The presence of roads in high steep agricultural systems is often linked with landslides *** research aims to model multi-temporal overland flow dynamics in a shallow landslides-prone terraced landscape(northern Italy).The combined use of Remotely Piloted Aircraft Systems(RPAS)and photo-grammetric techniques(e.g.,Structure from Motion-SfM)allowed to elaborate multi-temporal high-resolution Digital Elevation Models(DEMs).Hydrological analyses of water flow's depth alterations due to the road presence were carried out adopting the SIMulated Water Erosion model(SIMWE),focusing on different scenarios considering the presence of the road and assuming its absence through a specific DEM smoothing *** possibility to perform multi-temporal hydrological simulations at a hillslope scale so as to analyse the role played by the road in overland flows alteration is still a challenge to be *** proved the role played by the road in water flows change above the two observed shallow landslides,with respective maximum water depth values equal to 0.18 m and 0.14 *** the contrary,no-road simulations not revealed significant water flows deviations towards landslides,with water depth values around 0 m,underlining that the absence of the road would avoid relevant changes in water flow paths toward the collapsed *** work could be a solid starting point for analyse road impact on runoff dynamics and hillslopes stability also at a wider scale,as well as for planning efficient mitigation intervention so as to reduce the occurrence of similar future scenarios.

月球表面构造对于理解和重建月球地质构造演化具有重要意义,月岭、月溪等线性构造的形态及分布特征与月球内动力构造运动密切相关。极为有限的样品和难度极高的野外勘察使得遥感成为行星科学研究的最主要手段。中国、美国、日本、印度等国先后发射的多颗新型探月卫星获取了大量高质量数据,尤其是高分辨率的数字地形数据(DTM,Digital Terrain Model)。高分辨率的DTM为月球表面构造特征的自动提取带来了新的机遇与挑战。文中利用多种分辨率的DTM数据,基于多尺度数字地形定量分析方法,识别和提取月球表面的线性构造。使用的地形数据包括500m分辨率"嫦娥一号"激光高度计数据,100m分辨率LRO-WAC广角相机数据,60m分辨率的LRO-LOLA激光测距仪数据以及分辨率高达5m的LRO-NAC窄视角相机数据。文中使用地形曲率来识别月溪月岭等线性构造,并利用不同滑动窗口大小和阈值进行线性构造的自动提取。对研究区试验结果的定量分析表明,文中提出的基于地形曲率的月表线性构造自动提取方法是有效且可行的,其结果可为月球表面线性构造解译提供重要参考,提高构造解译时效性和精度。

At 5:39 am on June 24, 2017, a landslide occurred in the village of Xinmo in Maoxian County, Aba Tibet and Qiang Autonomous Prefecture(Sichuan Province, Southwest China). On June 25, aerial images were acquired from an unmanned aerial vehicle(UAV), and a digital elevation model(DEM) was processed. Landslide geometrical features were then analyzed. These are the front and rear edge elevation, accumulation area and horizontal sliding distance. Then, the volume and the spatial distribution of the thickness of the deposit were calculated from the difference between the DEM available before the landslide, and the UAV-derived DEM collected after the landslide. Also, the disaster was assessed using high-resolution satellite images acquired before the landslide. These include Quick Bird, Pleiades-1 and GF-2 images with spatial resolutions of 0.65 m, 0.70 m, and 0.80 m, respectively, and the aerial images acquired from the UAV after the landslide with a spatial resolution of 0.1 m. According to the analysis, the area of the landslide was 1.62 km2, and the volume of the landslide was 7.70 ± 1.46 million m3. The average thickness of the landslide accumulation was approximately 8 m. The landslide destroyed a total of 103 buildings. The area of destroyed farmlands was 2.53 ha, and the orchard area was reduced by 28.67 ha. A 2-km section of Songpinggou River was blocked and a 2.1-km section of township road No. 104 was buried. Constrained by the terrain conditions, densely populated and more economically developed areas in the upper reaches of the Minjiang River basin are mainly located in the bottom of the valleys. This is a dangerous area regarding landslide, debris flow and flash flood events Therefore, in mountainous, high-risk disaster areas, it is important to carefully select residential sites to avoid a large number of casualties.
