IAHR, founded in 1935, is a worldwide independent member-based organisation of engineers and water specialists working in fields related to the hydro-environmental sciences and their practical application. Activities range from river and maritime hydraulics to water resources development and eco-hydraulics, through to ice engineering, hydroinformatics, and hydraulic machinery.

FACTORS INFLUENCING PHOSPHORUS DISTRIBUTION IN HYDRODYNAMIC WATER

Phosphorus (P) has strong affinity to react with suspended sediment particles. Spatial diffusion and exchange among different phases of P happen under the influence of flow-sediment transport. This manuscript investigated P sorption onto suspended sediment with the change of flow velocity (V), initial concentration of dissolved P (C ), and sediment 0 concentration (S) in an extended annular flume. The process of kinetic sorption could be finished within 6 hours, with 80% of P sorbed in the first an hour. The change rule of both P sorption amount per mass of sediment at the time point t (Nt), and sorption amount at equilibrium state (N ) were negatively associated with V in low P concentration, and positively e associated with V in high P concentration. Ne would increase with Co and the decrease of S, while the total amount of P sorption (TAPS) in the experiments would increase with both C0 and S. The Langmuir isotherm adsorption model to describe P sorption in equilibrium condition was better than other equations mentioned in this paper.
