A free standing, self-contained apparatus for laboratory scale demonstrations of surface irrigation and related systems such as surface and sub-surface effects of surface water application.
May be used either in the laboratory or the field. It is for use in simulated soil erosion and stabilization studies, enabling investigation into the relationship between rainfall intensity and soil erosion, the nature of soil erosion potential on different soil types and the methods by which erosion may be prevented.
Primarily for the derivation of soil moisture characteristic curves for a variety of soils. The equipment helps in understanding the principle of water retentivity in terms of soil suction and the relationship between water retentivity and soil moisture.
A simple but effective laboratory demonstration of the infiltration processes which are fundamental to any form of irrigation study.
Provides a simple but effective item of equipment for the measurement of evapotranspiration by the water-balance method. Suitable for student project work as well as for demonstration purposes.
Suitable for use as a demonstration tool and for laboratory testing and research. For the laboratory investigation of field drain filter materials, it allows students to determine relative efficiencies of filter materials and select optimum filter/soil combinations.
A range of tough, durable and portable flumes and weirs for the measurement of water flow rates in open channels.
In irrigation networks, the regulation of water discharge, its distribution and disposal are paramount. In order to familiarize technicians with the mode of operation of a variety of control structures, we provide this range of demonstration units.
