Soil moisture is one of crucial parameters in modeling and analysis of groundwater flow. Measurement of soil water dynamics improves the understanding of processes and is vital for good groundwater flow model calibration. Determining soil moisture change during time by laboratory methods, as an integral part of practical classes, requires significa...

In this paper, the possibility of applying Kirchhoff 's scalar approximation model for determining the backscattering coefficient from rough surfaces is investigated. Surfaces of dielectric and metallic materials, which have low roughness are considered. Based on the roughness parameters and electrical properties of these materials, the backscatter...
