Based on the different hydrological and hydraulical conditions of channel reservoirs during a hydrological year, the prediction model of their total phosphorus (TP) was established by combining the 2-D straight river model and the polar coordinate diffusion model proposed by A B Karaueshev (A B Kapayщв).

The respective features of near\|bank pollution belts in both the natural channel before reservoir construction and the channel reservoir are studied through an.

At first, the research situations and significance about the total phosphorus prediction model of channel reservoir are presented.

Influence of dynamic capacity of river-type reservoirs on real-time flood regulation;

The construction of a river-type reservoir will normally cause a change of hydrodynamic condition and a decrease of flow velocity in branch bays,leading to the formation of algae bloom when appropriate environmental conditions and sufficient nutrient supply are encountered,and thereby,causing the deterioration of fluvial ecosystem therein.
