Geostatistical Integration Analysis of Geophysical Survey and Borehole Data Applying Digital Map

Borehole Geophysical Logging in Unconsolidated Sediments

Over the last two decades, several advances have been made in the development and application of slim-hole geophysical sondes for use in groundwater, engineering, and environmental applications. This equipment is commonly used to provide qualitative (but detailed) estimates of grain size, sediment type, porosity, density, pore-water salinity, as well as bulk and shear moduli, to supplement geol...

Geostatistical Analysis of Spatial Data

First, geostatistics provides descriptive tools such as semivariograms to characterize the spatial pattern of continuous and categorical soil attributes. Various interpolation (kriging) techniques capitalize on the spatial correlation between observations to predict attribute values at unsampled locations using information related to one or several attributes. An important contribution of geost...

Identifying Unsaturated Hydraulic Parameters Using an Integrated Data Fusion Approach on Cross-Borehole Geophysical Data

238 C geophysical methods are increasingly used to estimate hydrogeologic properties of the unsaturated zone. Th ese methods provide high-resolution in situ information for large support volumes of the subsurface with minimal intrusion and thereby have obvious advantages over other more traditional methods such as neutron probe and time domain refl ectrometry. In particular, cross-borehole elec...
