A research team led by Han Jong Su, a section head at the Faculty of Earth Science and Technology, has developed an analysis method of geological structures of irrigation canals and waterway tunnels by magnetic field survey.

Finding out about geological basement is of primary importance for qualitative guarantee of watercourse construction and its safe operation.

Magnetic survey is one of the cheap but speedy and accurate methods.

Magnetic survey based on magnetic susceptibility is considered effective for detecting horizontal and vertical position of boundaries between geological bodies in building a shallow subsurface construction. This method has already contributed to the building of a 100 km watercourse by analyzing the depth and outline of the weathered layers, geological structure and karst.
