For each of these reservoirs‚ water was diverted for human consumption – which oftentimes resulted in wasteful mismanagement. Such human activities became the catalyst of dust bowls where seas or lakes

Green energy is energy that is produced in such a way as to minimize its negative impact on the environment. Traditional energy sources‚ most notably fossil fuels‚ produce greenhouse gases that are believed to be the primary cause of an effect known as global warming or climate change. Sources of green energy‚ such as solar‚ wind‚ geothermal‚ and hydro energy‚ are developed and promoted as alternative sources that make little or no contribution to climate change. Even nuclear energy is sometimes

Rural Land Resources; The Lake District Location; The Lake District is a mountainous region in North West England‚ in the county of Cumbria. The area is in close proximity to Manchester and other surrounding settlements. Transport links also make it accessible to the rest of the UK. The climate is much like Scotland’s‚ yet the area has became an important holiday destination and a desirable retirement place. Ferries make the islands in the lakes accessible‚ and the lakes are used too – for

this century (Chambers et al.‚ 2001). Rainforests assimilate this Carbon Dioxide through photosynthesis and they account for almost 8% of the total atmospheric CO2 recycling (Malhi et al.‚ 1998). Thus maintaining large rainforests as carbon storage reservoirs is an important strategy to control climate change‚ however deforestation continues‚ and this results in an increase in CO2 in the atmosphere as well as the destruction of the

Smallpox is a highly infectious disease caused by the variola virus‚ an orthopoxvirus. Humans are the only known reservoir of this virus‚ thus no known animal or insect reservoirs have been identified. As routine vaccination is no longer undertaken‚ exposure to variola virus has the potential to cause high rates of morbidity and mortality in human population. Following an incubation period‚ infected individuals manifest with prodromal symptoms that include high fever‚ malaise‚ back pain and prostration

`A 20cm diameter pipe of length 100m with z = 60m with f = 0.02 and loss of head due to entrance coefficient k = 0.5. What is the flow rate? Solution: Find the width in m of the channel at the back of a suppressed weir using the following data: H = 28.5cm; d = 2.485m; Q = 0.84 cu.m/sec. Consider the velocity of approach and use the Francis formula. Solution: Water flows in a 2m. wide rectangular flume at the rate of 2.75 cu.m./sec

In Tennessee Valley Auth. v. Hill‚ 437 U.S. 153 (1978) (“Tennessee Valley Auth v Hill”)‚ it was discussed whether a small endangered fish called the “snail darter” could stop the “intended transformation of the river into a 30 mile long reservoir by building the Tellico Dam. Congress had authorised funding for the project in 1967 to generate hydroelectricity‚ create recreational opportunities and flood control‚ and promote shoreline developments.” The question remains‚ what was the case about?
