SF4001 Environmental Geotechnology Syllabus:
SF4001 Environmental Geotechnology Syllabus – Anna University PG Syllabus Regulation 2021
OBJECTIVES:
The student acquires the knowledge on the Geotechnical engineering problems associated with soil contamination, safe disposal of waste and remediate the contaminated soils by different techniques thereby protecting environment.
UNIT I SOIL – WASTE INTERACTION
Role of Geoenvironmental Engineering – sources, generation and classification of wastes – causes and consequences of soil pollution – case studies in soil failure – factors influencing soil-pollutant interaction – modification of index, chemical and engineering properties – physical and physiochemical mechanisms- Environmental laws and regulations
UNIT II CONTAMINANT TRANSPORT AND SITE CHARACTERISATION
Transport of contaminant in subsurface – advection, diffusion, dispersion – chemical process – biological process, sorption, desorption, precipitation, dissolution, oxidation, complexation, ion exchange, volatization, biodegradation – characterization of contaminated sites – soil and rock data – hydrological and chemical data – analysis and evaluation – risk assessment – case studies.
UNIT III WASTE CONTAINMENT AND REMEDIATION OF CONTAMINATED SITES
Insitu containment – vertical and horizontal barrier – surface cover – ground water pumping system on subsurface drain – soil remediation – soil vapour extraction, soil waste stabilization, solidification of soils, electrokinetic remediation, soil heating, vitrification, bio remediation, phyto remediation – ground water remediation – pump and treat ,Insitu flushing, permeable reacting barrier, Insitu air sparging – case studies.
UNIT IV LANDFILLS AND SURFACE IMPOUNDMENTS
Source and characteristics of waste – site selection for landfills – components of landfills – liner system – soil, geomembrane, geosynthetic clay, geocomposite liner system – leachate collection – final cover design – monitoring landfill.
UNIT V STABILISATION OF WASTE
Evaluation of waste materials – flyash, municipal sludge, plastics, scrap tire, blast furnace slag, construction waste, wood waste and their physical, chemical and biological characteristics – potential reuse – utilization of waste and soil stabilization – case studies.
OUTCOMES:
On completion of the course, the student is expected to be able to;
CO1 Understand the various causes and consequences of waste interaction with soil and their modification.
CO2 Understand the various mechanism of transport of contaminants into the subsurface and characterization of contaminated sites and their risk analysis.
CO3 Understand on how to decontaminate the site so as to reuse the site for human settlement
CO4 Understand how to safely dispose the waste through different containment process.
CO5 Expose on how to convert the waste into a resource material through soil waste stabilization techniques with or without chemical stabilization.
