Water level is controlled, to determine the elevation of regulating structure, then using empirical analysis method or fine reach simulation, hydraulic formula
Method, three kinds of methods of river dynamics equation determine Width of Regulation Line.The calculation formula of conventional determination regulation parameters is a lot, its
Structure type can be attributed to substantially：In formula：B1For the river width before regulation；B2For the river width after regulation, i.e.,
Width of Regulation Line；H1、H2Respectively renovate front and rear cross section mean depth；A is coefficient, and x, y is index.
As can be seen that the H on the right from formula1/H2It is required that H2>H1When, could constriction river width, the flow velocity scouring depth of increased water flow
Shallow area, in general, this expression formula are only applicable to normal transient section shoal, for the shoal that interlocks, bend shoal and point distributary
Section point, side of confluxing have the shoal of pool, because having reversed stream, pool waters Suo Qu cross sections mean depth H1It is greater than toward contact
H2, according to formula (1), constriction river width is not only not required to, also needs to increase river width on the contrary, this conclusion is obviously unreasonable.For staggeredly shallow
Beach, bend shoal and braided rcach point, side of confluxing have the shoal of pool, the major dimension of its cruiseway regulating structure without
Method is determined by the above method.
