sdamslope {viadam}R Documentation

Steepest slope of a dam side

Description

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.

Usage

 
sdamslope(phi,psi,alfa)

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.
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.

Value

sdamslope returns a vector of slopes with the same number of elements as phi, psi or alfa.

Note

The angles phi, psi and alfa are given in radians.
