The result of these sand storms appears as continuous and isolated sand hills. In this paper it was attempted to identify direction and source of harvest points by using sedimentological methods. This was accomplished by step by ...

Monitoring the malfunction of solar cells (for instance, 156 mm by mm) caused soil debris requires a very low flight altitude when taking aerial photos, utilizing autopilot function unmanned vehicle (UAV). The can only operate at certain level that guarantee collision avoidance for obstacles power lines, trees, buildings) adjacent to place where panel is installed. For this reason, photos taken...

Using photos of captive Andean bears of known age and pedigree, and photos of wild Andean bear cubs < 6 months old, we evaluated the degree to which visual information may be used to estimate bears’ ages and assess their kinship. We demonstrate that the ages of Andean bear cubs ≤ 6 months old may be estimated from their size relative to their mothers with an average error of < 0.01 ± 13.2 days ...

The 1811–1812 New Madrid, central United States, earthquake sequence included at least three events with magnitudes estimated at well above M 7.0. I discuss evidence that the sequence also produced at least three substantial triggered events well outside the New Madrid Seismic Zone, most likely in the vicinity of Cincinnati, Ohio. The largest of these events is estimated to have a magnitude in ...

Soil organic matters are considered as the animal and plant residues and active components of soils. The cultivation practices will cause the quick removal of organic matters in soils even in those which are not affected by erosion. This study was carried out to assess the level of soil humus in the pilot area, to investigate the positive or negative effect of humus level on soil and to introdu...

Mass movements are usually natural erosion, but the human can aggravate it by operations such as mining, road construction and destroying the natural vegetation. The purpose of this study is to identify the factors influencing the occurrence of landslides by using a probabilistic model Weight of Evidence and Geography Information System in the Siyahbisheh Watershed. 132 landslide points are ide...

Orthoimages can be used for several purposes. One of them is used them as control information, instead of artificial targets, to determine the exterior orientation of new aerial images. For such a purpose, the image displacements on aerial photos, usually tilted photographs, caused by topographic relief (including the relief of topographic objects) should be removed. In that case the correct ge...
