Based on the geological survey of the open channel of No.

Vertical distribution of oil concentration in sediment laden open channel flow;

Velocity distribution in narrow and deep rectangular open channels;

Distribution of the bubble chord length and numbers in self-aerated open channel flows;

The flux algorithm of open ditch weir was introduced.

According to the motive conditions of the open ditch, we invented a flowmeter, which isn t afraid of sands and is difficult to corrupt and wear and tear.

This paper introduces flow measuring principle of open ditch based on the SCP.

In diversion scheme selection of Suofengying Hydropower Station, five schemes were designed, these are long diversion tunnel on the right bank, short diversion tunnel on the right bank, diversion tunnel plus open canal on the left bank, diversion tunnel plus exposed tub on the left bank and diversion tunnel plus exposed tub and open canal.

In this paper,the rivers flow surface curves of the open canal are newly discussed and classificed by analysing the open canal rivers flow,the physical meaning and unifying of connection among these curves are revealed,anew method of classification is introduced and the tendency law of the rivers flow surface curves is given.
