| Preamble |
|---|
| The course focuses on the strength of soils and the stability of structures built on soils and rocks. It considers the stresses generated in soils both due to groundwater flow and external loading.
These processes are considered in the context of a changing climate, which affects both groundwater flow as well as processes in soils. Through simple models, we evaluate the potential of engineered responses to global climate change and possible strategies for mitigation. |
| Syllabus |
|---|
| Engineering classification of soils, soil properties and weight-volume relationships, consistency of soils, Atterberg limits, relative density of soils, stresses in soils (Total stress, pore water pressure, effective stress), stability of soils during upward and downward flow of groundwater, quicksand conditions, tests of soil permeability, Laplaces equation of continuity and groundwater flow.
Impacts of global climate change on the carbon cycle, on the Earths energy balance and on groundwater quality and availability, evaluating the carbon footprint of various fossil fuels, and exploring potential adjustments to engineered systems for climate change mitigation. |
