Spring breakthrough curves induced by conventional advection and dispersion often present a gentle (smooth) change of concentration with time. We investigated an electrical-conductivity breakthrough curve which originated from a chemical re...
Impacts of water temperature on phosphorus release of sediments under flowing overlying water [0.03%]
流动上覆水中水温对底泥磷释放的影响研究
Xiaolong Cheng,Yanan Huang,Ran Li et al.
Xiaolong Cheng et al.
River sediment typically acts a 'sink' or 'source' of phosphorus for the overlying water owing to the adsorption of phosphorous by the sediment or release of phosphorous to the water, respectively. In this study, a method is proposed for th...
