OVERVIEW OVERVIEW IIT Bombay Slide 1 The course (engineering philosophy) deals with incorporating the influence of environmental effects (either man made or natural) on conventional geotechnical engineering practices. It is gaining significant attention of engineers, researchers and planners due to rapid and uncontrolled industrialization, which yields a huge amount of hazardous waste (contaminants). It’s a blend of geotechnical and environmental engineering and deals with studies related to safe disposal and handling of the waste, estimation of its spread and fate in the subsurface, methods to contain its spread in the subsurface and of schemes for remediation Autumn 2013 D N Singh of the contaminated land(s).
IIT Bombay Slide 2 OVERVIEW ........ OVERVIEW ........ It also encompasses safe transportation and disposal, and development of suitable strategy for proper utilization of the waste. Apart from a discussion on these issues, this course highlights the importance and relevance of revising the basic concepts of geotechnical engineering so as to deal with the concerns raised by these issues, in the most befitting manner. In addition to this, the course focuses on pointing out the role and importance of the parameters and mechanisms that govern interaction of contaminants with geomaterials (soil and rock mass), and their degradation, due to the presence of chemicals and/or radio-nuclides in undesirable concentrations and at elevated temperatures, in the long-run.

IIT Bombay Slide 3 OVERVIEW....... OVERVIEW....... However, as contaminant-geomaterial interaction is an extremely slow and complex process, which primarily depends on their physical, chemical and mineralogical properties, it is quite difficult to study this interaction under laboratory or in situ conditions. This calls for resorting to various modeling techniques such as accelerated physical modeling, using a geotechnical centrifuge, finite element/difference based numerical modelling and physico-chemico-mineralogical modeling techniques.

IIT Bombay Slide 4 OVERVIEW..... OVERVIEW..... The contents of this course are mainly based on the research findings of the instructor and his Ph.D. and Masters students who have been instrumental in developing a unique laboratory (Environmental Geotechnics Laboratory) in the Department of Civil Enginering, IIT Bombay.
