After construction of a dam across a river, sediments settle behind the dam. It is important for dam designers to estimate the rate and distribution of sediments in the reservoir. In this study, the accuracy of area-increment and area-reduction empirical methods to predict the sediment distribution of Dez, Dorudzan and Shahid Abbaspour reservoirs is evaluated. The last measurement of sediment i...

Knowledge of fish diversity, population data and the stock size, and calculation of the amount of proper catch are essential for a wise and sustainable management of lakes. This research reports a study on fish populations in Dorudzan reservoir, Fars Province. The fish were sampled from three stations in the late Summer and mid Spring 2015, three days each, using nylon gill nets. The mean lengt...

Background and Purpose: Today, by increasing different pollutants, the continuous monitoring of surface waters is essential. Dorudzan Dam is one of the main sources of surface water in Fars Province, Iran; hence, the current study investigated the quality  of Dorudzan Reservoir for drinking and irrigation consumptions. Materials and Methods: In this study, various physicochemical parame...

In the present investigation, co-invasion of Lernaea parasite is reported in some fish species, collected from the Kor River Basin (Dorudzan Reservoir and Kor River), Southwest of Iran in 2010 and 2011.  Lernaea cyprinacea parasites were isolated from the external surface of eye, lips, gills, nostrils, fins, operculum and body of Alburnus mossulensis, Capoeta aculeata, Capoeta saadii (all nativ...

Chemical fertilizers have important role in modern agriculture, and in the other hand led to rigid environmental pollution. Urea fertilizer is one of the most widely used and least expensive nitrogen fertilizers in Iran. Since it is high solubility in water a significant of it, if irrigation or precipitation is heavy, easily washed and led to change to change the quality of groundwater, rivers ...

Background and Aim: Agricultural and industrial activities, as well as population growth, have resulted in increases in the amounts of pollutants in the environment, the human body, and other organisms. Cadmium is one of the common heavy metals entering the biological cycles through different paths causing disease in humans, animals and plants. This study aimed at determining cadmium levels and...
