Digital inventory and interactive map of subsurface data, including geotechnical boring logs, test pit logs, and water well records, with lithology information and links to original source documentation.
Geotechnical Mapping - (Intro to Geotechnical Science) - Fiveable
Geotechnical mapping helps identify variations in soil properties that can influence slope behavior and failure risk. The mapping process often includes field investigations, such as drilling boreholes and conducting in-situ tests to collect data.
Engineering Geological Maps - SpringerLink
Jan 1, 2018 · Engineering geological maps now cover a much broader range including geohazard maps, maps for planning and development in urban areas, environmental geological maps covering issues such as pollution and contamination, and the siting of waste disposal sites, as well as the more traditional geotechnical maps.
CMW | Geotechnical Mapping - CMW Geosciences
The purpose of a geotechnical investigation is to understand the nature of the ground conditions at a project development site that are relevant to the proposed scheme. One of the primary and fundamental components of this investigation process is geological mapping.
