It is estimated that 90% of sewage in cities in developing countries are today discharged untreated into water bodies. The physical, biological, chemical and geologic interactions among different components of the environment that occur within a wetland. Anzali wetland complex is a good example of a natural wetland, characteristic of the South Caspian lowlands. It supports an extremely diverse ...

This paper introduces a mixed integer programming model to find the optimum development plan for port Anzali. The model minimizes total system costs taking into account both port infrastructure costs and shipping costs. Due to the multipurpose function of the port, the model consists of 1020 decision variables and 2490 constraints. Results of the model determine the optimum number of berths tha...

Bream (Abramis brama, Berg, 1949; Family: Cyprinidae) is commercially valuable fish in the Caspian Sea fishing industry. Iranian Fisheries Organization annually produces and release up to 19 million Bream fries size for recruiting of this species. Its fries are mostly released into the Anzali wetland with 4 ppt salinity. Meanwhile, they sometimes are released into Sefidrood River (0.5 ppt), Sef...

The construction of new breakwaters in Anzali port has had a significant impact on the water body international lagoon. wetland is under threat from sediment influx mountainous regions, and study used satellite image processing to demonstrate how impedes natural transfer lagoon sea. methodology employed hybrid approach combining two methods: normal index (MNDWI) supervised classification (SVM) ...

The Anzali Ramsar Convention wetland is located in an ecologically and economically important region in Iran. The wetland is largely surrounded by agriculture, natural forests and rangelands (approximately 36% and 63%, respectively). Urban areas consist of less than 1% of the total area. Urban land use produces the highest rates of nutrient transfer into the lake as TN, TP and BOD5 equal to 24,...

BACKGROUND In Anzali Lagoon, there are some endemic and exotic fishes. The present study was conducted to compare the parasitic fauna of Blicca bjeorkna, as an endemic fish and Hemiculter leucisculus, as an introduced fish to the lagoon. METHODS A parasitological investigation was done on 78 specimens of B. bjoerkna and 114 of H. leucisculus. The fishes were collected from August 2009 to Apri...
