Sustainability - answer-✔When a natural system or resource has reached a certain
level or balance that enables it to function properly and exist for an extended
period of time.
Example of Sustainability - answer-✔water sustainability: a confined aquifer that
has been allowed time to recharge without humans interfering with the natural
process
Transpiration - answer-✔Process by which water is directly evaporated from soil
or plants and other forms of vegetation
Example of Transpiration - answer-✔fertile soil along the bank of a river from
which water is transferred into the atmosphere
Watershed - answer-✔An area of land that drains all its streams and rainfall into a
common outlet
Example of Watershed - answer-✔Lake Erie Watershed
Confined Aquifer - answer-✔Underground body of water that is surrounded by
confining layers of non-permeable materials such as rock or hard clay - prevents
water from flowing in and out except through a single recharge area - far below the
surface
Example of Confined Aquifer - answer-✔centuries old aquifer far below the water
table surrounded by stone
, Unconfined Aquifer - answer-✔Underground body of water that has the water table
as its upper boundary and permeable materials as its lower boundary - closer to the
ground surface
Example of Unconfined Aquifer - answer-✔an aquifer being pumped into a well -
coastal sands and alluvial deposits in river valleys
(Conservation of) Mass Balance Equation - answer-✔dV/dt = I-O
Example of Mass Balance Equation - answer-✔The mass conservation law can be
described as the difference between the rate of inflow (I) and outflow (O) is equal
to the time rate of change of mass (dV/dt) inside of the control volume. V is the
volume of water within the control volume, I and O are volumetric inflow and
outflow rates, respectively.
Induced Recharge - answer-✔The recharge to an aquifer that occurs when a
pumping well creates a cone of depression that lowers an adjacent water table
below the level of a stream or lake, causing the stream or lake to lose water to the
adjacent groundwater aquifer.
Example of Induced Recharge - answer-✔The slow process of induced recharge is
being superceded by excessive pumping.
Water Footprint - answer-✔Your individual impact on the world's water resources
through your usage of water throughout your life or over a specific period of time
Example of Water Footprint - answer-✔the amount of water I use each week by
showering, washing dishes, doing laundry, eating food, etc.
