Water Supply And Sanitation In Bangladesh
Bangladesh is faced with multiple water quality and quantity problems (such as salinity, groundwater depletion and natural arsenic contamination of groundwater) along with regular natural disasters, such as cyclones and floods. Available options for providing safe drinking water include Tube well, tubewells, traditionally dug wells, treatment of surface water, desalination of groundwater with high salinity levels, and rainwater harvesting. Only 56% of the population was estimated to have access to adequate sanitation facilities in 2010. A new approach to improve sanitation coverage in rural areas, called the community-led total sanitation concept, has helped to increase the sanitation coverage. Bangladesh has a low level of cost recovery due to low tariffs and poor economic efficiency, especially in urban areas where revenues from water sales do not cover operating costs. Water resources Surface water Bangladesh has an enormous excess of surface water during the Monsoon of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sharing Of Ganges Waters
A long-standing dispute exists between India and Bangladesh over the appropriate allocation, and development, of the water resources of the Ganges River, which flows from northern India into Bangladesh. The issue had remained a subject of conflict for almost 35 years, with several bilateral agreements and rounds of talks failing to produce results. However, a comprehensive bilateral treaty was signed by Indian Prime Minister H. D. Deve Gowda and Bangladeshi Prime Minister Sheikh Hasina Wajed on 12 December 1996 in the Indian capital New Delhi. The treaty established a 30-year water-sharing arrangement and recognised Bangladesh's rights as a lower-level riparian. Background Descending from India's northern plains, the Ganges river forms a boundary of 129 kilometres between India and Bangladesh and flows for 113 km in Bangladesh. At Pakaur in India, the river begins its attrition with the branching away of its first distributary, the Bhagirathi River, which goes on t ...

Reverse Osmosis
Reverse osmosis (RO) is a water purification process that uses a partially permeable membrane, semi-permeable membrane to separate water molecules from other substances. RO applies pressure to overcome osmotic pressure that favors even distributions. RO can remove dissolved or suspended chemical species as well as biological substances (principally bacteria), and is used in industrial processes and the production of potable water. RO retains the solute on the pressurized side of the membrane and the purified solvent passes to the other side. The relative sizes of the various molecules determines what passes through. "Selective" membranes reject large molecules, while accepting smaller molecules (such as solvent molecules, e.g., water). Reverse osmosis is most commonly known for its use in drinking water purification from seawater, removing the salt and other effluent materials from the water molecules. As of 2013 the world's largest RO desalination plant was in Nahal Sorek, So ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Water Metering
Water metering is the practice of measuring water use. Water meters measure the volume of water used by residential and commercial building units that are supplied with water by a public water supply system. They are also used to determine Fluid dynamics, flow through a particular portion of the system. In most of the world water meters are calibrated in cubic metres (m3) or litres, but in the United States and some other countries water meters are calibrated in Cubic foot, cubic feet (ft3) or US gallons on a mechanical or electronic register. Modern meters typically can display rate-of-flow in addition to total volume. Several types of water meters are in common use, and may be characterized by the flow measurement method, the type of end-user, the required flow rates, and accuracy requirements. Water metering is changing rapidly with the advent of smart metering technology and various innovations. In North America, standards for manufacturing water meters are set by the Ame ...

Effects Of Climate Change
Effects of climate change are well documented and growing for Earth's natural environment and human societies. Changes to the climate system include an Instrumental temperature record, overall warming trend, Effects of climate change on the water cycle, changes to precipitation patterns, and more extreme weather. As the climate changes it impacts the natural environment with effects such as more intense forest fires, thawing permafrost, and desertification. These changes impact ecosystems and societies, and can become irreversible once Tipping points in the climate system, tipping points are crossed. Climate activists are engaged in a range of activities around the world that seek to ameliorate these issues or prevent them from happening. The effects of climate change vary in timing and location. Up until now the polar amplification, Arctic has warmed faster than most other regions due to climate change feedbacks. Surface air temperatures over land have also increased at ab ...

Sea Level Rise
The sea level has been rising from the end of the last ice age, which was around 20,000 years ago. Between 1901 and 2018, the average sea level rose by , with an increase of per year since the 1970s. This was faster than the sea level had ever risen over at least the past 3,000 years. The rate accelerated to /yr for the decade 2013–2022. Climate change due to human activities is the main cause. Between 1993 and 2018, melting ice sheets and glaciers accounted for 44% of sea level rise, with another 42% resulting from thermal expansion of water. Sea level rise lags behind changes in the Earth's temperature by decades, and sea level rise will therefore continue to accelerate between now and 2050 in response to warming that has already happened. What happens after that depends on future human greenhouse gas emissions. If there are very deep cuts in emissions, sea level rise would slow between 2050 and 2100. The reported factors of increase in flood hazard potential are often e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
