Along the direction of groundwater runoff, there was no obvious change overall. Nevertheless, there was an upward trend in Na+ concentration and a downward trend in Ca2+ and Mg2+ concentrations in both shallow and deep groundwater from Zone 1 to Zone 2 (Fig. 2), indicating the occurrence ...
Water loss refers to the combination of leakage and wastage from the distribution network, including apparent losses (such as meter errors and unauthorized consumption) and real losses (such as leakage from transmission mains and service pipes). ...
(CHEC), the port was delivered to the Israeli government ahead of schedule in May 2021. This ambitious infrastructure undertaking, backed by a 900 million USD investment, spans 2,363 meters of shoreline, including a 1,243-meter-long container terminal, and boasts an annual container throughput ...

For the UFM, a simple linear expansion of the meter body results in the following correction factor: (2)kT=(1+αΔT)3≈1+3αΔT. When a UFM is calibrated for 20 °C and used at 230 °C, ΔT=210K and α=16ppm/K, there is a change of 1% due to thermal expansion. The ...
In England, this change should form part of a mandated programme to ensure that all households have a smart water meter by 2035, with appropriate support in place for vulnerable customers; In Scotland, Wales and Northern Island we urge the devolved government to review their current positi...
