Rainwater Harvesting Introduction It was very difficult to imagine few decades before that you will require to buy drinking. The use value of water was never undermined‚ but it’s about time that even its exchange value is given due importance. Fresh water today is a scarce resource‚ and it is being felt the world over. More than 2000 million people would live under conditions of high water stress by the year 2050‚ according to the UNEP (United Nations Environment Programme)‚ which warns water

To what extend do you agree with the statement ‘Population growth has brought social and environmental problems‚ and human societies through time have been forced to adapt‚ to find new ways of doing things‚ or perish’ (Scarre‚ 2009‚ p.40? The World has witnessed a dramatic growth in human population since the last ice age. The warmer climate has reduced the number of hostile habitats and allowed for vast numbers of both wild animals and plants to flourish. However‚ at some point both the availability

coefficient of permeability implies the velocity of flow of water through the soil under unit hydraulic gradient‚ and consequently has the same units as that of velocity. A. Variable head test: The variable head test is used for fine grained soils like silts and silty clays. For the Variable head test the following formula is applicable: Where‚ k = Coefficient of permeability at To C (cm/sec). a = Cross Sectional area of stand pipe (cm2). L = Length of soil specimen (cm) A = Cross-sectional area

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

Soil Mechanics Soil is the most misunderstood term in the field. The problem arises in the reasons for which different groups or professions study soils. Soil scientists are interested in soils as a medium for plant growth. So soil scientists focus on the organic rich part of the soils horizon and refer to the sediments below the weathered zone as parent material. Classification is based on physical‚ chemical‚ and biological properties that can be observed and measured. Soils engineers think
