Symbolic landforms created by ancient earthworks near Lake Titicaca
Interesting landforms created by an ancient network of earthworks are shown, using Google satellite imagery enhanced by an image processing. This network covers a large part of the land near the Titicaca Lake. Satellite images clearly display the slopes of hills criss-crossed with terrace walls and the surfaces of the plains covered with raised fields, indicating that this was once a highly pro...
متن کاملWind Erosion Assessment in Austria Using Wind Erosion Equation and GIS
Soil erosion by wind is a serious problem in many parts of Europe and leads to degradation of the resource soil. In order to achieve sustainable land use, tools to identify problem areas and to evaluate environmental sound management practices are needed and necessary. Until now no wind erosion measurements have been carried out in Austria. For the fist time assessment of soil erosion by wind h...
متن کاملPrioritization of Ghezel Owzan-Sefidrud sub-basins for identification of the erosion-sensitive basins, based on morphometry, erosion rate, and vegetation
Prioritization of watershed basins includes classification of sub-basins on the basis of the existing conditions and erosion intensity, which ultimately leads to protective operations and watershed management in more significant and susceptible sub-basins. In this research, in order to prioritize Ghezel Owzan-Sefidrud sub-basins against sensitivity to erosion, linear and form-based morphometric...
متن کاملLake Bourget regional erosion patterns reconstruction reveals
18 Two well-dated ca. Holocene-long sedimentary sequences from deepest parts of Lake Bourget provide 19 new insights onto the evolution of erosion patterns at a regional scale in NW European Alps. The 20 combination of high resolution geochemistry – XRF core scanning, calibrated by 150 punctual 21 measurements – and isotope geochemistry (Nd) of the terrigenous fraction permitted the 22 reconst...
