Erosion features map is one of the basic maps in erosion and sediment studies considered important in watershed management programs. For preparing soil erosion features map (1:250000 scale), a study was conducted in Jajroud sub-basin of Tehran, Iran. Working unit maps were prepared from integrating: A) plant cover, geology and slope B) land-use, geology and slope C) land-use, rocks sensitivit...
legal establishment of court is the birth of social life; each person should define him/herself against others offence or violation. when a society forms and the legal character appears, the thought of society refers to a person name prosecuting attorney who is the president of the court for defending his/her rights. prosecuting attorney remindterms such as court, crime and punishment. accordi...
the main aim of the present study was to map of urmia lake water surface diminishing rates over a long-term period, and demonstrating the most recent surface of emerged salty alluvial plains. for this purpose, landsat tm, etm+ and oli imageries, observing from 1984 to 2015, were progressively processed to generate most of the thematic models in tempo-spatial context. all multi-date satellite da...
ince the breakthrough of the first sub-meter resolution commercial earth observation satellite IKO-NOS in 1999, many additional high resolution satellites have been launched. In addition, more countries now have their own high resolution satellites. Different applications have been using high resolution satellite imagery such as mapping, digital elevation extraction, and most notably, consumer ...
Some methodologies were compared in providing erosion maps of surface, rill and gully and erosion features, in research which took place in the Varamin sub-basin, north-east Tehran, Iran. A photomorphic unit map was produced from processed satellite images, and four other maps were prepared by the integration of different data layers, including slope, plant cover, geology, land use, rocks erodi...
the history of plant’s used for mankind is as old as the start of humankind. initially, people used plants for their nutritional proposes but after the discovery of medicinal properties, this natural ?ora became a useful source of disease cure and health improvement across various human communities. berberis vulgaris is one of the medicinal plants used in iranian traditional medicine. berberis ...
Cognitive processes are complex and difficult to study because multiple variables can interact and confound the effect of the independent variable. To avoid this potential problem, experimental conditions are rigorously controlled and normative stimuli from standardized data-sets are preferably used. However, norms characterize the stimuli, but they do not prevent potential confounding effects....
gully erosion is one of the most severe types of water erosion that inclusive and global model to represent its development under different environmental circumstances is difficult. moreover, having knowledge about history behaviors of a gully and its advancement requires direct annual monitoring that is not possible in iran conditions because of cost and time. gis and remote sensing with provi...
This paper assesses the potentiality of certainty factor models (CF) for the best suitable causative factors extraction for landslide susceptibility mapping in the Sado Island, Niigata Prefecture, Japan. To test the applicability of CF, a landslide inventory map provided by National Research Institute for Earth Science and Disaster Prevention (NIED) was split into two subsets: (i) 70% of the la...
