  • River safe yield with the constraint of a contracted rectangular weir for surface water supply

    Aydin et al. introduced the weir velocity concept in 2011 for discharge measurement in contracted rectangular sharp-crested weirs. Gharahjeh et al. further reinforced this formula in 2015 to allow discharge to be computed using only weir velocity and crest width. These newly introduced expressions are tested and demonstrated to determine surface water yield of Tapah River in ...

  • Mining water from gypsum

    Water resources in the world are scarce and unevenly distributed. In deserts, the only source of drinking water is groundwater, often saline and of poor quality. In many places, the groundwater levels have dropped dangerously due to overexploitation. Gypsum deposits, that are very common in deserts, are a potential source of drinking water, a fact that is realised by very few people. Gypsum ...

  • Bottled versus tap water fact sheet

    Where does bottled water come from? Those beautiful mountain illustrations on water bottles are often very far from the true source of the water inside. Bottled water sources can be hard to track down, as bottled water manufacturers are not required to disclose where the water comes from or for that matter, what’s in their water. In fact, the best indicator of what kind of water ...
