HYDRAULIC GAME

I just discovered a game of a reservoir. It´s a game of hability and is a bit difficult but it´s funny when you catch the trick :)

Hydraulic book

I have discovered a book of hydraulic power!  The link is: http://books.google.es/books?id=9JMsyTymCgwC&printsec=frontcover&hl=es#v=onepage&q&f=false    ---->  Copy and paste

The book is in English of course :)

This is the cover of the book

What´s a dam?

A dam is the accumulation of water caused by a blockage in the bed of a river or stream that partially or fully closed track.

 Channel obstruction can occur by natural causes such as the collapse of a hillside in a stretch of river. The accumulation of ice sheets or buildings made by beavers, and man-made works.

 ENVIRONMENTAL IMPACTS :

-Silt accumulation. 

-Changes in water quality of the reservoir and the river. downstream.

-Large losses of fish.

-Limitation of storage capacity of the river.

-Are increased water-related diseases (such as malaria, schistosomiasis)

-Health problems.

-Competition for resources.

-Social conflicts 

-Negative environmental impacts to the watershed, the reservoir and the downstream river valley.

-Flooded areas

VOLUMES OF A DAM

Death volume: Volume stored up to the minimum level.

Useful volume: This between the minimum and the maximum.

Volume rolling: Is between the maximum and the maximum normal level. This volume is used to reduce the flow and to limit damage downstream.

 USES OF A DAM

Basically a reservoir created by a dam, which disrupts the natural flow of a river, made ​​available to the operator of the reservoir storage volume potential that can be used for multiple purposes, some other complementary and mutually conflicting, provides reservoir operator is also a potential energy resulting from the lifting of the water level.

For applications that require maximizing the reservoir is as full as possible, ensuring a more regularized flow. These uses include power generation, irrigation, drinking water supply or industrial, dilution of pollutants. By contrast, for flood control reservoir will be more efficient as more vacuum is at the moment it receives a drag.

CHARACTERISTICS OF DAMS

The main physical characteristics of a reservoir are bound-volume curves, curve-surface elevation and flow regularized flooded.

Depending on the characteristics of the valley, if this is wide open, flood areas can occupy densely populated areas or fertile agricultural areas.

And finally I leave you a very nice picture of a dam :)

-I decided to publish on the blog dams because I think that they are a very important part of hydropower. 

PS: I hope you liked the new blog design :)

Hydraulic Energy

Here I put some information of hydraulic energy. It´s all in English, and there are a lot of information about other energies too. Hydraulic Energy
Esther Díaz.

This is a work of class that we did, this is in Spanish but it contains a lot of information.

Hydraulic transmission of force and energy

If you need to know a bit like it works this energy in this video explains it to the perfection and that uses instruments for his utilization.

WAVE POWER

INTRODUCTION

Ocean waves are caused by the wind as it blows across the sea. Waves are a powerful source of energy.

The problem is that it's not easy to harness this energy and convert it into electricity in large amounts. Thus, wave power stations are rare.

 HOW IT WORKS 

There are several methods of getting energy from waves.

One of them works like a swimming pool wave machine in reverse.

At a wave power station, the waves arriving cause the water in the chamber to rise and fall, which means that air is forced in and out of the hole in the top of the chamber. We place a turbine in this hole, which is turned by the air rushing in and out. The turbine turns a generator. A problem with this design is that the rushing air can be very noisy, unless a silencer is fitted to the turbine. The noise is not a huge problem anyway, as the waves make quite a bit of noise themselves.

this a video for see how it works the wave power

Wave power: the ocean energy

This energy is pruced by the waves. Its the waves change their height we get energy. Here I put a link explaining it better with some videos here

Some information for the begining

Here I put some information of hydraulic energy, this link is in spanish but is a very good definition for this energy. http://www.energiahidraulica.com/

Welcome!!

Hello! We are Ester,Gerardo,César,Silvia,Esther and Pablo. We have created this blog for everything that one that wants information about both energies: hydraulic and wave. It is for a work of class and we hope that it uses you as help for any information.
