Delineating Lake Bottom Structure by Resistivity Image Profiling on Water Surface


Mapping water-bottom features involves in the fields of environmental geophysics and engineering structural studies. Standard direct current (DC) resistivity sounding is widely used to map subsurface structures on land, but it is seldom used to map underwater structures, because the deployment of underwater electrodes along the water-bottom is expensive and cumbersome. Therefore, a cost-effective and non-destructive survey technique is required to map underwater structures.
