Freshwater is defined as having a low salt concentration — usually less than 1%. There are different types of freshwater regions:
• Ponds and lakes
• Streams and rivers
• Wetlands
Streams and rivers ( Floating ecosystem)
These are flowing water bodies moving in one direction. Streams and rivers can be found everywhere — their origin may be springs, snowmelt or even lakes, and then travel all the way to mouth, usually another water channel or the ocean. The characteristics of river or stream changes during their journey from their source to mouth. The temperature is much lower at the source as compared to its mouth. The water is clearer and has higher oxygen level. freshwater fishes such as trout and heterotrophs can be found. Towards the middle part of the stream/river, its width increases, and also its species diversity — many aquatic green plants and algae are found. Toward the mouth of the river/stream, the water

Lack of resources to operate wastewater treatment plant in most of the places is responsible for increasing pollution. A technology which uses natural resources is the only way out of this problem. One of such technology is Artificial Floating Island; it can treat the polluted river water along its course. It is nothing but, wetlands which floats on water surface with help of buoyant material. According to the surveys, the rivers in Pune city are perfect examples of polluted rivers in India. Discharge of raw sewage or partially treated waste water is the prime reason for water pollution. Artificial Floating Islands (AFI) can be effectively used in water bodies with organic pollutants. Therefore, AFI is can prove to be ideal system to control pollutions of rivers in India. AFI will help to retain the ecology of rivers; it is a robust and sustainable technique to treat river
Furthermore, the river starts as astream in the upper course and flows through valleys. The middle course, however, is where the river starts to become wider and deeper. The land, which the river flows over, is becoming flatter and this is where the river starts to meander or bend in the middle course. The lower course is where the river becomes its widest and deepest.
Water is the foundational basis of life on Earth. Ecosystems, society and humans are completely dependent on it, and as the world population continues to grow, there will be more mouths to feed, and those people will need water to continue their daily lives. However, shortages and poor management leads to the destruction of natural habitats and human suffering. Desertification of land in China is ever-increasing, turning green, lush land into desert. However, this is due mainly in part, because of human activity, and global warming (Wang, Yang, Dong, & Zhang, 2009). The United States could experience a crisis similarly to China’s, but for now they have averted such a catastrophe, because of heavy regulation of water. Though there are water shortages in many parts of the world, it is unwise to export water from the Great Lakes to those regions. Two major reasons why diverting the Great Lakes is a terrible idea, one: it allows for waters wars to start on the basis of who is allowed to access it and for commodification purposes. Two, diverting water on such large scales could have cataclysmic effects on the local residents as well as the environment.
Headwater streams are the peripheral reaches of larger river networks that make up between 50-70% of total reach length within the United States (Fritz et. al 2008). Headwater streams are a major component of river networks and are composed of small swales, creeks, and streams, which form the building blocks for large river and lakes. Headwater streams are very influential on the overall health of aquatic ecosystems, because they provide n...
A river or “stream, ribbons of water confined to channels, or troughs, cut into the land,” (Marshak, 2009) is formed from a drainage network or “the array of interconnecting streams” that form tributaries. (Marshak, 2009). The amount of water that flows down a stream is its discharge. The discharge measurement takes the width and depths or cross sectional area of a river as well as the downstream velocity to get a numeric value for amount of water moving down stream. (Marshak, 2009)
Alongside this nutrient flush, greater sediment deposition also occurs. This increased sediment load has a significant effect upon stream turbidity, reducing stream clarity and the ability of light to penetrate to lower depths. With the increase in stream turbidity, an increase in temperature of the hydrologic system can be observed. The darker colouration of the stream, as a result of the deposition, results in increased absorption of solar
The main problem that the lagoon is facing is pollution from runoff and freshwater inputs such as Taylor Creek or Lake Okeechobee. Some of this pollution is nutrient pollution, which promotes bacterial growth and needless to say, causes some problems. The other type of pollution, This essay with describe such affects and what you can do to stop the degrading ecosystem known as the Indian River Lagoon from falling into an irreversible pollution
Rivers represent eternity and the transitions of life. Heraclitus, a Greek philosopher, stated, “No man ever steps in the same river twice, for it 's not the same river and he 's not the same man”. In the concept of Buddhism, the river is a symbol of life cycles. One cannot leave
a Watershed is an area of land where all of the water that is under it, or drains off of it collects into the same place. Most of the watersheds in Idaho are part of the Columbia River Basin Watershed, which drains into the Pacific Ocean big cities use a lot of water and when they use too much the place they get the water from might run out.
Living in a world that is roughly 70% water, and all living creatures found on this planet depend on this resource whether directly or indirectly, making water quality an important topic and vital to sustain our world of cycles. “Determination of status of water quality of a river or any other water sources is highly indeterminate. It is necessary to have a competent model to predict the status of water quality and to advice for type of water treatment for meeting different demands.” (Bai V, 2009) With most of our water on this planet made of salt water and our constant damage towards the remaining water that can be consumed by humans is diminishing with improper distribution on a global scale. If our greed comes before companionship, and our quality of life is more important than pollution, then our future generations to come will be born into a world of chaos, and a scarce of a basic human necessity.
For Shiva, the roots of her argument come from a conflict over two different ideological beliefs. One sees water as a common resource that should be freely available and conscientiously conserved; the other sees water as a market good to be possessed, bought and sold. The market proponents argue that the water crisis can be alleviated by privatizing water: places with more water can sell to places with less water and the higher prices will lead to conservation even though those who control the water.
If the gradient is steep (like the example on the right) then this can indicate that the amount of rainfall becoming overland flow is very high, the result of this is that all the water reaches the river very quickly and all in a short period of time, this gives the immediate steep ascending limb on the hydrograph. Reasons for large amounts of rainfall becoming overland flow can be little vegetation and maybe impermeable rock below the surface. Being impermeable rock, the water cannot infiltrate through this and become ground water, instead it flows over the ground to the river. Urban development and agricultural practices contribute to overland flow.
The average human can not live any longer than three days without water. Many of the world’s fresh water sources are running dry or are being contaminated, particularly in developing nations, leaving many without safe water to drink. Only two and a half percent of the Earth’s water is freshwater, and less than one percent is accessible by humans (not tied up in ice caps). This one percent of the Earth’s water supply is expected to sustain a population of over 7 billion people, each needing 2.6 liters a day to remain fully healthy, plus all of the water required for agriculture and industry. These scenarios will only become more and more prevalent as time moves on and we consume more water. The United Nations has classified our planet as being in the midst of a global “water crisis.” Global water supply and shortages are becoming an incredibly real and serious issue, and planning for the future is key to preventing population decline due to a lack of safe drinking water. Shortages of drinking water lead to wars and serious international conflict for basic human survival needs. One of the most popularly and commonly proposed solutions to this problem is to create seawater desalination plants to remove salt from ocean water to make it safe to drink. These water desalination plants, however, are not a viable option to carry us in to the future due to their potentially harmful impacts and expenses.
Today's waters are constantly being treated like sewage dumps or trash cans. We use them as garbage cans every day polluting the water more and more. "Pollution is often by way of rivers, drains and outflow pipes." Causing an outflow of sewage into our ocean waters. This is not only affecting the community but also the marine life and other sea creatures living in the ocean." This pollution includes human sewage and domestic waste water, factory outflows of acids and poisonous metals, engine oil from roadside drains and garages, farm chemicals washed off the land by rain, building-site rubble, nuclear waste from power plants, and oil from wells, refineries, and tankers." Stating that most of today's waste is from factory or factory ran products that shouldn't be polluting the water
The fresh water is very important for all humans, animals, and all living organisms. After the air, water is the most essential component on the earth to sustain life. The main sources of water on the earth are rivers, lakes, underground water, springs, glaciers etc. The total amount of water required for drinking depends on the age of the humans, environmental conditions (eg. summer, winter), availability and the quality of water etc. All living things require water for the survival. Water is used for several activities like drinking, cooking, washing cloths and cleaning floors , gardening and industrial purposes. Water is not only used for the drinking purpose but it is also used for growing vegetation
Water is an irreplaceable natural resource on this earth which comprises marine, estuarine, fresh water (river and lakes), ground water across coastal and inland areas. Even though there is huge water resource in this world, about 97% of water is salt water (marine) only 3% is fresh water. And in this small fraction of fresh water a major part is in the form of ice in polar region. So just 0.003% is in the form of ground water and surface water which we can use.
