The Tunnel Oberau, with a length of 2.9 km, forms the core of the local bypass of Oberau. Between the two massifs Kirchbichl and Mühlberg, the tunnel is situated in the valley of the Gießenbach in alluvial gravel with only a small overlap underneath settlement-sensitive buildings. In this paper, the measures in the tunnel to minimize the settlements of the buildings during the shotcrete excavations are described. Basis for this planning were extensive 3D-FE-calculations. Furthermore, under two buildings a compensation grouting measure was carried out, in order to compensate the occurring settlements. This paper describes how the required time and the amount of injection material (grout) could be reduced during the compensation grouting in highly permeable gravel.

"无焰"氧—燃料燃烧是一项成形技术,已在钢包预热和加热炉上应用。在应用过程中发现,该项技术可以节省约50%的燃料,同时也可以减少CO2排放。将部分无焰氧—燃料燃烧原理应用到高炉热风炉是一种新的尝试。与传统燃烧方式相比,该技术可使操作成本大幅降低,这是源于其有效的废热回收,以及采用"热"的富氧烟气循环来替代"冷"空气。由于用二氧化碳替代了不辐射的氮分子,增强了炉内的热量传递。氧—燃料燃烧概念的一个重要推论就是烟道烟气中CO2的体积分数大约可提升40%~50%,且质量流量变为原来的两倍。该项技术容易实现低成本碳捕获,而且如果实现碳封存,那么就有可能减少整个炼钢流程中大约30%的碳足迹。

Dam removal has emerged in the U.S. as a critical concern for river management. Of particular interest is predicting the quantity of sediment that will be eroded from a reservoir following dam removal, which necessitates predicting the geometry a channel will approach as it forms in the reservoir. The geometry and sediment characteristics of the Koshkonong River were measured as it adjusted to the removal of the Rockdale Dam. Bank stability modeling was used as a tool for predicting the maximum depth of the evolving channel and general agreement was found between depths predicted with the model and those observed up to one year following dam removal. Model sensitivity analysis showed strong control of bank heights by groundwater levels in the reservoir sediment, as well as some control by vegetation established on the sediment surface. Long-term monitoring is needed to assess the accuracy of the model, but preliminary agreement is encouraging for applying this model and similar models to future dam removals.

The digital transformation taking place in all areas of life has led to a massive increase in digital data–in particular,related to the places where and the ways how we live.To facilitate an exploration of the new opportunities arising from this development the Urban Thematic Exploitation Platform(U-TEP)has been set-up.This enabling instrument represents a virtual environment that combines open access to multisource data repositories with dedicated data processing,analysis and visualisation functionalities.Moreover,it includes mechanisms for the development and sharing of technology and knowledge.After an introduction of the underlying methodical concept,this paper introduces four selected use cases that were carried out on the basis of U-TEP:two technology-driven applications implemented by users from the remote sensing and software engineering community(generation of cloud-free mosaics,processing of drone data)and two examples related to concrete use scenarios defined by planners and decision makers(data analytics related to global urbanization,monitoring of regional land-use dynamics).The experiences from U-TEP’s pre-operations phase show that the system can effectively support the derivation of new data,facts and empirical evidence that helps scientists and decision-makers to implement improved strategies for sustainable urban development.

High-latitude terrestrial ecosystems face the triple threats of climate warming,increased exposure to UV arising from polar ozone depletion,and deforestation.Lichen communities of southernmost Chile are recognized for their high diversity,which includes nitrogen-fixing cyanolichens.Such lichens are common on forest trees,contribute nitrogen to forests,and are sensitive to exposure following deforestation(widespread in this region).In a pilot study of exposure effects on tree lichens,using nondestructive imaging methods,we compared lichen communities on trunks of isolated vs.forest tree trunks of southern Chilean beech(Nothofagus dombeyi,Nothofagaceae).We chose trees of similar diameter and trunk lean angle in conserved forest and nearby logged meadow on Navarino Island,XII Region Magallanes and Chilean Antarctica,Chile,within the annual southern ozone hole.Ninety-five percent of cyanolichen records,including Nephroma antarcticum,and 66%of records for other foliose lichens were from the forest,whereas pendulous usneoid lichens dominated N.dombeyi bark at the meadow site.Limitation of cyanolichen growth on isolated trees could affect ecosystem function in this poorly studied habitat.Possible factors contributing to strong community differences were increased light intensity,UV radiation,and wind stress,plus limited ability of lichens to colonize isolated trees in the logged meadow.UV radiation was likely an important stressor for some lichen species but not others.We recommend more extensive monitoring to pinpoint causes of differing lichen communities,and we encourage better protection of bark-dwelling lichens in southern hemisphere regions facing multiple threats.
