Linkages in geographical spaces representing a region is not just a functional system which has been formed by various settlements. It rather takes its power from social, economic and physical networks and their interactions which means it is controlled by aforementioned networks. Therefore, there are always rural area and urban area with some relations or linkages. In this regard, relation mos...
1- Introduction Landslide refers to geomorphologic processes and downward movements of the materials of the slopes, including rock, dirt, or a mixture of them (Moradi et al, 2012).Landslides are affected by various factors, including rainstorms, earthquake shocks, changes in the level of underwater, storms, rapid erosion and a series of factors reducing the strength of materials (Dai et a...
Classifying daily climate circulation patterns has always been considered by climatologists. Investigating climate changes such as rainfall and the temperature in a same single time and place suggests that these changes are strongly influenced by atmospheric circulation patterns. Regarding so, climate changes, known as variables here, such as rainfall, temperature, and other related phenomen...
introduction: determination of waves and the pattern of coastal currents is the first step in finding the effective physical factors on marine environments and coastal regions. moreover, wave induced currents play important roles in the determination of geometry and shape of coasts. in this research, patterns of longshore currents are simulated for situations before and after construction of je...
