Si reD< 0.5 Utilizamos la variacion Lineal metoda LIBP

En nuestro caso Utilizamos el radio de drenaje adimensional determinado en la tabla 8

para acufferos radiales Leung para un radio de drene reD = 2.8 tenemos un valor de 0.

En las secciones anteriores fueron presentados varios model os para el calculo de la

entrada de agua acumulada proveniente de 105 acufferos. Cada uno de 105 modelos fue

utilizado para estimar el influjo acumulado del acuffero circular limitado. Para cada unode 105 modelos, se calculo en base al tiempo, el influjo acumulado del acuffero sujeto a

un historial de presion variable en el contacto. Los resultados estan presentados en la

tabla 8.11.

Many g!JimoJ$are in danger of

destroying the rainforests,~---

The -Lavclnrhinoceros one lived

in the rainforests of many

countries: in the north of India,

through ~0do-China and ~u.:tb

tbrougb Malaysia and the [slands

of Indonesia. But today there are

only about one thousand of these

animals in the world, some living

in Vietnam and some living in the

Ujung Kulon NationaLforest Parkon the island of Java , where forest

workers protect them.

Today, there are many forest

park in the rainforests of the

world. Animals need(~e parks"

because some ~p-e~l~$.have to travel

many B i J ( ) . !11~ lr _ ? S _ to find food. The

Par'~ Nationaldes ~I}~ in

Rwanda, for e > 5 .q j'n p - J ~ , protects the

mountain gorilla and saves it from~---extinction.

(~) When you vjsit a pet shop, ask

about the animals there. D,id

somebody catch any of them in the

rainforests, put them into boxes,

and fly them to the pet shop)

Zoos in many countries of the----

VJorldare helping to p-rotect ..

animals in danger. The golden lion

tamarin comes from f?r:'.aziJ's.fol'est

near the sea.

( G The forest there is'-'

disappearing fast and people

caught hundreds of these tamar ins

and sold them in pet shops. There

were only a few left in the

rainforest. But many golden lion

tamarins were born in zoos, and

scientists have taken some of them

back to the Poco das Antas forest

Park near Rio..9s.janeiro.

/~ f ) Animals born in zoos know'-' nothing a_~out)life in the

away from danger. Janis Cartel'
