You may have seen this beautiful sculpture as you
descended/ascended the Spanish Steps. This area is distinct in
character although not separate geographically and provides you an
excellent opportunity to learn about a hidden geological gem.
As you walk around you will notice that this is actually a fresh
water spring that is entirely drinkable. Many take advantage to
fill there bottles and sample the cool fresh taste of this
wonderful naturally occuring spring since they are already here to
admire the touristy stuff as well. This water is transported via
aqueduct, bringing water from the Salone Springs, nearly 20
kilometres from Rome. What is even more amazing is the remarkable
quality of this water source.
While you are here, feel free to take a picture of yourself to
share with us in your log.
The area is quite interesting, since it is below the normal
water level and so was subject to a tremendous amount of flooding
from the Tiber River until walls were built. In 1598 there was a
horrible flood and a boat was brought into the Piazza di Spagna and
so in memory of that event, this monument was created. Taking
advantage of the cool fresh water that comes such a long way to
enter the middle of the city.
In order to log this Earthcache there are a couple things that
are needed:
1. Use a container of measurable volume and a stopwatch to
calculate how many liters per hour come from the spring? Please
take readings from all points as they vary in volume and will
affect your overall measurement. Please do not attempt to climb
into the fountain for the central sources, make a hypothesis for
these if you are unable to reach them safely.
2. What magnitude would that make this spring based on the chart
below?
1st Magnitude = (greater than 100 cfs* or 64.6 MGD^)
2nd Magnitude = (less than 100 cfs to greater than 10cfs or less
than 64.6 to greater than 6.4 MGD)
3rd Magnitude = (less than 10 to greater than 1 cfs or less than
6.4 to greater than 0.64 MGD)
4th Magnitude = (less than 1cfs to greater than 100 gal/min)
5th Magnitude = (less than 100 gal/min to greater than 10
gal/min)
6th Magnitude = (less than 10 gal/min to greater than 1
gal/min)
7th Magnitude = (less than 1 gal/min to greater than 1
pint/min)
8th Magnitude = (less than 1 pint/min)
*cfs = cubic feet per second
^MGD = million of gallons per day
Please email me the answers to these questions, do not post them
in you log or it will be removed.
