Design Channels


MIDUSS lets you design channels with two types of cross-section to carry the current peak flow in the Inflow hydrograph.   If no hydrograph has been calculated you can enter a constant flow value.

The cross-section can be:

  1. A general trapezoidal shape defined by a base width and left and right sideslopes.
  2. An arbitrary shape defined by up to 50 pairs of coordinates.

In both cases a table of depth, gradient, velocity values is displayed which represent feasible designs. You can select from this list by double clicking on a row of the table or you can specify a total depth and gradient explicitly.

Pressing the [Design] button causes a uniform flow analysis to display the uniform flow depth, critical depth, average velocity and channel capacity.

You can experiment with alternative schemes until satisfied. Pressing the [Accept] button saves the current design.

An arbitrary cross sectin can be drawn with the mouse pointer and the coordinates iof the selected points are shown automatically in a grid.  These coordinates can be edited to refinen the drawing.  If the length dX of a segment is altered all the points to the right are adjusted automatically.
