CHAPTER 0 - terms from “what could go wrong reading” Flashcards
(26 cards)
capillary action
pulling of water through a small orifice or fibrous material by the attractive force between the water and the material
condensation
process of changing from a gaseous to a liquid state, especially as applied to water
decay/rot
lose integrity, etc.
dewatering
extraction of water from an excavation or its surrounding soil
drainage swale
A grass drainage swale is an open channel that collects water from hard surfaces and allows it to percolate into the ground, reducing the amount of runoff leaving the road or property. The grass covering the side slopes and swale bottom provides a filtration surface for the water and helps to reduce the flow velocity.
faults/fault lines
A fault trace or fault line is a place where the fault can be seen or mapped on the surface. A fault trace is also the line commonly plotted on geologic maps to represent a fault. A fault zone is a cluster of parallel faults. However, the term is also used for the zone of crushed rock along a single fault
fire season
Period(s) of the year during which wildland fires are likely to occur, spread, and affect resource values sufficient to warrant organized fire management activities. 2) A legally enacted time during which burning activities are regulated by state or local authority.
frost heave
Frost heave is a form of frost action, a physical weathering process involving the cyclic freezing and thawing of water in soil or rock. Heave in this context refers to the upward movement of the ground surface that occurs in response to the seasonal formation of ice in the underlying soil.
fungi
Mould (sometimes referred to as mildew) is a fungal growth. … Mould in buildings can be visible or can be hidden, but it is generally an indication of a defect such as thermal bridging, condensation, leaks or penetrating or rising damp. Mould requires four factors for growth: Mould spores.
induced earthquakes
Induced seismicity refers to typically minor earthquakes and tremors that are caused by human activity that alters the stresses and strains on Earth’s crust. Most induced seismicity is of a low magnitude.
interface fire
Interface fire - Interface fires are fires that have the potential to involve buildings and forest fuel or vegetation simultaneously.
liquéfaction/liquify
Liquefaction is a phenomenon in which the strength and stiffness of a soil is reduced by earthquake shaking or other rapid loading. … Liquefaction occurs in saturated soils, that is, soils in which the space between individual particles is completely filled with water.
live load
non permanent loads on a building caused by the weights of people, furnishings, machines, vehicles and goods in or on the building
magnitude
Magnitude is the most common measure of an earthquake’s size. It is a measure of the size of the earthquake source and is the same number no matter where you are or what the shaking feels like.
mold
either a fungus or a thing made of plaster used as a cast
oscillations
regular variation in magnitude or position around a central point
osmosis
osmosis, the spontaneous passage or diffusion of water or other solvents through a semipermeable membrane (one that blocks the passage of dissolved substances—i.e., solutes).
percolate
(of a liquid or gas) filter gradually through a porous surface or substance.
“the water percolating through the soil may leach out minerals”
remediation
the action of remedying something, in particular of reversing or stopping environmental damage.
the giving of remedial teaching or therapy.
seismic
relating to earthquakes
storm surge
Storm surge is an abnormal rise of water generated by a storm, over and above the predicted astronomical tides. … This rise in water level can cause extreme flooding in coastal areas particularly when storm surge coincides with normal high tide, resulting in storm tides reaching up to 20 feet or more in some cases.
vapor pressure
a measure of the pressure exerted by water molecules in a gaseous state, generally higher with higher relative humidity and higher air temperature
water vapor
water in its gaseous phase
wetlands
land consisting of marshes or swamps; saturated land.
