摘要

本文介绍了对波兰北部卡斯祖比海岸海岸悬崖剖面的多时相数字地形模型[DTM]研究。该分析研究基于2010年至2016年间获得的五个激光雷达衍生DTM。主要想法是逐年或每两年比较一次变化（取决于可用的材料）。使用各种地质处理技术对DTM进行了分析，结果绘制了斜率图和z值最大变化的梯度图。还准备了这些参数的时间变化分析，以便可视化和跟踪悬崖内发生的山体滑坡。此外，还估算了滑坡中泥沙增减的面积，以及滑坡内垂直位移的平均速率和海滩上的泥沙平衡。这些研究还允许讨论大规模浪费过程与海岸保护性基础设施之间的相互关系。收集到的信息使我们能够找到陡峭悬崖海岸山体滑坡的机制和发展。

Tracking cliff activity based on multi temporal digital terrain models – an example from the southern Baltic Sea coast

A multi-temporal digital terrain models [DTM] study of a coastal cliff section at Kaszuby Coast (northern Poland) is presented in this paper. The analytical study was based on five LiDAR-derived DTM acquired between 2010 and 2016. The main idea was to compare changes year by year or every two years (depending on the available material). The DTM were analysed using various geoprocessing techniques, and as a result the map of slope and the gradient of maximum changes in z-value were prepared. The analysis of the temporal variations of these parameters were also prepared and allowed to visualize and track the landslides that occurred within the cliff. What is more, the areas of sediment increasement and decreasement, as well as the average rates of vertical displacement within the landslides and sediment balance on the beach were estimated. The studies allowed also to discuss the interrelation between the mass wasting processes and the protective infrastructure on the seashore. The information gathered allows us to find the mechanisms and development of landslides on the steep cliff coast.

期刊介绍： BALTICA is an international periodical journal on Earth sciences devoted to the Baltic countries region and the Baltic Sea problems. This edition as a Yearbook is established in 1961 by initiative of Academician Vytautas Gudelis. Since 1993, an Editor-in-Chief of the journal became Academician Algimantas Grigelis. BALTICA is published biannually (in June and December) in cooperation with geoscientists of the circum-Baltic States. BALTICA is publishing original peer-reviewed papers of international interests on various Earth sciences issues. The particular emphasis is given to Quaternary geology, climate changes and development of ecosystems, palaeogeography, environmental geology, as well as stratigraphy, tectonics, sedimentology and surface processes with relevance to the geological history of the Baltic Sea and land areas. Journal emphasizes modern techniques, methodology and standards. The journal structure comprises original articles, short reviews, information, bibliography.
