To answer this question it is necessary to go back in the history of the hydraulic machines .
the first hydraulic mills were big wheels turning slowly . the water supply was a level canal catching one part of the water on the side of the river and going near the mill construction in a dam.This hydraulique mills had no bad impact on environment.
Later the evolution of technic changed the wheels and put a hydro power devise which used higher pressure and faster speed of water.This hydro power supply recieve the water by high pressure tube from a dam conctructed on the river. This second hydrolic power had i bad impact on environment on the river an and fishes.
The wheel mills are good and can be used with modern mechanical .
THe explanation is important to give the good comments to convince the project partners
To make more you can developp hydraulic power by applying the globale water management.
http://video.google.fr/videoplay?docid=-鈥?/a>What are the problems arising in the environmental impact assesment of hydro power projects?Hydro power projects mainly affects the Aquatic Ecosystem and
Land use pattern due to Dam and subsequently initiate the social issues.
Other issues are temporary and restricted during the construction phases only.What are the problems arising in the environmental impact assesment of hydro power projects?The major aquatic problems are changing the downstream temperature and flow problems (both seasonally and daily), blocking or modifying the migration pattern of fish past the power plant structure, injury to fish and other organisms passing through the turbines, and disruption of the spawning of fish and productivity of invertebrates downstream, elimination of flowing water upstream in the area of dam construction (if any) and so changing the habitat (including both temperature regime and current patterns) potentially changing the species composition.
Terrestrial impacts include the elimination of habitat in the area occupied by the power plant and continuing disruptions related to the operation of the power plant, supporting structures, road access and power transmission lines. If in a pristine area, the roads and transmission lines may increase access by humans not associated with the project and result in secondary impacts from their activities.What are the problems arising in the environmental impact assesment of hydro power projects?te so called important trees are getting destroyed

What are the problems in agriculture today?
What are some other problems/controversies besides Environmental effects?What are the problems in agriculture today?1.Non-availability of good fertilizers
2.High cost of farming instruments and vehicles
3.Getting good market for the farmers
4.Unscientific farming
and lot lot more..Just search wikipedia for moreWhat are the problems in agriculture today?
Fewer family farms mean fewer of today's youth growing up on farms. Kids raised in the country have a different view of the world. They are given more responsibilities at younger ages. How many city parents (suburban soccer moms) would let their 11 or 12 yr old son/daughter drive a $500,000 combine down the road? Or a 80,000lb semi loaded with grain. It happens all the time in the country. These kids grow up knowing that they can do things that many people are afraid to even try. A great country needs to have sufficient amount of old-fashioned farm boy/girl logic and ingenuity. I think the loss of rural raised farm families is a serious problem in agriculture today.What are the problems in agriculture today?It is possible to enumerate hundreds of problems related to agriculture. I will give 2 generalizations:
1. How to increase yields per unit area in order to feed the expected influx of population into the urban centers. This is the reason for the recently proposed farming technology called Vertical Farming.
2. How to increase world food production in order to cope up with the continuing rise in world population. It is computed that if we will go back to the natural way of finding our food as the primitive man did, only 2 out 1000 will survive in 2011.What are the problems in agriculture today?
HSUS, PETA, ALF, ELF, and MFA propaganda. They are trying to ban animal agriculture, one step at a time. HSUS is the most effective because they are not "radicals", and they have "humane society" in their name, as well as being government funded. Eventually they want to make it to where it is illegal to own a pet. I know it sounds as if I am becoming radical, but in interviews with Wayne Parcel, HSUS CEO, it is hinted towards that, EVENTUALLY.What are the problems in agriculture today?If we are talking about America, I'd say it would be the death of the family farmer and the rise of the corporate farm. In 1935 there were 6.8 million farms in the US. In 2002 there were 2.1 million farms. The problem with this is a scenario similar to the salmonella outbreak that happened in the egg industry recently. There were very large farms who supplied MANY states with eggs. One mistake has a national impact, not just local or regional.

Is there an environmental or other problem with the houses in Wilshire Walk in Newtown Pa.?
I doubt all the houses have environmental issues.acura tsx
Biogas residue cause any environmental problem?
Hello
have question about biogas residue , what is the CHARACTERISTIC
of it and can biogas residue cause any environmental problemBiogas residue cause any environmental problem?it has been proven that biogas is safe and very efficient. so it's advantages outway any disadvantage it has although i haven't read any apart fear of global food shortage

Has organic chemistry caused problems?
Does anyone know of an incident in which organic chemistry has caused severe health or environmental problems. How were these problems fixed?
An example of the sort of thing I'm looking for is the damage to the ozone layer caused by CFC's - the gases used in early refragerators.
thanksHas organic chemistry caused problems?Mustard Gas. is a toxic Alkyl Halide that was used in the WW. it is Cl-CH2-CH2-S-CH-CH2CL
Give me 10 points =).Has organic chemistry caused problems?Look up Bhopal India. There was a release of methyl isocyanate that led to many deaths.

Potential solution to a serious environmental problem that has to do with energy use?
please help!!! any help would be great!Potential solution to a serious environmental problem that has to do with energy use?There are many problems and solutions that have to do with energy use. Probably the largest is the emission of CO2 (causing global warming) when fossil fuels are burnt. The solution is a process which turns the fossil fuel (coal, oil or natural gas) into hydrogen and CO2. The CO2 can be separated out and pumped deep underground. The hydrogen can then be transported in liquid or gaseous form and used as a fuel in cars, homes or power stations.
The process for converting fossil fuels into hydrogen and CO2 (steam reforming) is already widely used in industry.

or are you asking us to give you a problem, and its solution?Potential solution to a serious environmental problem that has to do with energy use?Yea you need to reword your question to state the problem you want people to suggest a solution for!

List one environmental problem with harvesting?
farming uses pesticides which can enter the ground water and people could end up getting sick.List one environmental problem with harvesting?yes, that can occur, but only if used improperly.
proper use of pesticides is 100% safe for people and environment (except the pests of course).
even with "organic" farming improper use of fertilizing materials, etc. can have serious adverse effects on people and the environment so it's not the method or the materials...it's the user.
oh...and an environmental problem with harvesting....you can leave open ground and soil can be more susceptible to runoff and erosion.
