The history of glaciers can be seen as of central importance for this. The Ice Age glacial erosion created V-shaped valleys, which with their steep flanks - as a consequence of the interglacial formation of V -valleys - have prepared and brought about landslides as well as rockslides and the hazards, combined with them. The same is true for the moraines, which the gla ciers have deposited high-up in the valley flanks and related loose stone deposits. Dry and wet mass movements follow after heavy precipitation, especially in the semi-arid investigation areas, and are catastrophes for the settlements and the communication routes in the valley floors. Their key-forms are debris cones and debris slopes, as well as mudflows and alluvial fans. In addition to the Ice Age glaciation history, as a preparatory, indirect factor, the Holocene to present glaciation history is, as a result of the danlming-up of glacier- and moraine lakes and their outbursts, a direct risk f | 出版日期 | Book 1998 | 关键词 | erosion; natural disaster; production; hydrogeology | 版次 | 1 | doi | https://doi.org/10.1007/978-94-011-5228-0 | isbn_softcover | 978-94-010-6200-8 | isbn_ebook | 978-94-011-5228-0Series ISSN 0924-5499 Series E-ISSN 2215-0072 | issn_series | 0924-5499 | copyright | Springer Science+Business Media Dordrecht 1998 |
