For studying vegetation cover in Choghakhor wetland located in Chaharmahal-o-Bakhtiari province (W Iran), some zones of vegetation life forms were determined and also digitized in order to produce the primary map of plant cover by using LISS-IV sensor of IRS satellite with the spatial resolution of 5.8 m. As aquatic plants in Choghakhor wetland were fully grown, homogeneity or heterogeneity of ...

introduction: ground water as a dynamic and recyclable natural resource in fractured rock terrains are characterized by single and double fracture porosity models. due to the heterogeneous nature of the medium hydraulic properties of these rocks are mainly controlled by fracturing and influenced by multivariate parameters. this heterogeneity is due to various compactions , density of fractures ...

Zoning has always been one of the basic tools of land use control available. Zoning is the regulation and restriction of land uses according to a predetermined plan. This paper will present a look at conventional zoning, its origins, the evolution of the zoning, and the scope of zoning types. Regardless of the varieties, most zoning codes can be classified into at least one of the following bro...

1-introduction one of the problems that is important in the waste management is the topic of waste rural landfill site selection and latex resulting from that in rural areas. the latex can be because groundwater pollution the contamination vulnerability and groundwater protection assessment has proved to be an effective tool for the delineation of protection zones in area affected by groundwate...

An assessment of regional vulnerability to geological disasters can directly indicate the extent and intensity risks within study area; thus, providing precise guidance for disaster management efforts. However, in evaluation susceptibility using a single deterministic coefficient model, direct superimposition values each factor, without considering their objective weights, impact accuracy zonin...

     The main portion of water demands of arid regions like Kashan Plain, Iran supply by groundwater wells. This research was conducted to assess the groundwater quality as well as modelling and mapping groundwater quality in the study area using geosatistics and deterministic techniques. Five water quality parameters, including Electrical Conductivity, Sodium Adsorption Ratio, Total Hardness, ...

Ocean-zoning arguments often center on the biology of ocean species, the geography of fishing-use patterns, and the need for preventing use conflicts. Here we expand this discussion to the social and legal aspects of ocean zoning, focusing on comprehensive planning, segregation of activities into use-priority areas, and the allocation of user rights within each zone. The inclusion of all of the...
