Features and Limitations
Input Data
Output Data
Output from the program is of two types – tabular and graphical.
Tabulated data includes full set-out dimensions (offsets and invert levels) for the spiral fans and barrel of the designed structure. The radius of curvature of the iso-level lines in the fan are also listed.
These data are plotted in simple graphs to enable the user to gain a visual appreciation of the shape and dimensions of the structure.
Caution Notes For User
MELS performs the design and hydraulic analysis of MEL culverts.
Other important aspects of the design include surface treatment of the fans to avoid erosion, low flow channels/pipes in regions where standing water in the depressed invert of an MEL structure is undesirable and provision of adequate freeboard. These issues are discussed in the Design Guidelines but are not part of the MELS software.
