“…Geophysical methods such as GPR may be relevant for the estimation of the spatial variations of sub-surface features including the depth to saprolite upper boundary (e.g. Dominic et al, 1995;Lapen et al, 1996). At the same study site Chaplot et al (2001b) showed the interesting potential of the Radio Magneto Tellurique (RMT) in predicting the spatial variations of the depth to the saprolite upper boundary.…”

“…Common offset profile is the most common technique in GPR acquisition, mainly for large field, as in the case of agricultural applications. Furthermore, the representation of GPR data, by radar traces placed downward on sections, resembles well a soil cross section where the depth scale is expressed as a transformation of a two‐way travel time (Dominic et al ; Kruse et al ; Grasmueck, Weger and Horstmeyer ; Mount, Comas and Cunningham ). To estimate the electromagnetic waves’ propagation velocity within the different soil layers presented in the study area, the numerous hyperbolic diffraction curves presented in the radargrams were used.…”

Petrosalic horizon (cemented by soluble salts) is identified as a root‐restricting layer in the arid and semi‐arid regions. The knowledge of the variability of cemented layers within the soil profiles provides valuable information to decision‐makers for agricultural and/or engineering activities. This study was conducted to evaluate the potential of ground‐penetrating radar in detecting petrosalic horizon within the soil pedon in an arid area (Kerman Province, southeastern Iran). The measurements were performed using an impulse ground‐penetrating radar system with a centre frequency of 250 MHz along ten parallel transects of 100‐m length and 10‐m distance between two consecutive transects at two sites. The results of the soil stratigraphy indicated the presence of petrosalic horizons at 12‐ to 36‐cm depth. The ground‐penetrating radar images showed patterns corresponding to these soil horizons. The interpreted radargrams were quite consistent with the findings of the soil pedons. It is, therefore, suggested that ground‐penetrating radar could be employed to detect the boundaries between different soil horizons in the arid areas with various degrees of conductivity. This, in turn, helps differentiate soil‐mapping units and improve the reliability and accuracy of digital soil maps. The results confirmed that ground‐penetrating radar could be used as a rapid, efficient and non‐destructive tool providing highresolution and continuous visualisation of the soil horizons to detect the presence and depth of petro‐salic horizons. Such information could be crucial in making decisions in agricultural practices (e.g., creating gardens) and engineering activities (e.g., constructing roads and buildings).

“…GPR record interpretation was based on correlation with cores, trenches, and open pits at or near profile lines. The interpretation of profile records was aided by criteria detailed in other GPR studies (Jol and Smith, 1991;Smith and Jol, 1992;Dominic et al, 1995;van Heteren et al, 1998). Terminology used to describe reflection configurations is that of van Heteren et al (1998).…”

Detailed study of the Sanford-Kennebunk sand plain using sediment analysis of 125 samples from 20 locations and 37 km of ground-penetrating radar (GPR) indicates that much of the feature can trace its origins to regressive-phase deltaic deposition during the late Pleistocene.The Sanford-Kennebunk sand plain is an ϳ125 km 2 elongate, west-east-trending landform overlying a large, deep bedrock trough. With the exception of the eastern coastal margin, the entire sand plain is bordered by bedrock uplands.The plain is composed of coarsening-upward sand and minor gravel. Sediment sorting ranges from poor to moderate in the western plain, to moderate to good in the eastern sector. Grain size generally decreases from west to east.Extensive ground-penetrating radar coverage shows that many areas display packages of clinoforms, the thicknesses of which range from shallow, Ͻ1 m thick, channel fill-type deposits to the more common 5-14-m-thick, rhythmic, inclined (4Њ-15Њ average dip) beds. Dip directions generally radiate outward from the west-central plain, and farther eastward, from the south-central plain. These GPR records in conjunction with the sediment analyses strongly suggest a deltaic origin for the orderly dipping beds of the sand plain.A model for development and evolution of the sand plain encompasses deglaciation, associated marine incursion, and subsequent regression. As ice retreated from the area and isostatic recovery led to marine regression, sediments from the glacier's margin were transported in energetic meltwater channels to be deposited in a bedrock-enclosed, marine bathymetric low, forming the Sanford-Kennebunk sand plain.
