  • Numerical simulation of drainage scenarios for lowering groundwater rise due to construction of a new barrage on the Nile River

    The government of Egypt constructed a New Naga Hammadi Barrage (NNHB) 3.6 km downstream of the Old Naga Hammadi Barrage (ONHB). Upon construction, the water level raised by about 0.5 and 4 m upstream and within the river reach between ONHB and NNHB respectively. In this paper, a two–layer groundwater model was built using MicroFEM to study the groundwater rising problem. The model was used to ...

  • Decolorization of Malachite green dye from wastewater by Populus deltoides: three-level Box–Behnken design optimization, equilibrium, and kinetic studies

    Decolorization of Malachite green in aqueous solution by adsorption onto Populus deltoides sawdust (PSD) was optimized through a four-factor, three-level Box–Behnken design in response surface methodology. The influences of four independent variables such as initial pH of solution (3–7), dye concentration (50–300 mg/L), adsorbent dose (0.2–2 g/L), and temperature (23–50 °C) were studied to ...

  • Impacts of Californian dams on flow regime and maximum/minimum flow probability distribution

    Dams have major impacts on river hydrology with a general tendency to decrease annual maximum flows and increase annual minimum flows. The analysis of 41 streamflow series in California, USA are examined, and the results show that, as expected, the mean values and variations of annual peak flows and maximum flows of different durations are reduced for almost all sites after dam use, and the ...
