Due to coastal areaschr(chr('39')39chr('39')) dynamic nature, sediment transport frequently changes the shape and morphology of coastal profiles. During the time, coastal areas adjust their sedimentation regimes to such changes. Although constructing structures such as breakwaters and jetties in coastal areas results in disorder in their natural sedimentation regime. To restore the natural regi...

Abstract: Illegal fisheries are one of the reasons for disruption of combination of the seas fisheries, their significant reduction and loss of food security. Therefore, mechanisms have been devised to prevent the depletion and destruction of the seas fisheries. On the one hand, an Exclusive Economic Zone has been created, and the Coastal State has been given the authority to manage and protect...

Coastal aquifers comparing noncoastal aquifers, are faced to natural hazards more rapidly due to incorrect managements (Bear et al. 1999). Aquifer’s vulnerability to various pollutants or intrusion of saline water to coastal aquifers have been studied by several researchers so far (Chachadi et al., 2002 Cardona et al., 2004). Overlay models are produced to overlay physical indicator maps ...

this research was conducted in two protect and destroy region in the middle zagros, in illam province. in order to identification of ecological species group and evaluate density of regeneration, effect of many factors such as protection, vegetation, physiographic factors, physical and chemical properties of soil in study locations were studied. to achieve these purpose number of 54 plots using...

Having a mild and humid climate, Gilan province is closer to the comfort zone than other regions of Iran. In addition, the use of radiation, wind, precipitation and humidity components in the spatial organization of native houses has led to the formation of a semi-open space next to the closed space. In general, the placement of spaces in this climate is such that there is no clear border betwe...
