1) flood_water_thickness | |
The flood_water_thickness is the vertical distance | |
between the surface of the flood water and the surface of ground, | |
as measured at a given point in space. | |
The flood_water is water that covers land | |
which is normally not covered by water. | |
Canonical Units: m | |
2) flood_water_speed | |
Speed is the magnitude of velocity. | |
The flood_water is water that covers land | |
which is normally not covered by water. | |
Canonical Units: m.s-1 | |
3) eastward_flood_water_velocity | |
A velocity is a vector quantity. | |
"Eastward" indicates a vector component | |
which is positive when directed eastward (negative westward). | |
The flood_water is water that covers land | |
which is normally not covered by water. | |
Canonical Units: m.s-1 | |
4) northward_flood_water_velocity | |
A velocity is a vector quantity. | |
"Northward" indicates a vector component which is positive when directed | |
northward (negative southward). | |
The flood_water is water that covers land | |
which is normally not covered by water. | |
Canonical Units: m.s-1 | |
5) ground_level_altitude | |
The ground_level_altitude is the geometric height of | |
the upper boundary of the solid Earth above the geoid, | |
which is the reference geopotentisal surface. | |
The geoid is similar to mean sea level. | |
Canonical Units: m | |
Rationale: the CF standard name table already has | |
a name ``surface_altitude'', but in this case the surface is defined as | |
the lower boundary of the atmosphere. | |
In the flood water simulation the levels do not match. | |
6) time_when_flood_water_rises_above_threshold | |
The time_when_flood_water_rises_above_threshold is the time elapsed | |
from the break or the overflow of levee (origin of flood water simulation) | |
until the flood water rises above a given threshold to a given point in space. | |
The threshold should be given by a coordinate variable | |
or a scalar coordinate variable | |
having the standard name "flood_water_thickness"; | |
otherwise it defaults to zero. | |
The flood_water is water that covers land | |
which is normally not covered by water. | |
Canonical Units: s | |
7) time_of_maximum_flood_depth | |
The time_of_maximum_flood_depth is the time elapsed | |
from the break or the overflow of levee (origin of flood water simulation) | |
until the time when the flood water thickness reaches to the maximum | |
during the simulation for a given point in space. | |
The threshold must be given in a coordinate variable | |
or a scalar coordinate variable | |
having the standard name "flood_water_thickness". | |
The flood_water is water that covers land | |
which is normally not covered by water. | |
Canonical Units: s | |
8) time_when_flood_water_falls_below_threshold | |
The time_when_flood_water_falls_below_threshold is the time elapsed | |
from the break or the overflow of levee (origin of flood water simulation) | |
until the time when the flood water falls below | |
a given threshold for a given point in space. | |
The threshold should be given by a coordinate variable | |
or a scalar coordinate variable | |
having the standard name "flood_water_thickness"; | |
otherwise it defaults to zero. | |
The flood_water is water that covers land | |
which is normally not covered by water. | |
Canonical Units: s | |
9) flood_water_duration_above_threshold | |
The flood_water_duration_above_threshold is the time elapsed | |
from the time when the flood water firstly rises above a given threshold | |
until the time when the flood water finally falls below the threshold | |
for a given point in space. | |
The threshold should be given by a coordinate variable | |
or a scalar coordinate variable | |
having the standard name "flood_water_thickness"; | |
otherwise it defaults to zero. | |
The flood_water is water that covers land | |
which is normally not covered by water. | |
Canonical Units: s | |
