Trees filter sewage and farm chemicals‚ reduce the effects of animal wastes‚ clean roadside spills and clean water runoff into streams. 3. Trees Control Noise Pollution Trees muffle urban noise almost as effectively as stone walls. Trees‚ planted at strategic points in a neighborhood or around your house‚ can abate major noises from freeways and airports. 4. Trees Slow Storm Water Runoff Flash flooding can be dramatically reduced by a forest or by planting trees. One Colorado blue spruce‚ either

While the nature takes from 100 to 400 years to build one centimetre of top soil‚ man can and often does destroy it almost overnight by haphazard land use and improvident husbandry. Irrational methods of cultivation‚ deforestation‚ destruction of natural vegetation due to overgrazing by pasturing animals etc.‚ accelerate denudation. Besides‚ failure of rains‚ floods‚ depopulation and loss of cattle caused by famine and pestilence‚ disturbance caused by war and interference with or change

Have you ever had the flu? If you have you know all the symptoms like headaches‚ sore throat‚ dizziness‚ and vomiting. The symptoms are miserable! What if one day you decided to take a nice swim in Lake Erie‚ and a couple hours after swimming these symptoms started occurring? Im sure you would not be happy! In the article “See Striking New Images of Algae Blooms in the Great Lakes” by Mia Tramz (Time Magazine) said‚ “Lake Erie is In danger of dying by suffocation‚ said‚and only we can stop it.”

CONCLUSIONS………………………………………………………………………………………………………………………....12 VI. REFERENCES…………………………………………………………………………………………………………………………....13 Abstract This project looks at a select watershed in Michigan and how the various characteristics of that watershed affect runoff from predicted storms. The chosen watershed was the Tobacco River that flows into Lake Superior Tasks were performed to first delineate the watershed‚ calculate the soil and land use‚ use that data to predict a 100 year storm‚ and to delineate the

whereas‚ the LEDC (Bangladesh) was affected much worse. Heavy rainfall of 200mm fell over Carlisle in a 36 hour period. The constant rainfall increased runoff because soil became saturated‚ this runoff ended up flowing into the river Eden. Because Carlisle is a largely urban area‚ concrete ground made from impermeable materials meant that surface runoff increased. There was a lot of discharge from the River Eden which reached 1520 cumecs. In contrast the Bangladeshi volume of precipitation was much

Unfortunately various forms of pollution‚ including runoff and erosion‚ can interfere with the health of the watershed. Therefore it is important to protect the quality of our watershed. It is important for the people to be aware of the events that happen around them‚ especially the information that concern

To protect the land cover and soil we make a grassed water way which takes the runoff water away from the cropping field‚ and we provide the bench terraces which make the cultivation easier and allow inter culturing operation comfortably‚ it reduces the soil erosion as well as unnecessary water logging in some areas.

Plant roods bind the soil‚ while leaves protect it from the impact of heavy rain whilst layers of humus (leaf matter) helps to absorb rainfall and reduce runoff of soil into small rivulets. (small stream.) Any sort of slope will make water erosion more severe‚ as water attains more force thus dislodging plants and more soil. If the water is evenly seething and eroding the soil‚ this is known as “sheet erosion”The
