GEOPHYSICAL IMAGING OF KARST FEATURES IN MISSOURI By JEREMIAH CHUKWUNONSO OBI A DISSERTATION Presented to the Faculty of the Graduate School of the MISSOURI UNIVERSITY OF SCIENCE AND TECHNOLOGY In Partial Fulfilment of the Requirements for the Degree DOCTOR OF PHILOSOPHY In GEOLOGICAL ENGINEERING 2016 Approved by Neil L. Anderson, Advisor J. David Rogers Kelly Liu Evgeniy V. Torgashov Mao Chen Ge © 2016 Jeremiah Chukwunonso Obi All Rights Reserved iii ABSTRACT Automated electrical resistivity tomography (ERT) supported with multichannel analysis of surface waves (MASW) and boring data were used to map karst related features in Missouri in order to understand karst processes better in Missouri. Previous works on karst in Missouri were mostly surficial mapping of bedrock outcrops and joints, which are not enough to define the internal structure of karst system, since most critical processes in karst occur underground.
