deep concave slope 深凹边坡
horizontal concave slope 平面凹形边坡
concave slope variable turn 凹变坡转弯
concave-bank subgrade slope 河湾路基边坡
On compound slope field, the soil erosion displayed strong, week and depositional on steep, gentle and concave slopes, respectively.
在复合坡面，随坡面的陡、缓、凹，土壤侵蚀表现强、弱、沉积；
The number of GM decreased as the slope exposure turned from N to S, as slope increased, and as slope shape turned from convex to concave.
GM平均胸径还与坡位正相关； GM数量沿N→S的坡向梯度减少，而随坡度增大及坡形由凹转凸而增加；
The latter often shows that there is a "chop concave" on the slope base.
后者常表现为斜坡坡脚部分存在有“嵌凹”；
