The revised conditions.........would you average the 1.74 & 2.03 since each is correct for a 90 quadrant behind the house ??
the house is at 1000' with another 560' above (at 45 deg), then Lh = 780' That would change up the numbers a bit.
H/Lh = 1560/780 = .5
K1 = 0.43 (2D escarpment)
K2 = 0.79 for x/Lh = 560'/780'= 0.718
K3 = 0.94 for z/Lh = 22'/780' = 0.0282
K1 = 0.43 (2D escarpment)
K2 = 0.79 for x/Lh = 560'/780'= 0.718
K3 = 0.94 for z/Lh = 22'/780' = 0.0282
Kzt = (1+K1K2K3)^2 = 1.74 1.99
the house is at 1000' with another 60' above (at 45 deg), then Lh = 530' That would change up the numbers a bit.
H/Lh = 1060/530 = .5
K1 = 0.53 (3D Hill)
K2 = 0.93 for x/Lh = 60'/530' = 0.1132
K1 = 0.53 (3D Hill)
K2 = 0.93 for x/Lh = 60'/530' = 0.1132
K3 = 0.86 for z/Lh = 22'/530' = 0.0415
Kzt = (1+K1*K2*K3)^2 = 2.03 2.3
