vdamheight {viadam}R Documentation

Vertical dam height

Description

Computes vertical dam height from dam height normal to the terrain, deflecting angle, slope of the terrain, and the angle of the dam side with respect to the terrain.

Usage

 
vdamheight(phi,psi,alfa,h)

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.
h dam height normal to the terrain.

Value

vdamheight returns a vector of vertical dam heights with the same number of elements as phi, psi, alfa or h.

Note

The vertical dam height is measured in a vertical cross section normal to the dam or obstacle axis in the map plane.

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