sdamslope {viadam} | R Documentation |
Computes the steepest slope of a dam side from deflecting angle, slope of the terrain, and the angle of the dam side with respect to the terrain.
sdamslope(phi,psi,alfa)
phi |
deflecting angle with respect to the direction of steepest decent in a sloping coordinate system aligned with the terrain. |
psi |
the slope of the terrain. |
alfa |
the angle of the dam side with respect to the sloping terrain in the direction normal to the dam axis in a plane normal to the upstream terrain. |
sdamslope
returns a vector of slopes
with the same number of elements as phi
, psi
or alfa
.
The angles phi
, psi
and alfa
are given in radians.
