Non-destructive techniques for mapping agricultural subsurface drainage systems

PhD defence, Tuesday 27 April 2021, Triven Koganti

Triven Koganti

During his PhD studies, Triven Koganti investigated a variety of proximal (Ground penetrating radar, Magnetic gradiometer) and remote (Unmanned aerial vehicle imagery captured using different cameras) sensing technologies to discern their potential in mapping agricultural subsurface drainage systems (popularly known as “tile drains”). Triven Koganti conducted research both in Denmark and the Midwestern United States on a wide range of soil types as the drainage practices, especially the drainage pipe diameters that are typically used differ between Europe and the U.S.A.

The new research findings contribute to understanding the efficacy of different non-destructive sensing technology in mapping the agricultural drainage pipes. Subsequently, Triven Koganti provided guidelines based on a decision support flowchart diagram to assist the farmers/site managers/land improvement contractors on optimal timing to employ the sensory technology to achieve maximal success in subsurface drainage mapping.

The PhD study was completed at Department of Agroecology, Faculty of Technical Sciences, Aarhus University.

This summary was prepared by the PhD student.
