triangular channel with slope =1, so m=1
the conveyance is given 67
k = 1 n A R 2 3
for triangular channel
A = m y 2 = 1 × y 2 = y 2 P = 2 y ( 1 + m 2 ) 1 2 = 2 y ( 1 + 1 ) 1 2 P = 2 2 y
So,
K = 1 n ( y 2 ) ( a / p ) 2 / 3 K = 1 n y 2 ( y 2 2 2 y ) 2 3 K = 1 n y 2 y 2 / 3 × 1 ( 2 2 ) 2 / 3 K = 1 n y 8 3 × 1 2 K = 1 2 n y 8 3         e q u l i z e w i t h k = c e 8 3 C = 1 2 n
