent acrylic construction allows complete visibility of sediment motion and flow structures, while the inclinable design and recirculating pump system enable flexible and repeatable experimentation.

A detailed Operation & Maintenance Manual is supplied with the trainer.

Key Features

• Transparent inclinable flow channel for direct observation of flow and sediment transport.
• Demonstrates both fixed bed flow (smooth and gravel beds) and mobile sand bed flow.
• Shows the complete sequence of bedforms — from ripples and dunes to anti-dunes and chutes.
• Self-contained, portable unit — ideal for classroom or laboratory use.
• Adjustable slope (0–10%) for varying flow conditions.
• Recirculating pump system with three selectable discharge rates (0.2–0.6 L/s).
• Demonstrates key hydraulic phenomena such as hydraulic jumps, turbulence, flow resistance, and local scour.
• Supplied with model bridge pier and undershot weir for scour and obstruction studies.
• Low maintenance, cost-effective alternative to large-scale sediment transport flumes.

Technical Specifications

Experimental Capabilities

A. Fixed Bed Flow

• Observation of tranquil (subcritical) and rapid (supercritical) flow.
• Demonstration of hydraulic jumps, turbulence, and wave propagation.
• Flow measurement using sharp-crested weirs.
• Application of Reynolds’, Froude, and Bernoulli’s equations for open channel flow analysis.

B. Flow Over Mobile Sand Bed

• Visualization of bedform development with increasing flow intensity:
• Plane bed (no motion)
• Ripples → Dunes → Washed-out dunes
• Plane bed (with motion) → Standing waves → Antidunes → Breaking antidunes → Chutes and pools
• Study of sediment initiation and transport mechanisms (rolling, sliding, saltation, suspension).
• Examination of sediment deposition patterns and cross-bedding structures.

C. Local Scour and Flow Structures

• Study of scour formation around obstructions (bridge piers, sills, revetments).
• Visualization of turbulent structures using dye injection (not included).
• Observation of vortex formation and flow separation.

D. Bedform Hysteresis

• Simulation of a flood hydrograph by varying discharge rate.
• Observation of stage-discharge hysteresis — different flow depths for the same discharge on rising and falling limbs.

E. Computational and Analytical Studies (Optional)

• Calculation of flow resistance coefficients (Manning, Chezy, Darcy-Weisbach).
• Bedform prediction using:
• Hjulström diagram (velocity)
• Shields diagram (critical shear stress)
• Simons & Richardson, Bogardi, and Leeder charts (stream power, boundary shear).
• Flow over fixed gravel bed — evaluation of resistance equations (Bray, Hey, Bathurst, etc.).

Educational Objectives

• Understand the interaction between flow energy and sediment transport.
• Identify hydraulic regimes and associated bedforms.
• Measure and analyze flow resistance, sediment load, and erosion rates.
• Relate laboratory observations to natural river and coastal environments.
• Study the formation and preservation of depositional structures in sedimentary geology.
