damangle {viadam} | R Documentation |
Computes the angle of a dam side with respect to the sloping, upstream surrounding terrain from deflecting angle, slope of the terrain, and the steepest slope of the dam side.
damangle(phi,psi,alfas)
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. |
alfas |
the steepest slope of the dam side. |
damangle
returns a vector of angles subtended by the dam side with respect to the
terrain with the same number of elements as phi
, psi
or alfas
.
The angle of the dam side with respect to the sloping terrain is measured in the direction normal to the dam axis in a plane normal to the upstream terrain.
The angles phi
, psi
and alfas
are given in radians.
