Morphology class

Based on the Italian Building Code

T1 = Flat surface; isolated slopes and cliffs with average slope angle i < 15°
T2 = Slopes with i > 15°
T3 = Ridges with crest width significantly less than the base width and 15° < i < 30°
T4 = Ridges with crest width significantly less than the base width and i > 30°

A = Rock
B = Very dense sand or gravel or very stiff clay
C = Dense sand or gravel or stiff clay
D = Loose to medium cohesionless soil or soft to firm cohesive soil
E = Surface alluvium layer C or D, 5 to 20 m thick, over a much stiffer material
S₁, S₂ = ground types requiring special studies
