Hydrological Connectivity of Soil Pipes Determined by Ground-penetrating Radar Tracer Detection
Soil pipes are common and important features of many catchments, particularly in semi-arid and humid areas, and can contribute a large proportion of runoff to river systems. They may also significantly influence catchment sediment and solute yield. However, there are often problems in finding and defining soil pipe networks which are located deep below the surface. Ground-penetrating radar (GPR...
متن کاملGround Penetrating Radar Migration with Uncertain Parameters
In this paper the focusing principle of Kirchoff migration is described. This allows the introduction of optical focusing techniques that can be used to focus migration. Three focus measures are described that are useful for optimising migration. Simple optimisation routines are implemented that model uncertainties in the migration parameters. The focus measures are then used as cost functions ...
متن کاملMeasuring Soil Water Content with Ground Penetrating Radar: A Review
termines the diurnal evolution of the atmospheric boundary layer (Callies et al., 1998). Currently, there is a need We present a comprehensive review of methods to measure soil to establish and quantify the contribution of soil water water content with ground penetrating radar (GPR). We distinguish content–regulated land–atmosphere coupling to regional four methodologies: soil water content det...
متن کاملGround-Penetrating Radar
Ground-penetrating radar (GPR) has recently gained a wide acceptance in the archaeological community as a method that can quickly and accurately locate buried archaeological features, artifacts, and important cultural strata in the near-surface. The GPR method has been especially effective in certain sediments and soils between about 20 cm and 5 m below the ground surface, where the targets to ...
متن کاملGround - Penetrating Radar ( Paper
GPR senses electrical inhomogeneities, with these manifested, for example, by the electrical contrast of a metal mine in the presence of a far-less-conducting soil background. Of much more difficulty, GPR senses the electrical inhomogeneity caused by a dielectric (plastic) landmine in the presence of soil. Often this contrast is very weak, implying that the landmine GPR signal is very small. Th...
