The Debris Flow In Log Pod Mangartom,
NW Slovenia
Author(s)

Abstract
In November 2000, heavy rains in Slovenia triggered numerous slope processes.
Among the largest were the landslide and debris flow in Log pod Mangartom in
western Slovenia. This paper describes the main geographical, geological, and
geomechanical features of the debris flow, detailing its causes and describing the
consequences. The facts presented in the article demonstrate that intensive
geomorphic processes are relatively frequent phenomena and are an important
factor in the transformation of the surface in alpine regions.
Keywords: geography, geomorphology, natural hazards, slope processes, debris
flow, landslide, Log pod Mangartom, Slovenia.
1 Introduction
Log pod Mangartom (651 m; population about 130) is a nucleate roadside
settlement located on the right bank of the Koritnica River on the alluvial fan of
its tributary Predelica stream. On November 17, 2000, a debris flow struck the
village. According to Ogrin [11], the Koritnica Valley has a temperate
continental climate. Between 1961 and 1990, an annual average of 2,500 mm of
precipitation was recorded, and avalanches regularly threaten the valley floor
[13]. The area is part of Triglav National Park.
2 Debris flow
At 12:45 on November 15, 2000, a landslide was triggered west of Mount
Mangart (2,679 m) above the valley of the Mangartski Potok stream, which has
an inclination greater than 10%. The landslide stopped almost two kilometers
