increase in sea level rise etc. Over–saturated soil (when the ground can’t hold in any more water and could turn into mud etc): Infiltration can’t take place due to the soil’s impermeability resulting in so then surface run off will be increased. High River‚ Stream‚ and Sea Level (caused by heavy rain/particle expansion): The amount of water in the channel becomes too high‚ forcing water inland. Objects such as fallen trees and littering can causes blocks in the flow of the water‚ which can also cause

region and glaciers‚ rivers‚ and streams eroded the Rocky and Appalachian Mountains. Today‚ mountain erosion continues to carry debris out onto the plains. When melting snows and heavy rains fill rivers beyond their banks‚ they flood. The waters spread out over the surrounding landscape and drop the load of mud‚ sand‚ and silt they normally channel downstream. Over thousands of years‚ the sediments build up floodplains. Alluvial plains often form where steep mountain valley rivers gush onto more

Mrs. Wang’s clan village‚ the Village of Three Mile Wangs‚ on the flat banks of the Yellow River‚ had never even seen a Japanese person. Only the war caused them to talk about the Japanese. It was an early summer evening. After her supper‚ Mrs. Wang had climbed the dike steps‚ as she did daily‚ to see how high the river had risen. She was more afraid of the river than of the Japanese. She knew what the river could do. One by one‚ the villagers had followed her up the dike. They stood staring down

Streams and rivers * WetlandsPonds and lakes These regions range in size from just a few square meters to thousands of square kilometers. Scattered throughout the earth‚ several are remnants from the Pleistocene glaciation. Many ponds are seasonal‚ lasting just a couple of months (such as sessile pools) while lakes may exist for hundreds of years or more. Ponds and lakes may have limited species diversity since they are often isolated from one another and from other water sources like rivers and oceans

around on the streets‚ one thing people always notice is trash and polluted rivers. People throw things carelessly‚ which can block the canals and rivers‚ making them polluted and hard to maintain. Another part is the amount of weight we produce; cars‚ buildings adds on to the weight in which can cause the land to sink. For the past two decades‚ the environment and population density have changed. Over time‚ the quality of river catchment is decreasing due to the lack of responsibility in disposing waste

Essay #4 What is flooding? Flooding is when a place or area is covered or submerged with water. There are many things that cause flooding. That includes heavy rainfall‚ which can cause rivers to overflow and devastate a whole community. Another culprit to flooding is hard dry soil. When the soil has not been replenished in a long period of time‚ it cannot absorb the downpour rapidly enough. Building on flood plains is also a growing concern. Floodplains are flat areas of land with higher

Streams and Rivers: The most prominent physical characteristic of streams and rivers is their current. Headwater streams are generally cold‚ clear‚ turbulent‚ and swift. Streams and rivers are stratified into vertical zones. The salt and nutrient content of streams and rivers increases from the headwaters to the mouth. Damming and flood control impair the natural functioning of stream and river ecosystems and threaten migratory species such as salmon. Estuaries: is a transition area between river and sea

many parts of the river basin‚ e.g. Nepal‚ Bhutan and Northern India. This is a result of population growth (more wood is needed for cooking and heating. Also more forests are cleared for farm land). This has led to increased flooding. This is a result of: * More erosion of soil as roots no longer hold soil together * Less take-up of water by plant roots * Less interception of rain fall by vegetation cover Positive impact of flooding in Ganges/Brahmaputra river basin Regular annual

Being a great fan of Dr.A.P.J. Abdul Kalam I’ve always been inspired by him. I’m one of those lucky ones who had the golden opportunity to meet him in person when I was in 9th grade. I was ignited by his thoughts and views and I thought Vision 2020 was the best action plan we could have for our beloved country- INDIA. But then today while I was writing this post my Dad happened to have a look at what I was up to. He asked me what my vision for India was. I said all the great things that I had read

steep slopes. Steep slopes mean that rainwater will run straight off the surface. Additionally‚ in both these places‚ there were converging rivers. In Boscastle there were three; the Valency‚ Jordan and Paradise. Similarly in Bangladesh‚ large amounts of water pass through due to the 2 major rivers which run through; the Ganges and the Brahmaputra. These rivers have large drainage basins which automatically increase the flooding risk. Over half of Bangladesh is less than 1m above sea level and around
