The hydraulic radius, R, is defined as the ratio of the cross sectional area of the flow, A, to the wetted perimeter of the channel/conduit

R = A / P

The wetted perimeter is the portion of the total channel/conduit perimeter that is in contact with the flowing liquid

]]>

Rectangular channel/conduit

Area: B * y

Perimeter: B + y + y or B + 2y

]]>

Trapezoid channel/conduit

Area: y * (T + B) / 2

Algebraic re-definition

slope, z, defined as the gain in width for every unit of depth (the gradient of the trapazoid's non-parallel sides). The gain in width on one side of the trapezoid is zy, and thus T = B + 2zy

B * y + y^2 * z

Perimeter: B + 2y * sqrt( 1 + z^2)

]]>

Triangular channel/conduit

Area: (T * y) / 2

Algebraic re-definition. See trapeziod B=0.

y + y^2 * z

Perimeter: 2y * sqrt( 1 + z^2)

]]>

Circular channel/conduit

Area: (T * y) / 2

Added the extra programing line to see if it helps.
