The fastest way to get Field Soil Hydraulic Data in 3D, the data of natural flow patterns 27 Too often measurements of hydraulic properties have been confined to vertical parameters only, take hours of time and are not related in many ways to the reality of 3 dimensional flow in nature. The Guelph has been a break through in the science of soil permeability allowing for multiple depth, multiple head heights all in the same bore hole. Measurements are based on both vertical (gravity) and lateral (capillary) flow from a point source of known head height forming saturated flow patterns as would be the case in nature. The ideal instrument obtaining in-situ hydraulic conductivity data, when designing a Landfill Site for Monitoring Hazardous Waste Disposal or Hydrological Investigations in Drainage or Soil Erosion Studies. The model 2800K1 Guelph Permeameter is an easy to use instrument for quickly and accurately measuring in-situ hydraulic conductivity, generally less than 20 minutes. These quick measurements, at various depths will provide efficiency of irrigation and drainage, optimizing the availability of water for plants, improving the yield of crops and minimizing erosion. This instrument with accessory items 2805D Pressure Infiltrometer attachments can also be used to check clay liners in water and solution holding farms. Constructed of tough polycarbonate and acrylic, it has no items to corrode or get plugged over years of use. The stand included with the unit allows for easy setup and take down in a matter of minutes. The valve at the base of the reservoirs allows you to choose an inner (for very low flow soils) and larger outer reservoir capacity (for moderate and high flow soils). Measurement with the Guelph Permeameter may be made from 0 to 20-ft (610-cm) depth. Meeting the requirements of ASTM – 5126, our permeameters and infiltrometers are rugged field ready kits that are lightweight and durable, and can be operated by one person.
