Infiltration of water is the ability to observe and analyze the movement of water in different types of soil and rock formations, and to understand how water percolates through these materials. It involves the use of sophisticated tools and techniques to measure flow rates, water retention, and other important parameters. Specialists in infiltration can help farmers and land managers determine the best ways to irrigate crops or manage water resources, and can also assist in the design and construction of water storage and filtration systems. The skill requires a deep understanding of geology, hydrology, and engineering principles, and is essential for ensuring the sustainable use of water resources in many different settings.
