Syllabus
Natural origins of soils, Biological processes in soils, The geologic origin of a soil, its depositional mode and environment, thixotropic processes.
Use of biological process for changes in physical properties (density, gradation, porosity, saturation), conduction properties (hydraulic, electrical, thermal), mechanical properties (stiffness, dilation, compressibility, swell/shrink, cohesion, cementation, friction angle, erodibility, and soil-water characteristic curve), and chemical composition (buffering, reactivity, cation exchange capacity) of soils.
Development of a biomediated soil improvement technique bioaugmentation (where the required microbes are injected into the soil) and biostimulation (where natural microbes are stimulated) Biogeochemical and geotechnical models, management of treatment of by-products
Durability and longevity/reversibility of the process, and education of engineers and researchers.
