NDVI (normalized difference vegetation index) and PRI (photochemical reflectance index)—The researcher’s complete guide
Get an in-depth look at the scientific theory, measurement methods, and application of NDVI and PRI.
If you want to predict how water will move within your soil system, you need to understand hydraulic conductivity because it governs water flow. Soil infiltration rates impact irrigation, drainage, and how well water flows to crop roots. Infiltration measurements are used to predict erosion and determine soil health. And, in urban settings, stormwater systems and landfills need soil infiltration measurements to maximize or minimize water movement in soil. If you’re working in these situations, it’s critical to understand how to measure infiltration correctly, or you’ll risk inaccurate calculations that could lead to wrong decisions. These six short videos teach you everything you need to know about infiltration testing and measuring saturated and unsaturated hydraulic conductivity in soils.
In this 30-minute webinar, world-renowned soil physicist, Dr. Gaylon S. Campbell, teaches the basics of soil infiltration and how to measure it correctly.
Drs. Andrea Welker and Kristin Sample-Lord, researchers at Villanova University, are changing the way infiltration measurements are captured while keeping the standards of measurement high. They ran many infiltration tests with three types of infiltrometers with a variety of sizes and soil types. In this 30-minute webinar, they discuss what they found to be the acceptable statistical mean for a single rain garden. Plus, they reveal the pros and cons of each infiltrometer type and which ones were the most practical to use.
In this 30-minute webinar, Leo Rivera explains common mistakes to avoid and best practices that will save you time, increase your accuracy, and prevent problems that could reduce the quality of your data.

In this 20-minute webinar, METER research scientist Leo Rivera discusses how to choose the right hydraulic conductivity instrument for your application.
Macropore models that include characterization of the geometry of the macropores tend to be complicated and require more parameters than can be determined from a reasonable set of independent measurements. World-renowned scientist, Dr. John Norman, shares the M&M model approach, which is a relatively simple macropore model only requiring nine parameters.
