The session of shallow geophysics calls various research topics to contribute on geophysical exploration techniques for the near surface. The shallow geophysics uses many types of methods to survey various targets. This session does not restrict any survey methods and targets of your research but restrict the target depth in the zones from 5 cm to 30 m (or from 2 in to 100 ft) below the surface of the ground. The shallow part under the ground may be the closest and unknown territory for human society, and advanced societies cannot have controlled it yet to avoid disasters caused by dynamics in the near surface. Peoples require techniques to manage levee, landslide and earth constructions and knowledge to control groundwater, liquefaction and soil pollution. The near surface faces many geotechnical, environmental and hydrogeologic problems. Major survey techniques are surface wave method, electric exploration, ground-penetrating radar and microtremor survey, but any methods can be discussed if your target is located in the shallow depths. Recently, 3D survey and machine learning have been also hot topics in this research field. Additionally, this session welcomes to discuss laboratory tests and rock physics for unconsolidated porous media in the vadose zone. Finally, we will welcome not only cutting-edge technologies but also usual works, if the knowledge and skills is useful for human living.
