The research aims at initiating a new refined methodology for landslide prediction by modeling responses of the eco-hydroclimatic environment of hillslope in a changing climate. The proposed methods are twofold: utilization of UAV LiDAR for detecting geomorphological conditions and vegetation canopy structure of hillslope in a high resolution, and application of measured field data to assess loading and stress condition in the surface soil layer of hillslope for predicting landslide occurrence. For the target area of Rokko mountain in Hyogo, an assessment model has been developed and being calibrated in progress. For assessment, the features of extreme rainfall and its relation with ground temperature have also been obtained by using observation and climate projection data.

该研究旨在通过模拟气候变化下山坡生态水文气候环境的响应，启动一种新的精细滑坡预测方法。所提出的方法有两个方面：利用无人机激光雷达以高分辨率探测山坡地貌条件和植被冠层结构；利用现场实测数据评估山坡表层土层的荷载和应力状况，以预测滑坡发生。针对兵库县六甲山目标区域，已开发出评估模型并正在进行校准。为了进行评估，还利用观测和气候预测数据获得了极端降雨的特征及其与地面温度的关系。
