SPOTLIGHT Water quality and conservation Although agriculture and industry are the thirstiest of all water consumers‚ household water use accounts for some 10-30% of total consumption in developed countries. As governments develop strategies to promote water conservation‚ an OECD survey of households conducted in 2008 offers insight into what really works. Based on some 10‚000 responses across 10 countries‚ the answer is as clear as what comes out of the tap: having to pay for water

The water cycle is also known as the hydrologic cycle. The water cycle describes the movement of water on‚ above and below the surface of Earth. Water can change states through the stages of the water cycle. Water can change from a solid to a liquid to water vapor in various places of the water cycle. Water moves from one lake to another‚ just like from an ocean to the atmosphere. Water travels by different processes of evaporation‚ condensation‚ precipitation‚ infiltration‚ runoff and subsurface

FLOODS A river flood is a flow in excess of the channel capacity to accommodate the peak discharge‚ and occurs when the amount of water arriving on land exceeds the capacity of the land to discharge that water by infiltration‚ surface flow or drainage pipes. Flooding of river valleys and coastal areas is the most frequent of natural hazards and is one of the most significant in terms of death‚ injuries and long-term social and economic impacts. Flooding regularly claims over 20‚000 lives a year

Water scarcity and global warming Global warming is expected to account for about 20 percent of the global increase in water scarcity this century. It is predicted that global warming will alter precipitation patterns around the world‚ melt mountain glaciers‚ and worsen the extremes of droughts and floods. Global water consumption increased sixfold in the last century - more than twice the rate of population growth - and will continue growing rapidly in coming decades. Yet readily available freshwater

Why is flooding prone to Bangladesh? Bangladesh suffers from regular and extreme flooding for the following reasons‚ first being that its one meter above sea level‚ as well as it being a LEDC meaning it’s a less economical developed country. The rivers leading from the Himalayas flow into the sea‚ when they suffer with heavy rain the excess water starts to over flow and flood and waterlog land and surroundings. The physical causes are‚ the monsoon climate brings very heavy rain and snow‚ and soils
