cover lessens the landscape’s capacity to intercept‚ retainand transport precipitation. Instead of trapping precipitation‚ which then percolates to groundwater systems‚ deforested areas become sources of surface water runoff‚ which moves much faster than subsurface flows.That quicker transport of surface water can translate into flash floodingand more localized floods than would occur with the forest cover.In developing countries‚ people who come from rural often tend to migrate to big citieswhere the

Geography Skills * Legend/key- a table showing what each symbol means on the map * Are reference- 4 figure e.g. 24 26 * Grid reference- 6 figure e.g. 243 265 * Latitude- left to right * Longitude- up and down * Direction of flow of a creek- usually towards a bigger river or sea and you can tell the direction by where the origin point is and where it finishes or joins a bigger river. Also the slope. * * Relief is the difference between the highest and

The Consequences of Water Pollution Annually‚ 90 million people add to the current population of 6.5 billion. At this rate the global population will reach approximately 8.5 billion by 2025 (http://dieoff.org/page120.htm). As the global population grows exponentially‚ so does the demand for natural resources. Of all these natural resources‚ water‚ is the most vital for survival and expansion. Human’s dependency on water will never go away‚ making it a key part to any civilizations future. It

that the ability to absorb increases as you go farther away from a swamp‚ and a group of trees. The ability to absorb also increases based on how much silt is in soil. Introduction In the first article‚ which was a research paper called “Surface runoff and soil water percolation as affected by snow and soil frost” which was written by Holger Johnsson and Lars-Christer Lundin. In the research paper‚ the two discussed an experiment that had been conducted in Sweden. Coupled together‚ a soil water

Nonpoint source pollution is land runoff from drainage‚ rain‚ and seepage and hydraulic modification. It is caused by rain or snow melt that moves through and over the ground. When the runoff moves‚ it collects and picks up manmade and natural pollutants and ends up spilling into lakes‚ rivers‚ streams‚ and coastal waters. Nonpoint source pollution can include things like motor oil‚ toxic chemicals‚ animal droppings‚ trash and even insecticides. Our drinking water needs to be protected. It takes

large scale schemes are necessary for soil reclamation in ravines and badlands of Madhya Pradesh‚ Uttar Pradesh‚ Gujarat and Rajasthan. Several such schemes involving plugging of gully mouths‚ construction of bunds across the gullies‚ leveling of surface‚ a forestation‚ and restriction on over grazing are under implementation in these states. In Madhya Pradesh the World Bank has given an assistance of Rs. 300 million to reclaim about 1 lakh ha of ravine land. (ii) Control of Floods-In India the problem
