Investigation of the Effective Factors on Improvement Stakeholders Relationships in Zayandeh-Rud Basin
This study is focused on developing an integrated optimization-simulation model to develop the operation policies for a multi-purpose reservoir. Objective function of the optimization model is considered to be a linear function of reliability, resiliency, and vulnerability of river-reservoir systems. Genetic Algorithm (GA) is used to solve the optimization model in which the coefficients of the...
Water quality and metal contents of sediments were measured in Zayandeh-Rood River. Zayandeh-Rood is one of the most important rivers of Iran. The river water is used for drinking, industrial and agricultural purposes. The anthropogenic impact on the river over the last three decade has proven to be extremely negative due to the quick development of industry. Physico-chemical parameters of wate...
Determination of landscape evolution is useful to well understand the physical environment and it also enables us to conduct the soil related studies. The objective of this study was to establish the historic evolution of Zayandeh-rud Valley from late Tertiary to Quaternary. To achieve this objective, the spatial structure of a representative area of Zayandeh-rud Valley in three dimensions was ...
introduction there is a special competition among many metropolitansfor improving physical and semantic quality of urban landscape to upgrade their positions in global level and attract more tourists. based on such characteristics, one of the important goals of metropolitan management planners of the society is to develop open populated spaces and make leisure centers. urban spaces development ...
background: zayandeh-rood river is the only perennial river in the central basin of iran that has fresh water. water from this source is used for drinking, industrial and agricultural purposes. drinking water is extracted from upstream portion (upstream of chamaseman dam) of zayandeh-rood river and therefore its quality is very important. due to growth of population, industry and other factors,...

administrative regulations for water flow decrease distribution efficiency and effect the economical operation of irrigation networks. complications in distribution systems and the decrease in availability of water require study of the hydraulic performance of existing flow control structures. control systems designed by neyrpic (zayandeh rud network) and usbr (doroodzan network) were investiga...
In a parasitic survey of the native and introduced fishes in the Zayandehrud River, 5 Myxobolus spp. were found in the gills, fins and skin of examined fish specimens. They include M. varicorhini from fin and M. samgoricus from skin of Capoeta damascina, M. musajevi from gills of Capoeta capoeta gracilis, Myxobolus cristatus from Capoeta aculeata, and M. saidovi from Alburnus sp. Data on the lo...
