National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Use of Radar Methods to Determine Moisture Content in the Vadose Zone.

DE2004833525

Publication Date	2000
Personal Author	Knight, R.
Page Count	4
Abstract	The objective of our three-year research project is to determine the optimal way to use radar methods to obtain information about moisture content in the vadose zone. In our research we will focus on two specific aspects of the link between radar images and moisture content. The first aspect or question we address is: Can we use a measure of the dielectric constant of a volume of the subsurface to determine the moisture content of that volume. The second question we address is involved specifically with the issue of spatial heterogeneity. Rather than using radar data to get estimates of moisture content at specific locations, can we use the radar data to directly obtain information about the way in which the level of moisture content varies spatially.
