damangle {viadam}R Documentation

Angle of a dam side with respect to the surrounding terrain

Description

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.

Usage

 
damangle(phi,psi,alfas)

Arguments

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.

Value

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.

Note

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.
