municipales, energia 0 irrigation en contraste con<br />

almacenamiento de la capacidad utilizado para control de<br />

las inundaciones.<br />

Us0 Consumptivo - la cantidad de agua absorbida por la<br />

cosecha y transpirada o usada directamente en 10s tejidos<br />

de las plantas juntamente con la evaporada de1 5rea de la<br />

cosecha.<br />

La cantidad de agua transpirada y evaporada de un area<br />

de la cosecha o la perdida normal de agua de1 suelo por<br />

evaporation y transpiracidn de la planta.<br />

La cantidad de agua descargada a la atmosfera o incor-<br />

porada en 10s productos de1 proceso en coneccion con el<br />

crecimient vegetative, proceso de alimentos, 0 un proceso<br />

industrial.<br />

Contenido - el volumen de agua en un reservorio. A<br />

menos que se indique de otro modo, el contenido de un<br />

reservorio se <strong>com</strong>puta en la base de una pileta a nivel y no<br />

incluye el almacenaje de1 banco.<br />

Control - una constriction natural de cauce, una exten-<br />

sion larga de1 cauce, un estrecho de 10s “rapidos”, o una<br />

estructura artifical corriente abajo de una estacidn de<br />

medicion que determina la relation de1 nivel a la descarga<br />

al punto de la medicion.<br />

Un control puede ser <strong>com</strong>plete o partial. Existe control<br />

<strong>com</strong>plete cuando la relation nivel descarga en la estacion<br />

de medicion es totalmente independiente de las fluctua-<br />

ciones en el nivel mas abajo de1 control. Existe control<br />

partial cuando las fluctuaciones de la baja corriente tienen<br />

algun efecto sobre la relation de1 nivel descarga en la<br />

estacion de medicibn. El control, fuere partial o <strong>com</strong>plete,<br />

puede ser variable. La mayor% de 10s controles naturales<br />

son variables a cierto g-r&, pero existe control variable<br />

cuando la relacidn de1 nivel descarga experimenta fre-<br />

cuentes cambios debidos a la impermanencia de las cuen-<br />

cas o 10s bancos.<br />

Correlach - el proceso de establecer una relation entre<br />

un variante y una o mas variantes relacionadas. La cor-<br />

relation es simple si hay una sola variante independiente;<br />

multiple, si hay mas de una variante independiente. Para<br />

10s registros de la estacion de medicion, las variantes<br />

usuales son 10s regist,ros de la estacidn de medicion a cor-<br />

to plazo y uno o mas registros de la estacion de medieidn<br />

a largo plaza.<br />

Estimacih Correlativa - una descarga determinada por<br />

corre!acion. Una estimation correlativa representa un<br />

valor aproximado de la descarga para un perfodo par-<br />

ticular - <strong>com</strong>unmente un mes - de acuerdo a un metodo<br />

de analisis especifica;o.<br />

Costo (Econbmico) - la serie de valores requeridos para<br />

producir energia hidroelectrica. In proyectos<br />

hidroelectricos pequeiios, esto se limita a menudo a 10s<br />

costos de administration y construction requeridos para<br />

desarrollar la planta de energia, y 10s costos de<br />

administracibn, operaciones, mantenimiento y repuestos<br />

The quantity of water transpired and evaporated<br />

from a cropped area or the normal loss of water from<br />

the soil by evaporation and plant transpiration.<br />

The quantity of water discharged to the atmosphere<br />

or incorporated in the products of the process in con-<br />

nection with vegetati je growth, food processing, or an<br />

industrial process.<br />

Contents - the volume of water in a reservoir. Unless<br />

otherwise indicated reservoir content is <strong>com</strong>puted on<br />

the basis of a level pool and does not include bank<br />

storage.<br />

Control - a natural constriction of the channel, a<br />

long reach of the channel, a stretch of rapids, or an<br />

artificial structure downstream from a gauging station<br />

that determines the stage-discharge relation at the<br />

gauge.<br />

A control may be <strong>com</strong>plete or partial. A <strong>com</strong>plete<br />

control exists where the stage-discharge relation at a<br />

gauging station is entirely independent of fluctuations<br />

in stage downstream from the control. A partial con-<br />

trol exists where downstream fluctuations have some<br />

effect upon the stage-discharge relation at a gauging<br />

station. A control, either partial or <strong>com</strong>plete, may also<br />

be shifting. Most natural controls are shifting to a<br />

degree, but a shifting control exists where the stage-<br />

discharge relation experiences frequent changes ow-<br />

ing to impermanent bed or banks.<br />

Correlation - the process of establishing a relation<br />

between a variable and one or more related variables.<br />

Correlation is simple if there is only one independent<br />

variable; multiple, if there is more than one indepen-<br />

dent variab!e. For gauging station records, the usual<br />

variables are the short-term gauging-station record<br />

and one or more long-term gauging station records.<br />

Correlative Estimate - a discharge determined by<br />

correlation. A correlative estimate represents a likely<br />

value of the discharge for any particular period -<br />

<strong>com</strong>monly a month - according to a specified<br />

method of analysis.<br />

Cost (Economic) -the stream of value required to pro-<br />

duce the hydroelectric power. In small hydro projects,<br />

this is often limited to the management and construc-<br />

tion cost required to develop the power plant, and the<br />

administration, operations, maintenance and replace-<br />

ment costs required to continue the power plant in<br />

service.<br />

Cost of Service - cost of producing electric energy at<br />

the point of the ownership transfer.<br />

Critical Streamflow - the amount of streamflow<br />

available for hydroelectric power generation during the<br />

most adverse streamflow period.<br />

Current Meter - an instrument for measuring the<br />

speed of flowing water.<br />
