ii abstract the legend of human being’s refulgence was distorted completely in the age of modernity. this new age, had some drastic negative effects, besides its positive qualities. one significant negative effect of it was the emergence of neurosis in human beings. aldous huxley’s brave new world was one of the novels of the 02 th century that contained the prophecy of criticizing ...
در این پژوهش مورفولوژی رودخانه تلوار یکی از سرشاخههای اصلی رود قزل اوزن با روشهای مختلف استخراج و بر اساس مدل رزگن در سطح دوم و سوم مورد ارزیابی و طبقهبندی قرار گرفت. هدف اصلی با توجه به جامعیت مدل، طبقهبندی و ارزیابی بازههای آبراهه محدوده مورد مطالعه و در نتیجه درک فرآیندهای موجود و شناخت مورفولوژیک آن است. در این تحقیق جمعآوری دادهها و اطلاعات در خصوص موضوع مورد مطالعه به طور کلی به دو...
abstract cooperative learning refers to small groups of learners working together as a team to solve a problem, complete a task, or accomplish a common goal. in a cooperative environment one’s success is directly related to the success of other members because the focus on the individual shifts towards the group. to test the effectiveness of the method, using jigsaw technique, a study was cond...
Mapping in the Homs region of Syria has revealed a hitherto unrecognized staircase of at least 12 gravel terraces of the upper Orontes River. The terrace gravels overlie Pliocene lacustrine marl and have been calcareously cemented into conglomerates, sometimes interbedded with cemented fine-grained alluvium. A tentative dating scheme, based on modelling the regional-scale surface uplift that ha...
The present paper tries to describe the advantage and improvement of a numerical model when predicting government processes on Flow Rivers. With regard to the important effect of the flow velocity and shear stress forces on river bank erosion, we apply a Two-Dimensional numerical model, named CCHE2D, to simulate river flow pattern at a meandering river Khoshk-e-Rud River of Farsan, 30 Km west o...
introduction lake terraces are geomorphological evidence of climate change during quaternary. location of these terraces location in different elevation shows paleo water lake level fluctuations. investigation about urmia lake terraces was conducted by bobek (1973).he found those terraces in 45-55 meter above urmia water level on that time. according to bobek, development of lake area in paleo ...
The subject of the study is to analysis pattern of Mahabad River channel. This area is located on the south of Uromia Lake. Rapid changing of its channels pattern is an important characteristics which the evaluation of these characteristics is necessary to any hmplementation of development projects. For this purpose, the morphological changes of river channel were recognized by the areal photog...
River deltas and alluvial fans have channelization and deposition dynamics that are not entirely understood, but which dictate the evolution of landscapes of great social, economic, and ecologic value. Our lack of a process-based understanding of fan dynamics hampers our ability to construct accurate prediction and hazard models, leaving these regions vulnerable. Here we describe the growth of ...
