Slope Definitions
Waterway Route Slope Grade Definitions
One of the Observable Indicators of Effort Needed for a Route is the Grade/Slope of the Land. G2K Jal-Sethu uses Standard Definitions of the Grade/Slope Along the Waterway to Indicate Local Nature of the Land. This Page Documents Such Definitions.
Δh = rise
l = slope length
α = angle of inclination
As the above picture shows, the arcsine (inverse of Sin(α))
of rise/slope-length will be the angle of inclination, α.
G2K Jal-Sethu uses angle of inclination to identify the Standard Definition of the Grade/Slope
as documented below.
| α From | α To | Grade Definition |
|---|---|---|
| Below -45° | -45° | Very Steep Down Slope |
| -45° | -35° | Steep Down Slope |
| -35° | -24° | Extreme Down Slope |
| -24° | -16.5° | Very Strong Down Slope |
