Causes of floods Flood is overflow of the huge amount of water onto the normally dry land. Flood occurs when the overflowing water submerges land and causes deluge. It is a cruel and violent expression of water. Catastrophic floods are the floods that are caused by some significant and unexpected events‚ for instance dam breakages. Heavy rainfalls are one of the major causes of floods. The level of water in rivers or lakes rises due to heavy rainfalls. When the level of water rises above the

Introduction: This lab investigates the question‚ what is the water quality of the U-High creek based on micro invertebrates found in the creek? There are many factors that affect the quality of water such as phosphorus and nitrogen levels‚ dissolved oxygen‚ and pH. Phosphorus and nitrogen in water can increase the growth of aquatic plants and algae‚ leading to the decomposition of dead plant material and the removal of dissolved oxygen from water. The total nitrogen concentrations for freshwater

1 Population growth and urban problem in Mumbai‚ India According to G.Tyler(1994)‚ the more poor people move from rural to urban area the more poverty is becoming urbanized. A lot of cities have damage because of the extreme poverty and social and environment in stead of being centers of commerce and industry. In this article I will discuss the problem of slum clearance in Mumbai‚ India. I am interested in poor people in urban area. First I will refer about population growth which is related

Theoretical background Upper course The source of the river is normally found in an area of high ground. The river usually flows through a steep V-shaped valley. Most of the erosion that occurs in the upper course is vertical and as the river bed is eroded lower the valley becomes steeper. The river is narrow with a shallow channel. As discharge is calculated by measuring the cross sectional area of the channel multiplied by the velocity‚ the discharge is small. The river is mainly slow flowing

Deforestation: Deforestation is the excessive cutting down of trees and clearing of forests for different purposes. In other words‚ it is the destruction of forests. These directly and indirectly affect us. Thus‚ deforestation is a serious type of environmental degradation. Soil erosion: Soil erosion can be defined as the destruction of the top layer of the soil as a result of natural or human activities. Soil erosion refers to the carrying away of soil. Soil erosion is also serious type of

Cause and Effects of the Devastation of Nature The devastation of nature is a global concern nowadays. It is because the changes that’s been done to nature which is caused mostly by human activities. When we pollute the air‚ land and water‚ this harms the nature. Bulldozing wetlands and cutting down forest also destroys the nature. These are only few of the activities that contribute to the devastation of nature. Overgrazing and groundwater pumping are some of the activities that damage

Topics to cover in our story book: clean water – don’t use river water‚ water from puddles‚ etc! It IS contaminated and may contain cholera-causing bacteria that will make you sick. Don’t use charcoal whenever you can‚ use LP gas if possible! Why? Remember this tree… with the swing… you could climb it‚ sit under it for shade‚ play on it‚ hide beneath it’s roots‚ etc. But charcoal is made from the destroying this trees… and all these trees. When too many trees are cut down‚ animals (which ones

Vernal pools are small‚ isolated wetlands that occur in a forested setting throughout Michigan. Vernal pools are isolated wetlands because they are not permanently connected to other bodies of water. They need to be flooded and dried out long enough and frequently enough‚ to house flora and fauna that have special adaptations for coping with inundation and water drawdown. They are small enough and shaded enough that recognized open-structure natural community type. The amount of water in a vernal

In the current fiscal year (FY 2009-10)‚ Bangladesh earned US$ 687.53 million by exporting agricultural products which is 4.24 percent of total export earnings (US$16‚204.65 million). In addition to the exports of main agricultural commodities such as‚ raw jute‚ jute goods‚ tea‚ frozen foods‚ the Government has taken steps to increase exports of non-traditional agricultural commodities. Within the broad agriculture sector in FY 2009-10‚ the contribution of agriculture and forestry
