为实验确定均匀地形的粗糙度提出了客观要求，特别是在给定取角、混合高度和位移长度的情况下，观测阵列与地形情况的匹配。在各种表面上，从可移动的表面（海洋或移动的沙子或雪）到森林和城镇，大约有50个有充分记录的已发表的实验证明符合这些标准，并进行了汇编。结果表明，目前最流行的地形评论低估了实际地形的粗糙度长度。
Objective requirements are drawn up for experimental determination of the roughness of homogeneous terrain, particularly with respect to matching of the observation array to a terrain situation with given fetch, blending height and displacement length. Some fifty well-documented published experiments over various surfaces, ranging from mobile surfaces (sea, or moving sand or snow) to forests and towns, are shown to meet these criteria and are compiled. It is shown that most presently popular terrain reviews underestimate actual terrain roughness lengths by about a factor two.
