Points along Channel

Since some design parameters (e.g. waves) can vary along the channel, channel dimensions are determined by checking a series of points along the channel. These points are spaced along the channel with the following criteria:

• Points along straights are separated by not more than the minimum design vessel length (rounded to the nearest 25m)
• In bends, the same criteria are applied as for points. Additionally, points are not more than 5° apart around the curvature of the bend

The critical point for a particular channel element (i.e. straight section or bend) is found. This is the point which requires the deepest or widest channel section, and the width and depth for the whole channel element is set based on this point. While widths and depths cannot vary within a single channel element, it is possible for the dimensions of channel elements to be different.
