冰前区代表冰川和冰缘景观之间的过渡地带。冰缘条件下可能发生冰前带的非冰期过程,反之,冰前带往往发生冰缘过程。因此,冰缘地貌动力学构成了冰前研究的一个固有部分,因此在这里提出的研究项目PROSA的背景下。为了得到一个概述的冰缘地貌动力学在上Kaunertal,我们(一)建立了一个永久冻土模型的基础上BTS测量,(二)分析气象数据,以验证地面迹象的热收缩开裂和(iii)分析地球物理和遥感数据的识别永久冻土蠕变和热岩溶现象。此外,本章包括一个复杂的岩石冰川在Riffltal,上游Kaunertal的支流山谷的形态动力学的案例研究。结果表明,不同的岩石冰川部分和裂片的不同的成因和发展,这主要是在Egesen和LIA stadial冰川前进有关。最近的发展在很大程度上取决于(i)沉积物来源和路径构成不同的活动状态,(i)舌之间的动态相互作用和(iii)地形周围,这已经导致部分岩石冰川的动态不活动。
Proglacial areas represent transitional zones between glacial and periglacial landscapes. Non-glacial processes in the proglacial zone might evolve under periglacial conditions, and vice versa periglacial processes often occur in proglacial zones. Hence, periglacial morphodynamics constitute an inherent part of proglacial studies and are therefore presented here in the context of the research project PROSA. To get an overview of periglacial morphodynamics in the Upper Kaunertal, we (i) established a permafrost model based on BTS measurements , (ii) analysed meteorological data in order to verify ground indications for thermal-contraction cracking and (iii) analysed both geophysical and remote sensing data for the identification of permafrost creep and thermokarst phenomena. In addition, this chapter includes a case study on the morphodynamics of a complex rock glacier in the Riffltal, a tributary valley to the Upper Kaunertal. Results show a diverse genesis and development of different rock glacier parts and lobes, which are mainly related to glacial advances during the Egesen and LIA stadials. More recent developments are largely dependent on (i) sediment sources and pathways constituting diverse states of activity, (i) dynamic interactions between the tongues and (iii) the topographic surrounding, that is already causing dynamic inactivity of parts of the rock glacier.
