Improvement of calculation method for practical and economical cross-section of the trapezoidal channel with an arc slope angle;

Research of the frost heaving destruction mechanics model of the concrete lining channel in trapezoidal section with curved slop toe

Analytical solution to concentration distribution discharged from a stream of effluent into trapezoidal channel flow;

A series of experiments are carried on through two kinds of different link transition section(the distortion and the partition wall) as well as the different weir thickness and gap width at the trapezoidal channel.

By means of iteration, a table is achieved for the solution of depth to width ratio and width to depth ratio of trapezoidal channels.

The discharge coefficient (C_d) of cylinder flow-measuring flume on the trapezoidal canals has a good correlation with the relative water head (H_s/L) and co.

This paper introduces the application of concrete arc base trapezoid al impervious canal in water-saving transformation project in Jiamakou irrigate d area, analyzes the merits of the arc base trapezoidal impervious canal, and su ms up the key points of the impervious design and construction design.
