Landslides arcs parameters distribution (a case study of the Kodry in Moldavia)

Abstract

Statistic analysis of landslides arcs curvature radius and coefficient reveals prevalence of active landslides (curvature radius about 50 to 70 m) and stabilized ones (curvature radius 100 to 200 m). Curvature coefficient in most of landslide arcs shows three distinct maxima: 0.3, 0.6 and 1.0. Active landslides mostly develop at slope angles 10 to 12^o.

Active / stabilized landslides ratio at slopes of different orientation indicates the active forms being concentrated on W and E facing slopes, on those slopes arcs of considerable curvature are prevalent, while small curvature arcs show noticeable concentration on N and S facing slopes.
