Ground based LIDAR gives the opportunity to measure surface changes in a very high spatial and temporal resolution. During the submitted project, the erosion of steep and (partly) unvegetated slopes in four different climatic regions (cross profile from the Franconian Alb over the Alps to Tuscany) will be measured using Ground-based LIDAR. Using the data of these measurements, the importance of single geomorphic processes for the total erosion under different climatic conditions on such slopes and the interactions between these processes will be analysed in detail. On the basis of this data, both an empirical (SCA model) and a physical (Erosion 3D) model will be calibrated and validated in order to adapt them to fit the investigated slopes.

地面激光雷达提供了以非常高的空间和时间分辨率测量地表变化的机会。在提交的项目期间，将使用地面激光雷达测量四个不同气候区域(从阿尔卑斯山到托斯卡纳的弗兰科尼亚山脉)陡峭和(部分)无植被的斜坡的侵蚀情况。利用这些测量数据，将详细分析不同气候条件下单一地貌过程对这些坡面总侵蚀的重要性以及这些过程之间的相互作用。在这些数据的基础上，将对经验(SCA模型)和物理(侵蚀3D)模型进行校准和验证，以便使它们适合所调查的斜坡。
