Atterberg Limits describe the water contents at which clays change behavior. The water content indicating the division between the liquid and plastic state is the liquid limit. The Liquid Limit is determined using a brass ...
Unconfined Compression Test
The unconfined compression test. Collect approcimately 1200g of soil passing through the No. 4 Sieve. Add water and mix soil sample thoroughly. Weigh empty Harvard Miniature Mold and place layer of soil in mold. Compact ...
The pressure that a foundation unit can impose onto the supporting earth mass without causing overstressing (or shear failure) is the soil's bearing capacity. The three principal modes of soil failure established by the ...
Categorizing Sedimentary Rocks by Origin
Using examples, this video tells students what to look for in order to identify rocks.
Sea level rise and inundation of island interiors: Assessing impacts of lake formation and evaporation on water resources in arid climates
Coasts of many low-lying islands will be inundated should sea level rise by 1 m by 2100 as projected, thereby decreasing water resources through aquifer salinization. A lesser known impact occurs if rising sea level elevates ...
Forest restoration as a strategy to mitigate climate impacts on wildfire, vegetation, and water in semiarid forests
Climate change and wildfire are interacting to drive vegetation change and potentially reduce water quantity and quality in the southwestern United States, Forest restoration is a management approach that could mitigate ...
Experimental and numerical investigation of saltwater intrusion dynamics in flux-controlled groundwater systems
Sea level rise and reduction of groundwater fluxes due to changes in rainfall patterns are the two major climate change–induced hydrological variables that can severely affect saltwater intrusion in coastal aquifers. In ...
