What do subway systems, a working water faucet, rehabilitated mining landscapes, and the Gardiner Expressway have in common? All of them depend on civil engineers for their construction and functioning. Make a lasting contribution to society by understanding and shaping the built environment sustainably. In the face of rapid global population growth, undeniable shifts in climactic patterns and the consequences of these changes, research and teaching in the Civil Engineering graduate program focus on sustainable development through the use of recycled and renewable construction materials, landscape rehabilitation and the use of marginal-quality land such as closed municipal landfills and degrading permafrost. The department also emphasizes the design of civil infrastructure capable of withstanding extreme weather conditions, as well as the replacement or appropriate retrofitting of existing structures. Given the breadth of knowledge and skills provided in a Civil Engineering program, graduates will find fulfilling and challenging professional opportunities in a host of diverse areas.
Soil consolidation refers to the mechanical process by which soil changes volume gradually in response to a change in pressure. This happens because soil is a two-phase material, comprising soil grains and pore fluid, usually groundwater. When soil saturated with water is subjected to an increase in pressure, the high volumetric stiffness of water compared to the soil matrix means that the water initially absorbs all the change in pressure without changing volume, creating excess pore water pressure. As water diffuses away from regions of high pressure due to seepage , the soil matrix gradually takes up the pressure change and shrinks in volume. The theoretical framework of consolidation is therefore closely related to the diffusion equation , the concept of effective stress , and hydraulic conductivity. In the narrow sense, "consolidation" refers strictly to this delayed volumetric response to pressure change due to gradual movement of water. Some publications also use "consolidation" in the broad sense, to refer to any process by which soil changes volume due to a change in applied pressure.
Melting Permafrost Poses Challenge For Arctic Companies
It is a flagship campus of the University of Alaska system. UAF was established in and opened for classes in Fairbanks-based programs became the University of Alaska Fairbanks in UAF's research specialties are renowned worldwide, most notably Arctic biology , Arctic engineering , geophysics , supercomputing , Ethnobotany and Alaska Native studies.
Loess is a silt-sized, aeolian sediment that was produced in large quantities in past geological eras of mid-latitude Europe and Asia, among others Fig. It is used in Quaternary science to infer about past climatic and environmental conditions. These soils get buried again under a new loess layer once the warmer period is over. One such example is presented in our previous blog post.
