Gauge Height - the water-surface elevation referred<br />

to some arbitrary gauge datum. Gauge height is often<br />

valos de recurrencia de las inundaciones representados used interchangeably with the more general term<br />

graficamente <strong>com</strong>a la abscisa. stage although gauge height is more appropriate<br />

Inundacih, Mhima Probable - la inundacidn m&s when used with a reading on a gauge.<br />

grande que se puede esperar raronablemente en esta era Generator - a machine which converts mechanical<br />

climatica.<br />

energy into electric energy.<br />

Plano de Inundacidn - una faja de tierra relativamente<br />

llana, que bordea una corriente, hecha de sedimentos<br />

traidos por la corriente y abandonados en la ribera por el<br />

agua muerta y fuera de1 alcance de las corrientes m&s<br />

rapidas. Se le llama plano de inundation viviente si se in-<br />

unda cuando hay creciente pero se le llama zona de inun-<br />

dacion fosil si e&A fuera de1 alcance de la inundation mas<br />

alta.<br />

Ruta de las Crecientes - el proceso de determinar pro-<br />

gresivamente el tiempo y la forma de la ola de una cre-<br />

ciente a varios puntos sucesivos a lo largo de1 130.<br />

Combustible F&i1 - se refiere a carbon, petrdleo y gas<br />

natural.<br />

Elevacih en la Escala - la elevation de la superficie de1<br />

agua <strong>com</strong>parada con un data arbitrario de medicion. La<br />

elevation de la escala se usa frecuentemente intercam-<br />

biablemente con el termino mas general de1 nivel aunque<br />

la elevation de la escala es m&s adecuada cuando se la use<br />

con una lectura end calibrador.<br />

Generador - maquina que convierte la energia mecanica<br />

en energia electrica.<br />

Gigavatio (GV) - un millon de kilovatios.<br />

Agua Subterrhea -- agua en el subsuelo que es lencuen-<br />

tra en la zona de saturation de donde se alimentan 10s<br />

pozos, manantiales y caudales subterraneos.<br />

Efluencia de Agua Subterrinea - aquella parte de la<br />

descarga de una cuenca de drenaje que ocurre atravez de1<br />

agua subterranea. El tirmino “corriente subalvlea” es a<br />

menudo usado para describir la salida de1 agua<br />

subterranea que ocurre en aluviones sobre !os valles (en<br />

vez de atravez de 10s cauces de la superficie) y asi no se<br />

miden en una estacibn ralibradora.<br />

Aflueneia Subterrhnea - aquella parte de la afluencia<br />

que se ha submergido en el suelo y se convierte en agua<br />

subterranea y ha sido descargada dentro de1 cauce de la<br />

corriente en la forma de manantial o de agua filcrada.<br />

Caida Gruesa - la diferencia en alturaa entre la super-<br />

ficie de la caida y la superficie de1 agua de descarga deba-<br />

jo de una pianta hidroelectrica bajo condiciones<br />

especificadas.<br />

Planta Hidroelktrica o Planta de Hidroenergia - una<br />

I planta de energia electrica en la cual las turbinas y<br />

generadores son accionados por agua.<br />

Hidrografica - gr&fica que muestra nivel, flujo,<br />

velocidad u otra propiedad de1 agua con relation al<br />

tiempo.<br />

Gigawatt (GW) - one million kilowatts.<br />

Groundwater - water in the ground that is in the zone<br />

of saturation, from which welts, springs, and ground-<br />

water runoff are supplied.<br />

Groundwater Outflow - that part of the discharge<br />

from a drainage basin that occurs through the ground-<br />

water. The term “underflow” is often used to describe<br />

the groundwater outflow that takes place in valley<br />

alluvium (instead of the surface channel) and thus is<br />

not measured at a gauging station,<br />

Groundwater Runoff - that part of the runoff which<br />

has passed into the ground, has be<strong>com</strong>e groundwater<br />

and has been discharged into a stream channel as<br />

spring or seepage water.<br />

Head, Gross (H) - the difference in elevation between<br />

the headwater surface above and the tailwater surface<br />

below a hydroelectric power plant, under specified<br />

conditions.<br />

Hydroelectric Plant or <strong>Hydropower</strong> Plant - an electric<br />

power plant in which the turbine/generators are driven<br />

by water.<br />

Hydrograph - a graph showing stage, flow, velocity,<br />

or other property of water with respect to time.<br />

Hydrologic Budget - an accounting of the inflow to,<br />

outflow from, and storage in, a hydrologic unit, such<br />

as a drainage basin, aquifer, soil zone, lake, reservoir,<br />

or irrigation project.<br />

Hydrologic Cycle - a convenient term to denote the<br />

circulation of water from the sea, through the at-<br />

mosphere, to the land; and thence, with many delays,<br />

back to the sea by overland and subterranean routes,<br />

and in part by way of the atmosphere; also the many<br />

short circuits of the water that is returned to the at-<br />

mosphere without reaching the sea.<br />

Infiltration - the flow of a fluid into a substance<br />

through pores or small openings. It connotes flow into<br />

a substance in contradistinction to the word percola-<br />

tion, which connotes flow through a porous<br />

substance.<br />

Infiltration Capacity - the maximum rate at which the<br />

soil, when in a given condition, can absorb falling rain<br />

or melting snow.<br />

Installed Capacity - the total capacities shown on<br />

the nameplates of the generating units in a<br />

hydropower plant.<br />
